The Law of Accelerating Returns


I totally agree this letter from the editor of A-S.

It makes sense if you have a $10,000 high quality integrated and stick a   $500.00 TT with a $300 phono section, a $400,00 Topping DAC and stream through your phone you will never know the real potential of the $10K integrated. And don't get me going on speakers. 

This article makes total sense but one must live within their means. 

No you do not have to spend a left lung for great sound but it all needs to be balanced.

Actually, I go through the upgrade process about every 7 years. In the beginning it took a couple or more years to get through the process… then I would just really enjoy the music for years until I could afford a substantial upgrade. 
 

Now my upgrade cycles are pretty short as I know what I want, know how to read reviews,  know how to pick the right sounding peripherals. Then back to years of amazing satisfaction in just enjoying the music. 

@ghdprenticeThe incredible positive reinforcement I have received by attention to detail and paying attention to what stuff sounds like has been so rewarding it is amazing.

I can agree.

I greatly enjoy exploring and auditioning fine audio gear, but I’ve found that, after the do-diligence of matching components, speakers, cables, etc. and tweaking in speaker placement and room fixes, I need to make myself just sit and listen to the music and performance of a variety of my favorite music. Then, when the music, the vocals and all else falls into place and everything sounds and feels right, I need to allow myself to spend more time enjoying the music and less time chasing my tail for that elusive something more

We, more often, need to concentrate and be pleased with what works for us and not worry too much about what it takes to please someone else......Jim

I have to attest to OCD coming with the audiophile affliction in my case. I am not a perfectionist… I am at the other end of the spectrum. I have a perfectionist friend… who has had his life destroyed by it. Not a fan. But audio… The incredible positive reinforcement I have received by attention to detail and paying attention to what stuff sounds like has been so rewarding it is amazing.

 

I've never forgiven them for their 4-part series on digital audio where they reported the original file on the hard drive sounded better than a copy on the hard drive.   
 

I have noticed many things in digital audio That doesn’t make sense but nevertheless are audible.  A file played off my hardware raid sound better than the same file copied onto my software raid.  And Jriver is set to memory play.  Makes no sense but it’s there. 

I Can't quite determine if OCD is a pre-requisite to becoming an Audiophile or is an affliction brought on by being one.

Not that I don't believe in matching components and speakers to work together; not that I don't believe in proper set up of room and components, but sometimes, even when we think we have everything sounding really good, we can't just enjoy the music - we have to fix it till it's broke and then start over, or at least find the next new fix. Usually the more expensive the fix, the better we feel, at least for a while. 

Although reviews and articles on audio gear are sometimes interesting and informative, as far as the AS article, as well as other professional articles and reviews, it's important to consider that their primary objective is to push and promote expensive audio gear - that's what pays the bills.......Jim

 

Underwood HiFi has terrific products priced well below the big name brands. Priced for the blue collar who loves excellent playback.

Their Voyager 350 GaN amp is amazing, as is their Core Power products. I also have their Emerald Physics 3.4s, which are out of production (sadly), but blew away my Magnepan 3.5Rs

Don't worry Jerry I hear Ukraine is going into the scrape Iron business and will become the new world leader in scrap Russian iron for building a BETTER Ukraine.  After they refine the crappy alloys used enough, they could use them for new toilets and sewage line infrastructure. You know, "here's thinking of you" FLUSH!  

Very few people can beat my sound quality/price RATIO... 500 bucks for the system and peanuts cost for the room..

But no one take almost 2 years to tune his room ( 100 resonators and diffusers) many months all the day listening...It is also a PRICE to pay...

 

And i dont have an opinion, only experience and experiments with acoustic huge power for improvement WITH A CHOSEN SYSTEM...It is science easy to verify that acoustic matter the most not an opinion taken from a hat...

But acoustic dont perform miracles and never transformed my very good Sansui in a Berning superior ZOTL... Only Christ make bread with stones...

But i dont give a damn about the superior ZOTL now, my Sansui i can live with it easily...There exist a minimal TRESHOLD of sound quality with which anybody can live without being frustrated...It is WHY acoustic can teach us something no upgrade will never teach us...

Helmholtz founded modern acoustic thinking listening to his resonators and he founded modern psycho-acoustic thinking about the way the ears/brain can take notice of the frequencies differentials ...

