How can he be "right" if he thinks that measurements directly correlate to sound. It has NEVER, EVER been proven. He made it up.....it is fantasy....so yes, he is wrong......and it is a lie to state what he says as fact......when it is not proven in any way. Liar, liar, pants on fire.....he he. I am sure he is a nice guy with some people......he did kick me off his forum. He is infinite spirit and totally beautiful.....but he has forgotten that truth. I hope he wakes up...this lifetime. I pray we all wake up to our inherent beauty. I love you Amir. We all love you......but, as they said is EST......."GET OFF IT!!!" Our "positions" about anything are what get us in the way of truth and love. There is only one attitude worth having.......Love and Gratitude. All other stuff in the mind is just blah, blah, blah.....including what is in my mind. We are not our mind.....we are infnite Love.....It is through the HEART that we find happiness.......The happiness that always exists (RIGHT NOW)......our very nature. We are all so blessed and loved.
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.
@rankaudio fine but that does not make him inherently wrong. Success is often accompanied by a large ego not just in the hifi industry but in general. |
In Amir’s defense, I bought a $80 dongle on a whim based on stellar performance reported in an Amir ASR review and that sucker lived up to the hype. It is as clean and detailed as pretty much any thing I have heard as expected based on the review findings. So there is something to what ASR does based on my personal relevant findings. I still like my much more expensive Chord Mojo, which got a much cooler review but the sound difference between the two are night and day. There is more to the world than ASR or any one site for that matter but I have no reservations recommending the site as a source of useful information to help make wiser buying decisions. |
Amir is right about tube gear. Many find that out the hard way. Some end up living in bliss. That’s not to say tube gear is nothing special. Just more YMMV. Not worth arguing about. They will always be all glowy and way cool looking, which matters. But that’s just me. Some of the best sounds I have ever heard has come from very expensive tube gear. Others from SS, often for a much more modest cost. |
amir_asrWhy in the heck should anyone buy a tube amp when even a good example has this kind of noise and distortion? As if to try to be hip by being contrarians, some audiophiles have clung to tubes, hypnotized by the glowing filaments, convincing themselves that they are hearing better fidelity. This and the rest of your post merely validates my point. You're just a condescending narcissist toward others opinions that don't jive with yours about tubes and an elitist. You don't have an ounce of humility. I'm not arguing against your measurements. You can measure until you are blue in the face because that's all you've ever done. It's you that's bothered by what others like listening to and that's why you purposely pull other peoples posts out of your own forum when they call you out on your errors. I've seen you do this time and time again in your own forum and other members have taken screen shots to prove you do this before pulling them down because they already know you will. What do you care if others like tubes? You feel a need to show measurements as some sort of validation that listeners shouldn't like tubes? Many enjoy tubes because they are colored. You have the audacity to tell others what they should and shouldn't like because your measurements show anomalies you don't like. Oh, they must be hypnotized by those glowing filaments. Well, so what if they like that too? I have a Klipsch The Three which you don't recommend. It sounds fine and it's fun for background listening. What? Now all the sudden I'm not supposed to like it because you did some measurements that don't jive with your ideology? You don't have to match gear if you don't want to. That's obviously not important with your methods according to you, so I'll buy a 3 watt tube amp on amazon and run it with my Magnepan's and complain to my audience about the results. You just get some sense of superiority in your mind by trashing on companies products with your measurements without proper context. In case you didn't know this, there are components that measure well that sound dull, boring and flat, hello? You're a real piece of work Amir. |
Well said and worth reposting. Reading Amir’s multiple posts this morning, I repeatedly wondered if humility has ever crossed his mind while proofreading. The picture of himself was the cherry on top - somewhat boggling why one would share, but mildly amusing at the same time. |
What does this have to do with audio reproduction, I could say satellite radio wouldn’t exist without the vacuum tube, which would have a closer relationship to audio reproduction than your example. |
Amir is being truthful? Amir is demonstrating exactly how much he doesnt understand. Certainly less distortion is a good thing but not if in order to get lower distortion you sacrifice other aspects of reproduction. Tubes give you better linearity, allow for a much simpler circuit and have better low level resolution. So they measure higher in distortion but are more satisfying and accurate in other ways which may not be measurable. I dont care how honest a person is if they consistently demonstrate not only a lack of fundamental understanding but also a refusal to acknowledge the complexities present. The dumbing down of a complex issue simply so he can create a more defensible position does no one any favors. Amir doesnt want to help he wants to divide.

