Some thoughts on ASR and the reviews


I’ve briefly taken a look at some online reviews for budget Tekton speakers from ASR and Youtube. Both are based on Klippel quasi-anechoic measurements to achieve "in-room" simulations.

As an amateur speaker designer, and lover of graphs and data I have some thoughts. I mostly hope this helps the entire A’gon community get a little more perspective into how a speaker builder would think about the data.

Of course, I’ve only skimmed the data I’ve seen, I’m no expert, and have no eyes or ears on actual Tekton speakers. Please take this as purely an academic exercise based on limited and incomplete knowledge.

1. Speaker pricing.

One ASR review spends an amazing amount of time and effort analyzing the ~$800 US Tekton M-Lore. That price compares very favorably with a full Seas A26 kit from Madisound, around $1,700. I mean, not sure these inexpensive speakers deserve quite the nit-picking done here.

2. Measuring mid-woofers is hard.

The standard practice for analyzing speakers is called "quasi-anechoic." That is, we pretend to do so in a room free of reflections or boundaries. You do this with very close measurements (within 1/2") of the components, blended together. There are a couple of ways this can be incomplete though.

a - Midwoofers measure much worse this way than in a truly anechoic room. The 7" Scanspeak Revelators are good examples of this. The close mic response is deceptively bad but the 1m in-room measurements smooth out a lot of problems. If you took the close-mic measurements (as seen in the spec sheet) as correct you’d make the wrong crossover.

b - Baffle step - As popularized and researched by the late, great Jeff Bagby, the effects of the baffle on the output need to be included in any whole speaker/room simulation, which of course also means the speaker should have this built in when it is not a near-wall speaker. I don’t know enough about the Klippel simulation, but if this is not included you’ll get a bass-lite expereinced compared to real life. The effects of baffle compensation is to have more bass, but an overall lower sensitivity rating.

For both of those reasons, an actual in-room measurement is critical to assessing actual speaker behavior. We may not all have the same room, but this is a great way to see the actual mid-woofer response as well as the effects of any baffle step compensation.

Looking at the quasi anechoic measurements done by ASR and Erin it _seems_ that these speakers are not compensated, which may be OK if close-wall placement is expected.

In either event, you really want to see the actual in-room response, not just the simulated response before passing judgement. If I had to critique based strictly on the measurements and simulations, I’d 100% wonder if a better design wouldn’t be to trade sensitivity for more bass, and the in-room response would tell me that.

3. Crossover point and dispersion

One of the most important choices a speaker designer has is picking the -3 or -6 dB point for the high and low pass filters. A lot of things have to be balanced and traded off, including cost of crossover parts.

Both of the reviews, above, seem to imply a crossover point that is too high for a smooth transition from the woofer to the tweeters. No speaker can avoid rolling off the treble as you go off-axis, but the best at this do so very evenly. This gives the best off-axis performance and offers up great imaging and wide sweet spots. You’d think this was a budget speaker problem, but it is not. Look at reviews for B&W’s D series speakers, and many Focal models as examples of expensive, well received speakers that don’t excel at this.

Speakers which DO typically excel here include Revel and Magico. This is by no means a story that you should buy Revel because B&W sucks, at all. Buy what you like. I’m just pointing out that this limited dispersion problem is not at all unique to Tekton. And in fact many other Tekton speakers don’t suffer this particular set of challenges.

In the case of the M-Lore, the tweeter has really amazingly good dynamic range. If I was the designer I’d definitely want to ask if I could lower the crossover 1 kHz, which would give up a little power handling but improve the off-axis response.  One big reason not to is crossover costs.  I may have to add more parts to flatten the tweeter response well enough to extend it's useful range.  In other words, a higher crossover point may hide tweeter deficiencies.  Again, Tekton is NOT alone if they did this calculus.

I’ve probably made a lot of omissions here, but I hope this helps readers think about speaker performance and costs in a more complete manner. The listening tests always matter more than the measurements, so finding reviewers with trustworthy ears is really more important than taste-makers who let the tools, which may not be properly used, judge the experience.

All rooms have bass modes ("resonances" as Jason may be saying) that must be corrected. This requires parametric equalization. Without it, it is only a matter of

You'll fix modal nulls with parametric EQ dude? Wow.

But I agree regarding the culture over at ASR and Amir. He came into the Roon forum to debate Michal Jurewicz from Mytek. Some of the other members became involved and Amir was quite arrogant and condescending. Some of the more fanatical ASR folks won’t leave any room for whatever sound someone likes

As for ASR, it’s a data point, but I’ve found it difficult to digest the toxic culture over there that Amir low key promotes. He’s the Mark Zuckerberg of audio forums - may be intelligent, but socially inept, deflects when challenged, and lacks self-awareness and accountability.

At some point (turning back the clock), i recall that he got banned from every forum i know of. When ya talked to him in person, one could draw some parallels between him and the type of piece that gets fired quickly at any workplace...

What else can you do...but start your own forum?! 😏

 

 

ASR is using that comprise their accepted model of what a high fidelity item of whatever type should do and not do to be rated well. The discovery and validation of some hitherto unrecognized mechanism by which perceived listen quality could be more closely aligned with measurable phenomena would be warmly received. ASR uses the Flo

 

The ASR CFO is still a Revel dealer (Madrona digital), right? Has he managed to put most of his herd on the Revel train (boost sales a bit)? They sound kinda dry and sterile to my ears though the panther always golfs when it sees Revels apparently.