And yes cheap is too more money for me , cheaper is better ...

Anyway acoustic dont give a damn to the price cost of materials, only about their location, dimensions and ratios and acoustic content...I even used empty toilet paper rolls by the way... 😁😊

Who will dare to laugh? i will laugh the last...

Sorry to put the point over the right letter...

😁😊

Acoustic optimization is the law ...

By the way the fact that a piece of gear upgrade could GIVE more resolving sound frequency-wise is not a proof that the sound will be IMPROVED at the end ... In acoustic frequencies resolution is one aspect, phase count also and timing, and ratios and balance between reflections/absorptions/diffusions... And the pressures zones distribution in the room, and more than that the way each one speaker will adress differently each one ear matter MORE than the difference in resolving power between a SANSUI amplifier and a BERNING ZOTL amplifier... Then acoustic rule over most upgrade choices, if what you already own is already very good...

This is not my opinion, this is experience and science...Sound come from the speakers/room not directly from the amplifier or from a dac...The dac-amplifier gear convey the information with variable success yes but they cannot translate the information in sound , the speakers/room/ ears/brain system do it....Then acoustic/psycho-acoustic explain it to us...

There are no experts only opinions.

They are like what?

Cheap is cheap though.

 

 

TAS is the Fox News/CNN of audio publications. A clear agenda outside of reporting on audio. I've never forgiven them for their 4-part series on digital audio where they reported the original file on the hard drive sounded better than a copy on the hard drive.   

"Just the other day I replaced a 1.5m interconnect between the phonostage and linestage with a more expensive model."

More expensive?  It MUST sound better!  I actually insulate my cables with $50 bills.  The $100 bills were a mismatch with my amp. I can't wait to buy a "more expensive" amp so that I can re-line my cables with the hundreds! 

When I read the article I had quite a laugh. We have to remember that TAS serves an industry based on the simple assumption that spending more money gets you better sound. Anyone, even multimillionaires, want to think they are receiving good value for their money so the theory of "accelerating returns" fits right into the agenda.

Wonderfully and simply stated.

I agree! Be careful when picking your experts.

Kinda like getting your news from the MSM or Fox.

One point of view.

Bit it has people talking about other things than Russian Tubes. 

Speaking of Tubes I am listening to them. Enjoying an ice tea.

@jpwarren58 Headphones. Or hang a bunch of foil and crystals. @mahgister swears by the.

No mahgster I am not saying they do not work. But if I did that my wife would have left me at the Poland Ukraine border 2 weeks ago…..

That is not flying here.

 

I perfectly well understand...My wife dont want to touch my audio room....I manage the necessary cleaning ...She hate my room but my better review was his: "it is very good sound and it is suprizing in this mess of a room..."

😁😊

By the way my most important tool are Helmholtz devices and methods with resonators and diffusers...

Not stones and minerals, nor Schumnan generators nor ionizers all of which worked BUT are minor improvement compared to acoustic treatment well done and acoustic mechanical control especially...

My 8 headphones are in a closet now guess why ?

But the truth dont change with our spouse status , acoustic is key...

My deepest respect to you and your dedicated wife...

The alternatives or choices for most of us is not ultra high end versus low cost design...

Even Helmholtz method will not change my very good Sansui AU 7700 old design in a Top Berining ZOTL amplifier...

But for all people with audio system at any price the main MULTIPLIER of S.Q. is acoustic and psycho acoustic methods...

I used Helmholtz method which adress the action of resonators and diffusers...

I used Classical room treatment too where the SURFACE balance between absorbtion/reflection/diffusion is key...

I even used "tweaks" which work well like Schumann generators at low cost and ionizers...

But none of that will transform the design quality of my Sansui in a ZOTL...

But give me a ZOTL and i will certainly used acoustic and all the other controls i already used but in a complete different way accordingly to the meeds of the new components...

And i prefer a sansui in a controlled room anyway at many costlier design in an uncontrolled room...

 

In a word if like me most people you own relatively good component but low cost

one it is better to use acoustic method than buying an upgrade piece... But we are not all in the same situation... i own a dedicated room, most dont... I dont need esthetical design, most need them...

Then my experience teach us something that cannot be applied for everyone needs and everywhere...