ASR seems to me to be a place where hoards of people with cheap equipment are so desperate for validation that their $300 "insert piece of equipment here" is just as good as a $6000 "insert piece of equipment here" (that they’ve never heard for themselves, mind you), that they’ll resort to personal attacks. Amir leads the show over there and I find it rather appalling and ignorant. Not for me, thanks. If that's being a "cry-baby", well....I guess I've been called worse.
This is the worst of ASR, but not the whole of it and you know, it's the internet. |
Against my better judgement I will reply to this train-wreck of a thread. "Amir was being honest with the measurement results he obtained. Science and its engineering applications are based on measurements." I firmly believe this to be true. However, I also believe there are intangibles when it comes to audio and its reproduction. In other words, measurements don’t tell the whole story of how a certain piece of equipment sounds. "OMG they gang up on Amir because he’s being truthful... what’s wrong with these people acting like bunch of "cry babies"." Amir brings it upon himself. I find his responses to be childish insomuch that he portrays an attitude of self-righteousness and condescension towards anyone whose opinion differs than his. My advice is to think and listen for yourself. I think you’ll hit a point in your audio journey where you realize that one guy doesn’t have all the answers. And if they tell you they do....probably time to move on. ASR seems to me to be a place where hoards of people with cheap equipment are so desperate for validation that their $300 "insert piece of equipment here" is just as good as a $6000 "insert piece of equipment here" (that they’ve never heard for themselves, mind you), that they’ll resort to personal attacks. Amir leads the show over there and I find it rather appalling and ignorant. Not for me, thanks. If that's being a "cry-baby", well....I guess I've been called worse.

Sure. The transistor is one of the most critical inventions there is. This site would not exit, nor the Internet without it. It drastically reduces power consumption, shrinks the sizes of components and provides incredible fidelity that no tube product ever produced. As if to try to be hip by being contrarians, some audiophiles have clung to tubes, hypnotized by the glowing filaments, convincing themselves that they are hearing better fidelity. So here I come and show how much dirt the tube amp is throwing in the signal. And that for this privilege, you pay boatload of money to boot. Any rational person would say what you quoted. It is like building a car today with a steam engine and claiming it goes faster than a Porsche but when the data comes out that it accelerates at 1/100 of the rate, expect praise to be poured over said steam engine car! Granted, that example was that of a better designed tube amp:
This is how it performed:
Why in the heck should anyone buy a tube amp when even a good example has this kind of noise and distortion? Again, do you not have any respect for the work of the artist and engineers and produced the content? They didn't use this amp to produce the music, right? Why do you want to serve their food in such a dirty dish?
Oh. That is like saying this is a great car but you better weigh less than 100 pounds to drive it! It is not my job to "match" gear when I can buy huge number of other amplifiers that don't need any matching. How would matching reduces its noise and distortion? How do you know the impedance of the amp and the impedance of the speaker to know how to match them? Answer: you do that with measurements. But again, why, oh why? There is not one controlled listening test that shows any of these tube amps to sound better. All of the fans and companies producing tube amps have not had the wherewithal to produce just a single, ears-only test, to show that they sound better. If it is so easy to tell they sound better, why don't you produce this simple test result? I tell you why: because you won't find the answer you are looking for. Tube amps at best have harmless distortion. At worst and in many cases, have clear audible noise and distortion. In the case of tube amplifiers, that is trivially shown as they run out of power and distortion like hell. You want to believe in fantasies and magic? Do that. But don't tell me this picture of fidelity:
Or you could have this:
All of the above are with dead easy to drive resistive loads by the way. And at just 5 watts. These tube amps are pure noise and distortion generators. They are an insult to decades of progress in engineering to resort to them for anything other than nostalgic look.