After he got banned on the various forums, does he continue to maintain multiple hidey accounts on the same forums? Or is he finally busy with his followers on his own forum?

Fellas, send the Madrona Digital Revel dealer (who sits around with 1 speaker klippeling away in his garage...whoop di doo) back to his forum and get this type of information directly from the horses’ mouth. You would think he oughta be busy selling Revels, accepting donations from the herd on his forum, etc, staying in his lane. But here he is...trying to do more "outreach" n all (the deep pocket donors exist here, i suppose). Hmmm, maybe, his herd is thinning a bit, when it realizes that the crap he recommends sounds indeed like crap.

Nevertheless, the fanatical side of his herd will eventually settle on some active that looks like a flat line and sounds like a turd.

It’s about what "errors" a designer chooses to live with or not, i.e., what he feels is saleable to a larger number of ears....when these guys oughta run a business (it’s not like they’re incapable of cooking a flat line for a fanatical herd).

 

 

 

ASR is a waste of time for me. Everytime I click on an ASR link I end up regretting it.

Then to have their cult leader show up here ... let’s just say that anyone who posts 7X in a row needs medication.

How do I know? As a great comedian said, "I thought it, then I wrote it."

(cogito ergo sum)

@desktopguy

The Revel dealer’s forum had fallen off my radar (when I got the useless gist of it), until a couple of guys on my listserv mentioned they had been banned for politely disagreeing on some measurement crap, like what is audible or not...In other words, his clan is suppressing anything that deviates from the caricature he paints, in the name of ’science’. But, here he is.

There are specific religions, where the land is no longer secular by law, if members of that specific religion become a majority. The lands where other religions are a majority seem to remain secular by law. You go to that intolerant land and you will have no rights, if you belong to any minority religion. But, when these intolerant fanatics come over to other secular lands (in search of fortunes or whatever), they are real Fin happy with the tolerance, secular laws and the ability to have all their rights (be themselves, speak their minds).

Draw parallels as you wish between the fanatic forum and the rest of em ...

Here is a thread  on ASR titled

"Message to golden eared audiophiles posting at ASR for the first time" with 361 likes

Here is the content of that thread's post. Observe the tone of these goons. 

Hello friend. Hey, listen...we know how it is. Believe me, most of us have been there too. You've spent years toiling in the muck of audiophilia. You read ALL the reviews. You watched ALL the youtube videos. You visited ALL the other forums where everything always makes a difference. You bought the cables and the little bridge thingies for them to sit upon and the benefits were magical. You bought the $1000 IEMs that only truly sang after 250 hours of burn-in. Not 200 hours...or 225 hours, but 250 hours! It must be that for the magic to appear! You converted your entire music library to super high res and enjoyed the blissful new details that never were revealed by the awful, cludgy mess that was 16/44 cd. Never have your ears been assaulted by the likes of bluetooth audio or lossy mp3! You searched endlessly for the perfect dac...the dac that truly brought the magic! You bought one after another, each more expensive than the last, searching for the one, true dac that sounded better than all the rest...

And then you arrived here...and posted about your dac discovery, and were told that a dac shouldn't sound like anything at all! Suddenly your audio reality came crashing down around you. How can this be? Why shouldn't a dac sound great?? Why would expensive dacs even exist if they all sound the same??? Wounded, you lash out angrily! It's idiocy! It's retarded! These people have dead ears! It hurts. We understand. It's been a long time and you've spent a lot of money, all for naught. But once the pain diminishes and you've had time to deal with your emotions just give it some thought. Do some reading here and once your ban is lifted, maybe ask a few questions. Instead of locking your eyes shut against the bright light of objectivity...just open them up a little. Just a squint! Let a bit of that light in and bask in a warm, tubey glow that actually means something! Perhaps, as with many of us, a weight will begin to lift off your shoulders. Perhaps there is freedom in this new reality! You might discover that there is a different way...a way that wields real magic. A way that actually answers questions and reveals truth while at the same time leaving your wallet fat and happy! Welcome my friend. Welcome to ASR where the truth shall set you free!

 

Give these goons a 128 kbps mp3 file, a 10 dollar Bluetooth speaker (set in on a cardboard box from Walmart) and a 2 dollar DAC. They will measure it and attain audio nirvana.

There is absolutely nothing toxic about ASR culture. We thrive on information and knowledge about audio products, engineering and research. If you walk in dismissive of all that, then you will get strong pushback. It is no different than going to your doctor, claiming to know more than him because you know your body and he doesn’t. Most doctors would throw you out of their office if you said that. The toxicity then, is yours, not ours or your doctors.

Why are you here trying to play innocent, pretending to walk the high road n all? Who do you think you’re trying to fool? Does that "inner voice" of yours not let you sleep if you don’t convert the infidels on this forum? Or perhaps, Revel sales are slowing down Madrona? Looking for more donations/donors perhaps?

Go back to your own house and find some peace. On your way out, tell everybody here why you were banned from every audio forum out there. Tell them something about that "inner voice" of yours (you know the one... that goes way back down memory lane). I could characterize it with one 9 letter word, but, i’m sure you’ll give it away soon enough by yourself.