One thing cannot change, acoustic is the key to Hi-Fi... Not upgrading generally ... Especially if we want to live with a good ratio S.Q./price...

No expansive system can fic a room, and anyway any system at any price will benefit from acoustic...

No one sell a ZOTL to buy a Sansui with a "tweaks" for sure though... 😁😊

But i prefer my Sansui in a controlled room to a ZOTL in an uncontrolleed room...

I hope i have been clear...

No speakers beat the room said an acoustician...I dont remember his name...No amplifier too...But no room will make a bad design a better one...Acoustic method OPTIMIZE the working of what we already have, bad and good component...

The effect of acoustic is huge but only Christ transform stone in bread...

 

 

So can an uber expensive system fix an average, flawed room? If the room cannot be adjusted then what other choice do you have? Tweaks or better components? I choose better components. And how many sell expensive components after comparing to a stone or a resonator or liquid plasma cables?

Well said...

And not a word on the HUGE change coming from acoustic treatment and control... For sure...

Who want to know that a 100,000 bucks audio system is not enough to reach a hi fi sound most of the times...

 

Helmholtz method is the key... Acoustic is the door...

I can accept it costs more to produce better performing components. But there is some voodoo physics in "high end" products. One example is speaker cables costing tens of thousands of dollars. The issue of skin depth attenuating high audio frequencies is an example that can be easily calculated. A pair of 8 gauge solid cables has the resistance changing from 0.005 Ohms for DC to 0.01 Ohms at 20 kHz for typical lengths. This in series with 4 speakers attenuates signal voltage by less than 0.01 Db. Cable marketers caught in this junk science lose all credibility for me. There are other claims: differences in signal path length of a few millimeters at the speed of light smear the sound and stored static dipole polarization in loudspeaker insulation can be tested by putting the insulation next to another cable with the speaker disconnected. The first cable is connected to the speaker and not to an amplifier. Such stored dipole energy from one insulator should be possible to hear in the connected speaker if insulation were an issue. It does  not. 

 

Having read the editorial, I am not sure what the point is.  It seems to be arguing simultaneously that smallish upgrades may unlock the Pandora box of beauty previously concealed, and also that one shouldn’t hesitate making an huge upgrade to one end of a system even if the rest of the system isn’t in the same league.  To the first part my response is “Duh”…hasn’t we all had that experience?  One small change and everything seems to snap into focus? And to the second part, all I can say is  that isn’t my experience.  If one link in the chain severely hampers everything else, it doesn’t matter what you do with everything else, you have to fix that one issue 

@mahgister gotta disagree. The technology can easily be the bottleneck once the acoustics are addressed properly.

I never say that the technology has no bottleneck ... I say the opposite... read my post another time ...

An integrated amp however means less technology integration to get right. The experts have addressed that for you and the product solution is solved for you regardless of room.

You are right this time too... But you miss the essential  point... Any technological upgrade fpor the better will suffer the lack of acoustic control and will work UNDER his peak potential level unbeknowst to you especially if you come from a lower design to a better one, you will appreciate the improvement but you will never know that this same system is able to deliver way more in a controlled acoustic environment... This is my point...

I done negate that any technology can be replaced by a better one... I negate that a system/speakers will replace by itself room acoustic... In the future with an A. I. expert system integrated to the room yes ....

My point is simple, we cannot judge all problems amd limits pertainig to a system/speakers without a room adapted to it... Simple... This does not means that you are wrong... This means you miss the important point to judge any system limits : acoustic... Not upgrades...

@mahgister gotta disagree. The technology can easily be the bottleneck once the acoustics are addressed properly. An integrated amp however means less technology integration to get right. The experts have addressed that for you and the product solution is solved for you regardless of room. Now you can deal with the thing unique in each case which is the acoustics of the room and integrating just the speakers to amp and room. Much easier to get right technically. All electronics are different still however so even an integrated amp may still be the bottleneck in the end. At that point if it matters you want a better integrated amp. It all matters. Just a matter of how practically one goes about getting all the parts of the system right. The complete system includes the room and ones ears which are always different in each case. Cheer!

It’s true that if the system is in good shape ie no serious bottleneck then one is free to deal with the room.