|
amir_asrYou can still "love" said tube amp but don't go making an argument out of it. It doesn't bother me one bit whatsoever that you don't like certain tube amps, that's not the issue. I have a couple of friends who don't either and it's fine, there's nothing wrong with that. Some people like chocolate ice cream while others like vanilla. BUT, when you purposely trash products by "misrepresenting" them which you obviously seem to enjoy doing, then yes, it causes arguments. You have consistently misrepresented many companies and try to act nice and rational when in fact you are just patronizing others. All that rational demeanor is a load of nonsense. You can still be rational and condescending at the same time and that's exactly what you are. I flat out don't like you and I'm not gonna candy coat it. Look at this response from one of your members to understand what I'm saying. You don't care as long as you have your cult following. Great review @Amir, I’m going to use this as reference to not buy valve gear…..ever! Does that kind of response sound like you are educating others? I politely asked you if you could simply clarify my questions and you would not answer. You simply refuse to match gear properly. How do you intend to listen to a tube amplifier properly if you don't use proper speakers for them? Of course it's not that much power, because you used it with some inefficient Infinity speakers. I had to find out myself from another source because you refused to answer. |
The bottom line is that the only way to know..."if the signal comes out unmolested" is to listen to it.......measurements with out listening is insanity. How can you know how transparent a component is (has no sound)....unless you do listening tests. You cannot assume your measurements mean anything unless there is actual LISTENING Tests that prove that your measurements mean ANYTHING at all. Amir does not know sound.....he just knows how to read his meter.....and assumes what the meter says somehow correlates to sound.......a false conclusion that is NOT based on empirical science......as I stated before ASR stands for Amirs Seance Reviews.....for he is predicting things from the other side (the other side of reality...generally called Make Believe)......When you make up stuff that is not proven and call it truth.....it is called lying. Should be ANSR.....Absolutely NO Science Review. We are all beautiful and worthy. However, if you make up sheet and call it truth then you really do not love yourself or anyone else. You are not living your highest potential. Truth is what you experience.....with all your senses (including intuition and natural knowing). There is nothing Natural with what Amir is doing......but is it natural for humans to digress into their ego and defend over and over what they say. There is very little chance that Amir will change his mind about anything from whatever I say or anyone else says. This is how stroing the ego is. It would rather be DEAD right than admit to being wrong. I hope he does not take this lying game to his grave......but we have eternity to get it right (there is no death). I just want to see everyone happy and living in truth.....right now. We choose every second....to either live in love or to be right. Choose wisely grasshopper. |
mahgisterI must say, you certainly raise excellent points. Really enjoyed your constructive post. Thanks again for sharing that. |
@amir_asr distortion numbers are important, but so is linearity, and as far as I know triodes are the most linear devices without feedback. |
@amir_asr Its fascinating how blunt your words are.I would write the same even if you have substituted 'tube amp' for 'ss' one.There is no place for generalization or exclusiveness of any kind, in hi fi. There are many people here, constructors, with vast knowledge and experience who have probably forgotten more than you will ever know and never read that any of them was so pretentious and tried to pronounce his conclusions or beliefs as a final and only truth. For doing something like that, person must be at least deprived of social intelligence or have delusional impression of his own importance. Either that or you are just trolling. For your own sake, I hope its the latter |
I both own tube amp and have passed countless blind tests:
Neither do I. I don't care what is inside your gear. All I care, and so do many of your fellow audiophiles, is that the signal that is sent to it, comes out the other end unmolested and as such, respects the content as authored. A tube amp that has copious amount of distortion and adds coloration due to its high impedance, doesn't do that. You can still "love" said tube amp but don't go making an argument out of it. |
I am very far myself from techno-cultism pervading the engineers crowds especially in A.I. I dont confuse not reduce wisdom and knowledge. I dont reduce knowledge to science , and i dont confuse science with technology. and I dont confuse technology with techno-cultism religion. But hearing studies are sciences also not only emotion... All my audio system is stunning at peanuts price because i learned and study acoustics basics... Acoustics measured parameters with my ears or not, matter in audio experience way more than ASR fetichism of electrical engineering what we evaluate an audio system"room and even with a piece of gear ... Thats my point of contention with Amir... Calling him names is childish ...😊 Emotion is what i felt with my stunning system each day thanks to acoustics basics... I tuned my resonators and diffusers by ears by the way because the tools needed to do it will cost more than my system price and will not do better ...😊

Emotionless listeners have the same MO. They’re mostly civilized and rational because they have no emotion. I judge music and sound based on inner emotion. If I want civilized and rational, we’ll have plenty of that when artificial intelligence/unintelligence takes over. Why do we watch movies that have emotion? We watch them to be entertained because if actors didn’t act with emotion, they would be boring, like robots. You see, we live in this day and age where people think they need to know everything. If I’m watching a magic trick, I don’t want to know how it’s done. I want to be fooled, I want to be entertained. What is sound, what is music without emotion? Singers sing with emotion. That’s what makes them great. What the heck are people listening to these days? Amir needs a chart to tell him what sounds good? He needs it because he doesn’t know himself what sounds good. Amir hates tube amps because they measure bad, yet countless audiophiles love tubes, myself included. The guy wouldn’t pass a blind test to save his life. He needs a chart to tell him.