These 2 groups in fact presented pieces of gear as it could be the solution ,on the contrary they should have presented really any pieces of gear as component for an acoustic problem, a problem that cannot be solved anyway either by mere tools or by adding new components . Acoustics parameters controls matter. They supposed "ears/brain/system/room" existence as one so that experience and experimentation could be possible......

 

What i do with my pieces of gear linked as one system in my dedicated room, looking for electrical,mechanical and acoustical basic knowledge is creating my own system...

I mislead no one recommending at each and everyone to study acoustics then they will understand that "timbre" is not a colored illusion for example and they will understand how to use the electrical,mechanical and acoustics parameters to improve their experience.

What is this electromechanical and "acoustical" synthesis/optimization you have done that no one else has been able to do (seemingly)? Can you list the tangible/physical things you did (stuff that went further than the theorycrafting domain)?...I sincerely hope it doesn’t involve a healthy dose of listener self-hypnosis as well! 😬

Because bits are not meanings for a consciousness... And perceived sound experience is not identical with a Fourier map in the Fourier linear time domain.. The ears/brain create his own meanings in his own non linear time domain...

Read about acoustics and replace your electrical techno-cultism tool fetichism with real science ...

@mahgister

Behind the ’apparently scientific’ facade some of these guys are posing under, it is largely a utilitarian life for these ASR types (eat, plug cables into audio precision kit, garbage in/garbage out, look at graph, go to sleep, think about Sean Olive for more street cred, etc). Don’t waste your breath trying to talk about anything that flows into the "metaphysical" realms with this utilitarian crew... 😁

 

Did someone say something eluding to the fact that ASR or Amir owns a 2 channel dealership or has some financial interest in a particular brand of electronics or speakers? Is this true or just hearsay?

@audition__audio He is a Revel/Harman Dealer and his business is called Madrona Digital. You could ask him here what other products he carries/sells.

Feel free to ask him if that would have an impact on competitor brand reviews. We could all get enlightened together.

 

I have no desire to criticize, castigate, or in any other way demean Amir. However, based on the fact that ASR’s reviews do impact (to some degree) a number of companies offering their good-faith best products to the audio enthusiasts’ world, I was surprised to learn that his company, Madrona Digital, carries Harmon/Revel products. [Note: I own Revel Ultima Studio speakers and think them to be marvelous.]. Consequently, I just logged on www.madronadigital.com to learn what other product lines Madrona Digital also carries. The fact that I could not discover any list of them disappointed me. I wish that he would disclose all product lines his company offers for sale -- for the laudable value of "transparency" if nothing else.

Spare the niceties, I am sure this miserable **** cost a lot of brands a lot of money over the years with his loser science turd measurements. Call his company and ask what all he sells. I am sure they will have "golfing panthers" all over the place. I really hope some of the big dogs get together and sue him into poverty. I want to see him cry and beg for donations from his minions to cover his legal fees all day long. That would be a lovely day.

@mahgister , Why don't you and this other son of some eternal mother, hilde, etc (all your apparent rivals) resolve your differences in private messages? Might be easier that way...

@mahgister , Get out of the house and pay a daily visit/walk the dog to some coffee shop near your house, preferably one where intellectuals, university professors, students, spiritual kooks, etc show up. Talk about some of these things in real life, listen to some music on your headphones, take your books, play some chess, start talking to the pretty ladies who show up at such places, etc...i.e., get youself entertained out of the house.

An online forum filled with grouchy old men may not be the right place/medium for the type of conversations circling in your head.

.  I don't know what he's done at Microsoft but he is definitely not a circuit design

Hmm, let's see, a bachelor's degree, few years working as some programmer grunt and ran off into "management" ( the paper pusher and yapper) because even boneheaded programming must have been hard for this cat. No, this dude never designed a circuit in his life....must be way over his head.

Anyone can "use" a audio precision kit, read the manual and spit out garbage all day. I have one and I can train a kid in high-school to do it in flying colors.

Ask him to design/build a audio precision kit or a dac or whatever (Bear in mind, it is also an engineer with a higher aptitude level who does that), but, certainly not this "manager" (paper pusher). 

 

 I suggest many members need to take a long look in the mirror. I see very little difference between Amir's adherence to what he believes and the steadfast adherence to the differing opinions held by so many Audiogon members. I neither support nor oppose Amir's position, but I do support his right to have them. All the rudeness and name calling that goes on in threads like this should be beneath us all and reflects so poorly on the community as a whole.

Anyone with a difference of opinion get banned on the fanatic's forum...KEY DIFFERENCE!

in ROON you can adjust the sound to the "Harmon Curve" via filters? Thanks

Harman curve doesn't sound good dude. It might sound good to the Revel/Harman dealer though.

Read the Yamaha white papers and dump the Harman curve. The button pushing, chart generating Harman sinad moron seems to think he understands music better than the guys who made all your musical instruments.