Not exactly mapman, no...An integrated solution will have his own bottleneck...No system is perfect but all system at any price can be lifted out of their bottleneck to a new bottleneck yes... But for example my actual system room is out of my past bottleneck, in a new unperceived bottleneck...I live very well with it why?

Because when we reach a certain sound quality level, we know what will be the cost of a real beneficial upgrade, only at this time we can know it... mine will be from my 500 bucks system going to a minimal 10,000 to 15000 bucks system... why i dont want to do it? not only because i dont have the money but i dont need it really... Pianio sound fill already my room, my system/speakers beat already my 8 headphones... there is always better but i am very pleased... My soundscape is the best i ever listen to anyway...

 

How can you became conscious of a bottlemeck inherent to the system in all case, especially with a  already good system like the one i own ?

I was never conscious that i listenedc in his botlleneck in the past  BEFORE i take control of the room ... why?

Because any system has his own limitations and bottleneck, then how can you know them and detect all of them in a nude room without acoustic control of any kind ?

i bought my system , i was happy, but not COMPLETELY  satisfied without knowing why...I cannot put my finger on anything...I though that all was right and at the same time all seems very  limited: timbre,imaging, soundstage etc 

Some bottleneck was there but not manifested openly, i was sensing that something may be lacking without the faintest idea what it is and how to adress it...

This become gradually clear when i PASS OVER THIS bottleneck with an improving acoustic, which means i become conscious of  where i come from and where i was going...

It’s true that if the system is in good shape ie no serious bottleneck then one is free to deal with the room. You can hire experts for that as well or most people can just have at it themselves with some good references for guidance. It’s another advantage of an integrated solution. One can then focus on speakers and acoustics better and acoustics always vary by room.

 

It is not false for sure, but this hide the essential...

The greatest bottleneck is our own room acoustic and more than that our own untrained hearing with acoustical experiments... The main bottleneck is our brain...

An acoustic concept is not an abstraction, it is a reality that must be concretely listened to...

A system or several pieces of gear exist in a room for the ears, and the bottleneck of the system must be manifested IN  the room where it is well or not well embedded to the ears and for the ears ... To understand the true specific nature of this gear bottleneck we must understand acoustic first... If not, we are embarked in a carousel of upgrades most of the time meaningless.because we are unable to listen to this gear at this optimal working peak anyway... It take a room adapted to the gear and under control for that....

Every system has a bottleneck, ie the thing that limits performance. It’s just a question of how much it matters.

 

The time I spent learning about room acoustics has been the single greatest enhancement of ALL the changes through the years of listening.. It was also the least expensive..

 

Same here...

All the rest is gear conditioned mass ignorance and selling technique...Not because all gear are equal, they are not, but matter way less than acoustic...

But even acoustic seller sell ignorance or easy to made passive costly material...

An acoustic tuning and control is too complex to be sold at low cost...

We must do it ourselves..

But it is not very popular to say to people that 20,000 bucks system or 100,000 busks one that did not matter the way they think...

Audio system are like woman, most dont want to take the time to learn them, plug and play, plug off... This is audio for most...

And their brand name is proof enough for them that it is good...They think that they know how to hear but hearing must be learned like any acoustician or musician know already...

The truth is not popular and science either is not... propaganda and publicity are more easy to swallow...

You know all that already ...

My deepest respect to you...

 

Every system has a bottleneck, ie the thing that limits performance. It’s just a question of how much it matters.  Can be very hard to determine with hifi gear.  It takes a lot of work regression testing ie changing one thing at a time and comparing.  Even then it is a subjective comparison and not an objective one so results will vary FBOFW .   It can be a real exercise in futility in some cases to get it all truly optimized for best technical performance .   That’s what engineers are for!

New integrated amps and all in one units from reputable makers are a great way to avoid serious bottlenecks at a price point by letting the experts integrate things for you properly. Integrated amp technology has come a long way. There is probably one out there to satisfy most anyone. Except those who prefer to do it themselves of course.

 

This guy really understand the Helmholtz method, it is a COMPLETE system if used correctly. Bravo.. About 1 in 10,000 really get it.. 

The ROOM, and then the room and after that, the room and when it's all said and done, THE ROOM!

mahgister get's it..

The rest are settling for "good enough for me". That is just fine also. Some want more, some want less. That is what makes the world go round..