My youtube channel was started way after I created ASR by user requests. Like ASR itself, it is not commercial. Has no monetization, sponsorships or ads of any sort. In that regard, I am NOT like any other audio youtuber or most youtubers. Mind you, with nearly 50K subscribers, there is good money to be had but I refuse to go there. So whether one person views my videos or a million, it doesn't make a difference to me.
A lot of my videos are educational which by definition don't fall in that category. I actually don't publish many product reviews in youtube but when I do, many are positive and without controversy. Here is a combination of both where I talk about performance of Genelec 8050B speaker and how to read and understand speaker measurements:
Videos are recorded live and uploaded with no edits. No fancy purple lighting. No clickbait titles, etc. The only reason to dislike them would be because you don't like it when reliable data, science and engineering speak. But yes, there are a number of reviews showing poor performing gear. Compare that to reviews on audio channels which they don't dislike anything they review. As long as they get free loaner gear to test and drive traffic to their channel, the product is the best they have heard, punches above its weight, has darkest background, widest and deepest soundstage, sound analog, etc. In other words, you can get an AI to write the reviews!

I know how you feel... I was served the same medecine by some ASR zealots when i posted unusual experiments propositions with Quartz and Shungite.Then i quitted ASR under sarcasms and not very polite comments about these experiments propositions .. And i decided to stay here 😊 I only read time to time many excellent threads on ASR .... But i dont think Amir will go so low himself attacking people opinion, he is enough confident in himself to act civilized and rational with his own arguments .. But ganstalking fanatics exist even here ... We must pick our language carefully then... I dont think Amir is a "narcissist" because his hearing theory is superficial and subordinated to what he measured in a short set of measures presented as the main element to pick the right gear piece .. ...😊 i apologize if i reacted and gave my opinion on your post but ... My best to you sincerely ...
|
mahgister
I agree with you, however, you should see what he and his henchman do to others who say anything that doesn’t jive with their cultist methods or how they sensor people who question their methods. Amir deserves everything that was said to him. |
I dont think that it is good politic and proof of understanding to attack any character or person here instead of discussing his rational arguments...
I myself discussed for many days already here with Amir and he never attacked my character. For sure some posters on ASR as in Audiogon can gangstalk someone and many had attacked or mocked many people here or in ASR . But Amir was and is a gentleman...😊 I disagree completely with him about the order of the factors importance : hearing theory and experience must rules gear measurements not the reverse. And anyway physical speakers/room/ears acoustics measurements takes the cake over some small % differences of some cherry picked electrical tool measures applied to one piece of gear design, out of any specific system synergy and out of any specific room acoustic for no specific ears ...