This just comes to show what a self proclaimed narcissist is like. If you skip to 5:35 of this video, he goes on to say he’s the guy with golden ears. 🙄

It takes a special type of fanatical wacko to get booted out of every forum, get fired from every job, etc. I witnessed it years ago, i.e., how lousy this guy was when he got booted out of everywhere. Such a lousy creature will be forced to become an "entrepreneur" (whoop di doo), start his own lousy forum, etc. Most sociopaths in this world are manipulative enough to sport their cults and fair share of low IQ minions...The rest is history with this guy.

It will be a great day indeed when this thread gets shut down.

I have a few different violins and i’ve recorded the same pieces on them. If i ask this garage monster to point out which violin is which (between 2 of them specifically), i can guarantee 1000%, he couldn’t tell them apart (the trained listener/joker that he is who did some listening training on harman’s website for an hour, wow!!). I could pick out which one is which like night and day (what an anomaly that is to be "scientifically" discarded i must be!!)...It is the type of adaptation that happens when you spent 40 years with such an instrument. But, you couldn’t explain any of it to a low IQ garage monster.

Years ago, when i was visiting Technics HQ, they were demonstrating/showing me circuits with identical measurements that sound drastically different. Can ya explain that to this garage monster undergrad (Circuits 101 moron)? Ya can’t...

Cover his garage (listening room) with glass panels, remove the glass panels and cover with wood. You can be rest assured that the garage monster will measure the same in each case and start jumping up and down about how brilliant he is. But, for anyone with a half a noodle in his head, it will be obvious that the materials which makes up the reflective surfaces in your room drastically affect what you hear. The materials used in drivers themselves affects what you hear...He would measure diddly for you though.

All is lost with the fanatical garage monster.

Later boys....

 

 

 

 

 

 

 

 

 

Mr. Amir in the introduction to one of his videos stated

"we absolutely can measure the differences between cables. The question is do those measurements matter as far as the perception, and the short answer is they don’t"

I am confused now.

Oh, you didn’t know??? The ASR romons can’t perceive cables, but, they can somehow magically perceive 0.0000000001% sinad and they will rank their Toppings and Poppings accordingly on the sinad romon database (purchase guidance shining light).

clips that show the ability of the speaker to do so with sub-bass content.

How fast the speaker is?

There is no such thing. Every sound has its frequency and speaker driver needs to only be "fast" enough to play that. The perception of slow bass likely comes from non-flat bass response of the speaker combined with the room it is in. Both of these are measured using frequency response.

(facepalm) Absolutely Wrong!

@mofojo , A low info computer science undergrad (gpa = 2.0)/programmer grunt wouldn’t have had any coursework/tech electives in vibration, shock mechanics, etc. That’s the domain of the engineering phds (aerospace, MechE, etc), typically, i.e. guys who end up in env.test/sim engineering, spend a lot of time with setting up tests, instrumentation, sim models, validation, etc.

Don’t believe a word coming out of a low aptitude computer science grunt. His only job is to write 2 stupid lines of code without understanding anything about what it’s for.

It is a very simple ring down requirement (threshold) you can pose in the time domain and analyze it for any driver. It will be different for different drivers. In a parallel engineering world, it is done all the freaking time when mechanical shocks (impulses, whatever) are performed for testing components with ED shakers, res plates, etc.

 

Real Test and Measurement Engineers would call audio industry standards rudimentary and lacking rigorous correlation. Maybe that is good enough for audio. However, ASR and Amir routinely claim the scientific, accurate, unquestionable final authority high ground.

He is no such authority.

Here’s a recent example of PS Audio moving on track to post all AP measurements for all their products (Schiit Audio was the first to do this after battling this lousy creature).

The sooner all these companies start providing this information to the masses, the sooner this lousy creature sitting in its garage with a AP kit will be forced into irrelevance, forced to crawl back under its rock.

 

Moral of the story is....If you don’t come out swinging as the expert of what you are and what you produce, any lousy creature sitting in its garage will claim to be the expert of you. PS Audio is learning it the hard way.

 

P.S. While it’s real nice of McGowan to offer the questioner a job, the questioner is a business owner himself with a lot more employees to take care of than PS Audio. Hence, he can’t be working for PS Audio! 😁

 

@mahgister Hey magister! 

You, if anyone, are not polite. You explode with anger all the time and when confronted with your behavior, you apologize. You've done that many, many times. 

As for infestation of threads, that seems to be your forte. You've done it for years. Practically everything you've said in this thread, you've brought up before to the point of boring the heck out of members. You go off on your tangents demanding that others must respond and when one or two do respond, you claim vindication and insult other members when they complain of your tactic of highjacking a thread. 

You post multiple times in a row but no one answers and it spoils the thread and intention of those who want to  participate. Like others have already said, they (we) just pass over what you write hoping you lose interest (at least I do).

If you're of the mind, why don't you go over to ASR and start posting there and let us know how that goes.

By the way, if you really think members here are "gangstalking" you, reflect for a moment as to why and you'll discover it is because of you and your manner.

All the best,
Nonoise

@mahgister , You could move over to ASR, but i highly doubt they would be as open minded or patient with you. It might end quite rough for you there.

Do the following exercise. Scan your own posts spanning the past 6 months and examine the sheer magnitude/number of times you've repeated the same lines (over and over) in every thread attempting to discuss different topics. Does that seem "normal" to you, clinically speaking? Imagine for a moment that it was someone else doing it (because your defense for yourself would be coming in pronto). Would you consider that "normal"? 

I would suggest that you visit with a healthcare professional, especially one who specializes in mental health and maybe say something along the lines of, "Hey doc, i think my mind gets caught in repeat loops all day". Thereafter, he could further examine you and provide a diagnosis/treatment. There are various conditions that respond well to certain types of medication. Good luck.

 

Well, it appears that more ASR minions have landed (Sinad Measurement guy must have called for help, called in the reinforcements to flood this site).

Well, as you boys can see (over and over), this guy measures a dac and throws you some sinad numbers, which forms the basis for his ranking system/purchase guide. He will tell you that’s all there is to it....some low IQ sinad (his path to glory).

But, there’s a lot more you could do with FPGA, etc. When you all dump 10k, 20k, etc on your dacs, there are a lot of tricks contained within such a dac. You can deploy algorithms to pull a bunch of spatial info, deploy hrtf filters, create some level of surround virtualization, etc.

When you hear some dacs, all of a sudden, you heard some depth and layering n all? almost sounds like spatial audio, surround effects at times, eh? That’s right, many of these effects can be attributed to what’s hidden away inside fpga, etc. The dac manufacturer isn’t gonna reveal all his in-house secrets to you, but, you can be rest assured that the above mentioned (or similar) is what’s being deployed.

To reiterate, this guy’s IQ is just not high enough to measure anything on the above mentioned for ya (he wouldn’t know about it)...Sinad is all there is w.r.t ASR minions. Hence, if you just look at his low IQ sinad charts and made your purchase decision, you could get fooled.

Good luck to y’all Audigons.

 

P.S. I can train a 12 yr old to operate my AP kit spit out the same charts. Don't get fooled because you saw a fancy lookin chart that isn't something you see everyday (in your regular line of work).

@deep_333 Sure, DSP can change the way things sound, but I’m not aware of any manufacturers who don’t make such features switchable and therefore hide away their secret sauce. Pretty much all DAC makers strive towards accurate reproduction first and DSP features are add-ons (even if their algorithms are proprietary for this add-ons).

Seems like an odd and unlikely claim but I’d be interested to learn about specific instances!

Well, the issue is....some of you guys are such "intense purists" in constant pursuit of "intense purity".... "avoid dsp like the plague" type of guys.

And yet, all these spatial qualities, surround virtualization type of effects are being delivered to you on your "purist dac" to some degree, as you go up in price...and it just dazzled ya! Yes, yes, just keep hallucinating that it is all because of the purity (the "power supply" kept getting better and better as you went up in price!!, whoop di doo).

No worries, you’ll receive your pure dac and continue to retain your sanity. Enjoy the spatial effects, huuugge deeep soundstage with all kinds of layering n and all. Just don’t worry about "how" it happened (All the purists could lose their "purity" sleep if they found out how).

We don't want a "FPGA gate" like the "MOFI gate" (i.e., the purest of pure analog pursuit and betrayal), do we now.....

 

 

 

In any case, I will not continue debate with you - I see you’ve been too indoctrinated to reach, and my earlier post was in hope you might be able to open your mind to the other half of science,

@kevn , might be better to put this markwd entity on ignore. Looking at post history, it appears to be a recently awakened sleeper cell account.

It could be Majidimehr himself on a hidey account (Engage Clone Mode: Thread narrative support)..or just a very feral loyal ASR Habibi.

You say you dont sell components but own a company that sources components through Harman and perhaps other companies. Madrona sells electronics yes? The money you make off these

@audition__audio

- He is a Harman dealer (Madrona digital).

- All his Revel/JBL speakers get "golfing panthers" all day long. They tower over the competition apparently. I bet all the minions run to him, thereafter and buy some sterile lousy sounding Revels in droves.

- His company is also posed as an integrator, which implies that he sells AV gear. I would wager that he sells Sound United products (Denon/Marantz), because he he’s been measuring the low sinad and granting happy panthers on Denon products. His minions go wild and feral when they hear the word "Denon".

The AV side of his minions don’t just buy 2 speakers, they would be buying 10 for such rigs...So, i would wager that he makes a killing in sales, with the "measurement based" advertising he does on his forum. IMO, it is quite clever how he poses though (as a conveyor of truth through measurements n all instead).

He also begs for donations every time he spits out a chart from his garage...A thoroughly indoctrinated minion would also donate a lot, i’d think (no matter if it’s living paycheck to paycheck or if it’s got deeper pockets). Such is the plight of an indoctrinated minion, i’d think.

In summary, a few lousy charts from a AP kit has made him a lot a dough, i’d bet.

 

BTW, the person who did that is a musician. As a rule, musicians are not audiophiles. My piano teacher wouldn’t know a tweeter from a woofer. If this study applied to audio reproduction, then all musicians would have been diehard audiophiles but they are not.

Musicians are also better at hearing room reflections than general population. Again, that doesn’t make them want to buy fancy audio systems.

- I am a hobbyist musician. I am fairly certain that i have a couple of rigs that can beat the snot out of whatever you’ve got in the garage (Revel Salon n all).

- I have pro musician friends with very legit hifi rigs.

- W.r.t the famous ones, Lisa Gerard, Bjork, Sting, Prince, etc all have/had very high caliber hifi rigs.