Anyway only rational discussion makes us different from raging apes..😊
myself i think the same as
|
I do not agree with Amir's measurements are the end all point of view. This is because I have purchased the best gear as stated on his site and compared with other gear. However, I do find his site and tribe useful for me to figure things out. Some gear that is praised to the hilt on this site was also not preferred by me. I have learned to understand the sonic preferences of A'gon posters. That give me some context. I will hear everyone out on their audio experience since it gives me more data points to figure things out on my own. |
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" Why then he bothers to do the measurements? Isn't the perception behind the whole idea of the sound reproduction? I think these are rhetorical questions. @alexatpos "I understood that any other conversation is pointless" exactly
|
He's a YouTuber who uses this site to promote his, just as numerous others have done here before him. They all rely on controversy and drama to whip up enthusiasm and if there's not enough excitement to generate the clicks they'll invent their own conflicts. Another common YouTuber technique is to cloak oneself as a savior - a protector against a corrupt industry, snake oil, and unscrupulous dealers. Those that fail to embrace the savior are thus "afraid of the truth" or hopelessly deluded. Those patterns are really obvious.
|
Personally, I have never been bothered by Amir's conclusions. We have exchanged few notes here, but after I read that he do not 'hear' ('believe' , 'measure' or else) difference between various different cables, I understood that any other conversation is pointless. On the other hand, I have many audiophile friends, who have very different 'standards' about hi fi than me. Should we all start 'fighting' with anyone who believes or does things in a way that differs from ours? I believe not. So, instead of trying or pushing him (or anyone else of that matter) away from these pages, I guess the smart way would be to choose conversations where you can actually learn or share some information with people whose opinion you care about. The rest is just a waste of time and energy. He will not change his point of view and neither will anybody else who has a different one. Him, being pretentious a bit, should not be so annoying for anyone to loose good manners about it |
Amir it is time for you to exit this thread. With each post you dig your grave deeper with yet another nail placed in the coffin lid. You are not doing yourself any favors. When I briefly checked your reviews very few high end companies actually send you their product to review. A bunch of mid-fi with customers sending you, apparently, the "higher end" stuff. At least on this site, your 15 minutes (being generous) is up. Your lack of understanding is pitiful.
|
@amir_asr Off topic? Why, just checking your qualification and credentials. Did you mean destroying shareholder value along with other MSFT VPs until you finally got fired, oh, sorry "retired". Stock was only going down back then. But I am sure you were paid really well. But not engineers who actually did the work. All while Nelson was making real gear. Not "measurements". "Once it a while" according to time stamps means you jump back here as soon as someone mentions you. On Friday night LMAO.
|
Why do you trust anyone? You are buying a product, not the person. It is not like Nelson is going to come to your house with that amplifier. He has built a product that competes with thousands of others. He doesn't provide an ounce of reliable information as to why his amplifiers are better sounding. He wants you to believe that they do and you do. Countless fellow audiophiles are yours who read ASR want reliable information and measurements give that to them. They also want to learn the underlying science and engineering which again, ASR provides. In contrast, you seem to be wanting people to buy products just because of someone's reputation. Which you are welcome to do but then don't ask me to tell you who you are.
You are in a thread that is specifically about ASR and how a company attempted to shut down my evaluation of their product and that of another reviewer. Instead of commenting on that and defending the right of free press, some of you have drifted into misinformation and insults about me and work I do. So once in a while I answer when I get a notification about this thread and me being mentioned.