Were you hanging out with punk rocker kids screaming into some 100 dollar PA kit at the bar before you made your assessment?

Why does Topping have so many DACs both in the past and currently? Because they sound different from one another. They are designing different sounding DACs with different designs and parts. But why? To stay relevant in this rapidly changing market where new is better? Or perhaps honestly attempting to make better and better DACs?

I borrowed a Topping D whatever it was with the balanced outs (their top model kinda from a couple of years ago). When you played dense tracks is when it started to fall apart, in comparison to my other dacs...(technics, denafrips...or even the Schiit Yggdrasil).

If it is just one boring bird squealing to a single string in a simplistic manner, one may not catch stuff like that about the ASR Topping miracle. These Chifi engineers are fairly sharp though and maybe they’ve learned a thing or two (progressed over time, wouldn’t know until a newer dac is compared)..

I would like to see Majidimehr design/build a dac from scratch though... show us all what a genius he is with his unfathomable bachelors degree n all (instead of dumping rudimentary output from a AP kit all day...that a 12 year old could be taught to do).

 

I tested two Schiit Yggdrasils, finding design errors in them. Company disputed that so a third person volunteered his unit. In doing so, he told me he had bought a Topping and it did not sound as good. He gave me the model number and precise tracks he had used for that testing, and the fact that he had used Stax headphones. I own Stax headphones, and said Topping DAC and same music in high-res (what he had used).

First thing I had to do was match levels as out of box levels were not the same, invalidating any such listening test. After I did that, the two DACs sounded identical in AB tests. The Topping cost 10% of the Yggdrasils.

I was also told that the Yggdrasils needs to warm up. So I left it on for days, measuring it along the way. Its performance never changed.

Again, I duplicated his listening tests to the letter, except that I was careful to match levels when he had not done.

If you all just learned how to properly test equipment so that only the fidelity is being evaluated, then these arguments would all go away. Instead, you keep doing faulty testing, with all manner of mistakes and biases and arrive at conclusions that are not supported by any science or engineering.

Dude (facepalm), the fact that you sat around with headphones comparing that Schiit with something else....no, you have a lot to learn. For starters, I could show you a comparison on a couple of dacs, a good one and a crappy one i have in storage with one of my rigs (NOT HEADPHONES) and it is flipping night and day obvious how one one of them produces a flatass soundfield and the other one doesn’t. You are too stuck in your hole with your headphones and sinad for anything to...., no, I am not going to waste effort bothering to explain anything. I’ll pass a blind comparison 25/25 times or 50/50 times or how many ever flipping times (done it before) in my room (not in your garage) on the test tracks I recorded/will provide. While you chase the dumb didi sinad, I’ll chase the software and dsp instead that’s more meaningful to me.

On the same note, I certainly didn’t join this forum to try and flex intellectually all day against senior citizens from other lines of work....like you’ve doing for pages. But, since that is all you seem to wanna do, I’ve hinted here before that I am a business owner. I own a engineering firm (fab/test floors whatever dude), I’m in the business of producing precision electronics and electromechanical components for some entities. We use million dollars of test equipment, ndt, whatever, the likes of which you will never see or hear about in life. There is nothing you could possibly say that doesn’t sound like simpleton sht to me. I am sure you know about certain types of engg disciplines where you would get embarassed/get schooled very quickly. If I start talking to you about high F high V thermal runaway whatever crap black art circuit to you, nobody on this thread including you will have a clue. So, just simmer down with the flex. Do it on your forum instead.

Y’know, there are guys on my payroll too (i know your kind) who are these younger engg grunts that would talk just like you, possibly. "How could two Fing circuits measure the same, sound different?! Wait, wait, circuits have a sound?!?!" while some of the phds may at least think amd try to keep their mouths shut. Once upon a time, I used to think that way a bit perhaps...But, i got schooled by some audio overlords and it opened my mind. NO, you will never see anything like that in your EE electives or your goofy lil text book.

An older guy like yourself...you should have had opportunities in life to wisen up over time, gather the humility to admit that there is sht that’s hard to explain, I’d think.... but, you certainly havn’t or it is this fake facade you’ve been putting up all day. Either way, I’ll see right through it...I conclude that you have no field experience and it is a waste of time to try and say anything to you Carry on, try and dazzle the Agon senior citizens some more with a few more of your simpleton charts.

I have address this before.

The next time a clinically DEAF guy plays a musical instrument, i want you to smack yourself on that low IQ CNS with that Audio Precision kit chassis repeatedly and try to add a few more IQ points to it.

So your eyes were involved in that experience. It makes sense, right? That the longer distance would make things worse.

Absolutely not....I sat in front of a couple of TAD monitors while a couple of snickering Japanese guys tweaked away behind me...All i did was time stamp what changed at what time....must be rough...being you hanging on to a sinad chart for dear life as your ship sinks.

if you study it, you will find that discovery begins with empiricism, our experiences of

As I mentioned earlier, I am a core engineer who got schooled by a few Japanese audio overlords. I sat at one of their facilities once and listened to a few iterations of some circuits. Guy varies the signal path distance... and the sound changes. A component he deems more thermally resilient vs non-resilient (external solution)...the sound changes . He had no engg explanation as to WHY himself. (Why Flippin why?).... But, he just knows...if I do this, it sounds like this or that, etc....years and years of accumulated empirical information by listening (in-house secrets, bizarre stuff) with no engg explanation. My closed mind opened a bit at that point.

Couple that with the fact that the human is a very malleable/adaptive creature...

There are DEAF musicians...clinically deaf (can’t hear nada) that play instruments. Can Majidimehr measure diddly on such a malleable creature? NO

Let us look at a less extreme case. I have been tied to a violin for 40+ years. I own a few different violins. I could record a progression on 2 different violins I own. You play it back and I will pick out which violin is which without blinking. Would Majidimehr be able to do so? No, he won’t, they will sound the same to him.

Deep went through a certain kind of adaptation with the sound of that instrument while Majid got stuck in a hole. They would all sound the same to him. His foolish self would want a blind test because he became the expert of my instrument after 1 hour of listening training he went through online on Harman’s website apparently.

He became the expert of me in 1 hour that took me 40 freaking years. Freaking amazing, ain’t it?

jasonbourne71, an ASR minion, chimes in with typical ASR minion snark.

deep_333 stated changes were/were not made that he could not see. Being able to see the TAD speakers is irrelevant to evaluating whether changes behind the curtain not visible made any audible difference. The ASR minions always find fault with any test, knowledge, experience, or enjoyment of audio that does not fit the ASR mold.

Anybody involved in the audio hobby in recent years very likely is well aware of ASR. Measurements have their place. However, there is no reason for the Audiogon Forum to provide free advertising space so Amir can cut and paste his charts, graphs and promotion of said material ad nauseum. Providing links is more than sufficient for ANY person leaving a post.

And it that quick moment of ASR advertising, captain feral copied and pasted a measurement on some TAD floorstander, it appears... Funny thing is...i was sitting in a building that belonged to a rival of pioneer/tad ( Pioneer, Yamaha, Technics, Den/Marantz..etc they are all considered to be fierce rivals over there). The monitors just happened to an older tad pro kit that this guy may have never heard of....

It was interesting...their "sound master" (poor translation indeed) picked 2 tracks of the 7 or 8 recorded tracks i had. He wouldn’t tell me why he picked those specific tracks (guy played all kinds of instruments). They were gracious enough though to let me use my own tracks that i’d recorded on my own instrument. They looped it and i just took notes with time stamps for a couple of hours. The guys had a whole work bench behind a curtain with all kinds of circuits (legacy, new sht whatever). Later on, they were explaining to me what correlated to changes made on their end (with their timestamps) against the notes i took down at different timestamps (with no visual)...plenty enough repeats in there..

Technics, Yamaha, etc would keep guys on their top end payroll (high job security n all) for decades if it was all baloney according to the clown and his minions with a AP kit....right? mmhmm...yep.

And yes, he wants a video (as if i owe him something)...i would want his hiney planted in my house...so i can telecast this clown to the world, show the difference in "listening skills"/ ability to pass blind tests (whoop di doo), etc between 1 hobbyist musician, 2 other pro musicians and 1 guy with genetically challenged ears who took a listening test on harman’s website for an hour (a self proclaimed sound master). He can hear an instrument in his 1 hour of harman website training better than 3 guys who may have collectively spent more than a 100 years in effort on their respective instruments apparently! We’ll find out.

It will be a few hours of 3 of guys laughing away passing blind tests as the minion leader sinks into an abyss. That would be time well spent, but, guess what? If you post such a video on ASR showcasing what a fool he is, he’ll take it down quickly and ban the guy who posted it.

 

Meanwhile, back at ASR.....

All the best,
Nonoise

🤣...i would have equated the ASR goon parade more with the necromongers, but, this works too.

A few years ago, Schiit decided to take measurements seriously, put aside their lousy audio measurement and buy an Audio Precision analyzer like I have. In less than a year, they managed to produce superb performance and price as good as Chinese companies.

Jason Stoddard (the Schiit): Capable of dev’ing amps, dacs, maybe a AP like kit, etc from scratch. IQ=170

Majidimehr: Aptitude levels restricted to reading AP manual, push button, spit chart, IQ=65

Majidi-minions: Write songs in praise of Majidimehr’s eternal glory, IQ = 25

Sonically, "State of the art" speakers need not be unreachable for dudes with thin wallets.

If you don’t mind the big n ugly, some sonic gems exist inside the relatively more expensive side of Pro Audio. To be fair, low aptitude extortion category "hifi speakers" can be ugly as hell too (look at wilson for example).

Guy’s started to tout the sterile class D again for low prices...You can get other better sounding topologies for lower prices too. For example, the Schiit Tyr can be endgame for all kinds of guys at around 3k. Sterile shrill class D + sterile Revel could launch you into a whole new level of sterile...you could quickly become a sterile ASR necromonger.

Somehow, i doubt the 100 dollar SMSL dac will clean the socks of some great dac implementations observed in technics, aavik, denafrips, mola mola, etc. But, i’m sure y’all will report back after you hear this 100 dollar miracle dac and start listing all your expensive dacs for sale.

Then comes the genius Bruno Putzeys who designed the Hypex amplifiers some 10 to 15 years ago. He put the output post filter into the feedback loop, and thereby nullifying its effect. He also added more gain which allowed it to in turn have more feedback, linearizing the response to near state of the art.