On your first question, I bought a great system some 15 years ago before I started measuring anything. The most important part of my system is Revel Salon 2 speakers. When John Atkinson of Stereophile was asked which speaker he likes after hundreds he had tested, he said Revel Salon 2, mentioning that "he almost cried when he had to return them." My DAC has since been upgraded from Mark Levinson to Topping. The amplifiers remain Mark Levinson. They produce 500 watts into 8 ohm and nearly twice as much into 4 ohm. I need the power to drive the rather insensitive Salon 2 and other speakers I test. Had I not own them, I would not buy them however and instead, would get a Hypex based amplifier. Finally, on Microsoft, products my team designed have shipped in billions of products and I don't just mean Windows. Whenever you watch video and your bandwidth drops and so does the fidelity of the stream, that is technology we invented in the company we sold to Microsoft to adapt stream quality to bandwidth. We were pioneers in streaming, for which, I was proud to receive the 3rd Emmy award for technologies developed in my team:
Any more off-topic comments you have that you want me to address? |
| Post removed |
@amir_asr You can be measuring to kingdom come while we will look at your charts, shrug and go buy Pass Labs or BAT and not your beloved Topping. Because you "have been measuring" while Nelson and Viktor built tons of gear people love, buy and keep for years. For some reason I trust their engineering chops more than yours. Why is that? Why are you even here? Are you yearning for attention and confirmation of your "achievements"? Maybe you instead should star thinking why is that components with crappy parts and that are not even soldered right measure great - but sound like junk (which is what they are). BTW, in your personal gear you list Levinson and not your "top measuring" gear. Why is that? How do they say at MSFT? Eat your own dogfood? Oh and what were great achievement of "Digital Media" at Microsoft? Like... none? Refusal to support lossless perhaps? Inability to even make a decent media player? |
It would be a HUGE compliment to say I am charismatic on camera!!! 😁
I am nearing 2,000 measurements of audio gear. Large number of major companies read ASR and participate in it. The level of scrutiny is off the charts. Despite all this, the number of times I have had to re-address a review can be counted on one hand. The reason is simple: I run the same set of tests on every product category. The tests have been battle tested and blow away the meager or non-existent measurements from companies. I have also been measuring audio gear for 30+ years now. I am an electrical engineer and put myself through college repairing thousands of audio gear. My professional experience has spanned all aspects of modern audio technologies such as streaming, networking, operating systems, embedded development, chip design, PCB and analog layouts, safety and regulatory issues, user interface, performance, to name just a few. This doesn't mean I know everything in the world but it does qualify me quite well to be doing what I am doing. When CEO or a company that has been removed from design for years claims that their product does X, when I measure it and it does Y, compared with my knowledge of the design and technology, then you should pay attention. Don't be dismissive and say the opposite.
|
You say that but then post a video from the company and not my review and responses. If you watch them, you realize it is Paul who a) hasn't properly measured the product to see if it makes any difference in the output of your audio products and b) doesn't know his own product has current limiting so reduces amplifier performance. I have done no less than three videos on this:
Paul is charismatic on camera and does have good knowledge of audio. But be careful in believing everything he says. Above is a great example. |
Nothing wrong with longer ground connection. Or requiring more force. The problem is having a jacket around the plug that slides forward as you push it into the socket, making it not possible for all the pins to make a connection. This caused the cable to not even be functional until I realized what was happening! It is all explained in my video:
|
Well, I just watched pieces of few ASR videos. Let me tell you, it was not easy for me. The engineer does not how to insert the power cable into the socket (needed "fifty times greater force", must have measured it obviously), doesn't know that ground pin is longer then blades on audio cables. Just two items from my laundry list. It was really amazing experience watching it. I have to lay down now. |
In my experience discussing with him for 7 days here , he confuse sound quality and electrical measures of the gear for 2 reason: --- For one, it is his own selling pitch , he sell his site, products and expertise,,, ---The second one is he think acoustics is room acoustic.. Even if he know the difference between acoustics and room acoustic he had no idea what we hear when we hear a qualia and a physical property of the vibrating sound source in our own non linmear time domain because for him the ears is a deceptive tool compared to his electrical devices, period. ... It is science : hearing theories are the core of acoustics... He know nothing and dont want to know nothing about that ... Fourier maps is the territory for him . Period... But sorry Fourier maps are not the acoustic human territory ...😊 it is easy to understand the huge difference if we study.
It is an engineer in software and a seller and a gentleman ...😊

I do check ASR measurements, and I thank them for providing the service. However, this is the task for @amir_asr to figure out why some gear measures better than the other while sounding worse. Or that it measures great while consisting of crappy parts - Topping teardown is available for anyone to see. ASR community reminds me of people who try to prove their point about sampling rates by quoting Nyquist theorem. While knowing little what does it actually proves. Or the difference between theory and actual implementation. If Pass Labs measures not to Amir’s standards, perhaps Amir should write to Nelson Pass and ask. Or ask Viktor Khomenko in forums about BAT. I’d love to see their responses. For some reason I trust Nelson with decades of products that people love and keep more than some Internet forum owner with a scope. |