Sorry, but, I have heard this Putzey goof’s sterile sounding sht bro... It sounds sterile and lousy as sht...Ugh, i can only imagine this paired with your sterile Revel and what a world of sterility you remain in, unfortunately.

My condolences though (once you go sterile, ya never come back, i suppose).

 

Nope you said dynamics is how loud a speaker can play Amir.. that’s not dynamics. So dynamics don’t exist then? Your answers were very poor BTW.

An important component of "perceived" dynamics is dropping your room’s noise floor as low as possible. It will REQUIRE tailored construction for that purpose, solutions for hvac noise, treatments, etc. Otherwise, you could keep cranking the volume knob and only go deaf.

Another thing is when you have drivers that are designed to hit 130db without breaking a sweat, it may sound very clean and detailed (low distortion, no hint of compression etc) when you play it at 85, 90db. Mark Levinson’s M1 which is 100+ dB sensitive is an example and it is essentially a pro audio speaker. There are other higher end pro speakers that fall in that category, etc. It can add to this "perception" of dynamics. This guy wouldn’t have had such an experience with his 86db sterile Revel salon (just not that kinda speaker). He probably just cranks the Revel in a noisy living room and doesn’t know a whole lot.

Anything he doesn’t know doesn’t exist, apparently. That’s the definition of a backwardass scientist, engg undergrad (gpa=2.0).

 

again:

“ Surely you can hear a Cornwall has better Macro dynamics than a Harbeth right? Horses for courses. I’m curious all the different parameters you can measure bud.? And fast is absolutely a speaker attribute. “

“Nope you said dynamics is how loud a speaker can play Amir.. that’s not dynamics. So dynamics don’t exist then? “

also these were not answers to any level of any sane persons satisfaction.

 

1: DO YOU BELIEVE DYNAMICS IN A SPEAKER IS A THING?

2: HOW DO YOU MEASURE SUCH DYNAMICS (assuming you think it’s a real thing)

3: YOU REALLY DONT THINK FAST IS A THING WHEN IT CONES TO SPEAKERS?

Refer to earlier comment on how to drop the room’s noise floor to improve the "perception" of dynamics. Talk to guys like Dennis Foley (Acoustic Fields), Poes Acoustics, Anthony Grimani, etc about how to redo the construction, drywall, studs, hvac vents and so on.

And yes, there is very much a thing called a faster speaker playing the same notes. A few pages ago, I even hinted to the ASR simpleton how he would start to go about measuring it (atleast one aspect of it)

Such a speaker will let you perceive the dynamic contrasts better -> give you a better hint of the silence tied to the space in-between, your room’s low noise floor, etc when you’re playing music. For example, Borresen would fall in that category of speaker.

This simpleton will keep doubling down when he doesn’t know about something, keeping his minions in the darkness. I guess it is tied to his livelihood, pretending to be a know it all (so, it is what it is)..

the whole concept of stereo is an illusion.

The whole concept of stereo, a fossilized old technology is just dumb!

The whole concept of object based audio...or even a dumbed down something called BACCH that hasn’t been picked up by everyone is just a mind boggling denial of technological advancement and audio nirvana.

This brief transient lifespan is about exploring/experiencing new things (one would think), but, not when it comes to "purist audiophilia"... pure and goofy till the brief lifespan comes to an end, i suppose.

@amir_asr 

These 2 statements don't seem to lineup

"I listen to these DACs for hours and hours"

"I hear you but where do you draw the line? I listen to all speakers and headphones I review. I also listen to every headphone amplifier and portable DAC+HP amp I review. As you go further upstream, I listen less and less."

"listening is great. I do it in almost every other review". 

Excellent eye fellas...Fraudiosaurus Rex got caught again...🤣😁

There is nothing to discuss. You all need to start to listen properly without your eyes, matching levels, and producing statistically significant results. Otherwise the listening tests just serve the companies that want to reach in your wallet and lighten your load

Yes, yes, we know. Here’s a exceptionally high quality female vocals reference track tailor made just for you, something for all your listening tests and continued success. You could easily hear 0.000001% sinad differences with it, i’d think. Crank it up on repeat in your test garage and statistically significance will start pouring like the Niagara.

 

 

 

For someone who claims to have 2,000,000 visitors a month to ASR, Amir seems to have a lot of time and energy to devote to repeated postings in this thread on Audiogon. Somehow it does not add up, but he keeps coming back and arguing every point. He is always right, and always has the last word until somebody else tries to. It reminds me of the Eveready Bunny on Duracell batteries that just won’t stop.

For example, AVSforum hits close to 8 million some months and threw the feral ASR minion manager out on the road (banned his hiney into oblivion).

Agon hits around 1.5 million some months.

no big deal...

Automatic EQ systems do that by using a trick that relies on how much headroom your speakers/amp have. You pull the overall level down to the minimum of nulls (within reason). You then use PEQ with negative gain to fix the peaks. Result is flat response (or close to it).

Sloppy on all counts....but, I'll let you and the minions flounder in darkness on this one, lol.

I never engage during my music evenings : ) had to take a week break from amirs graphs and word games

The minions must have it tough when they go through his initiation program at ASR.