I'm 100% sure 80% of the audiophilers out there have spent a lot more on their systems than me.. I commend you.. The time I spent learning about room acoustics has been the single greatest enhancement of ALL the changes through the years of listening.. It was also the least expensive..

Thank you mahgister, MC, OHM, and a few other...

"The marketing of luxury goods has a common thread in that the high cost of the item is actually a feature of the product. Exclusivity is a selling point."

This, a million times over.

And, the fact that others know how much your stuff cost is very important.

 

Yes, there are plenty of people like this.

If it gives a sense of security and enhances their confidence and makes them feel better about themselves, then good luck to them.

I'm sure their custom is highly welcomed for keeping the wheels of commerce lubricated. 

Only, just as long as they don't insist that their stuff is in any way superior sonically.

There's absolutely no need to misguide and breed misplaced discontent amongst those with less financial means and or different priorities, is there?

@asctim The author, Robert Harley, knows this. I know that because I once read something written by him that was both original and actually made sense.  He is not being honest.

However he also knows that his target audience either don’t know, don’t want to know, or don’t care, seeking some/any justification (however ridiculous) from an appeal to authority such as himself writing for the esteemed TAS.. See also what @8th-note says, above.

I’m highly skeptical that there’s any important signal information that is being mangled by the $400 DAC ... that would ruin the potential of the $10k integrated.

The $400 dac very likely has a highly compromised output stage. So, a marginal dac with a compromised output stage...there is a chance that it might sound good but a whole lot of fortunate accidents would have to occur for that to be the case. What often occurs among the well heeled is that they pay extra for the dealer and/or manufacturer to remove variables that detract from the sound. If someone's income averages $1,000 per hour, its highly unlikely that person would willingly spend 20 hours to discover the best $400 dac. Multiply that if someone is on a quest to do the same exercise for amps/preamps/cables/speakers. So many scoff at the value a trusted dealer brings to the table...I happen to believe they save many people the frustration and random successes that can sometimes happen. Is it more or less expensive to get it right the first time?

The notion that the potential of a $10,000 integrated is wasted if fed with a $400 DAC suggests that the $10k integrated is doing something correctly that the $400 DAC is not doing as correctly, but perhaps a $10K DAC could do as correctly. It’s the notion that one component is more close to perfect while another is tarnishing the signal in a way that is uncorrectable by the better component. If this is so, we need to define what that "perfect" is. It would suggest some kind of pure, untainted quality of the signal is being lost by the cheaper DAC. What could that possibly be? It certainly isn’t frequency response, or phase information, or distortion or noise. I’m highly skeptical that there’s any important signal information that is being mangled by the $400 DAC (assuming it's not some peculiar design that intentionally deviates from linearity or adds distortion) that would ruin the potential of the $10k integrated. However, if the output of the DAC and the input of the receiver are not appropriately matched in terms of level and impedance requirements, then the potential of both of them could be wasted.

May I point out though that you seem to frequently imply that great gear might be a waste of time and money

You put your idea in my mouth...I NEVER say that ever.... 😊

i said that ONCE an audio relatively good system is chosen at any price and accordingly to your wallet, any upgrade WITHOUT and BEFORE optimization of the chosen audio system is a lost of money...

Is it clearer ?

And the improvement produced by acoustic optimization is so great, if your starting system of choice is well choosen to begin with for sure, that MOST subsequent upgrade will appear preposterous if you take in consideration the S.Q./price ratio...

I said "most", because if you start from a 50 bucks used speaker set like mine upgrading to a 100,000 dollars one, no room treatment and even no mechanical tuning will replace this upgrade and make it meaningless... It is only common sense...But dont laugh at my 50 bucks speakers, your smile risk to be colored yellow listening them in their room... 😁😊

 

May I posit that if your room is, in fact, exceptionally tuned that a great system dropped into your room would outperform an average system in the same room?

Sorry but you did not understood my point... 😁😊

First my room is relatively well optimized accordingly to my ability...Not exceptionnaly tuned...This will be a ridiculous pretense and boasting...But i am satisfied yes and very happy...It takes me months each day of tuning listening sessions...Nothing is perfect BUT....

Second acoustic tuning is not ONLY classic room passive treatment but more importantly mechanical control with two types of Helmholtz devices, resonator who diffuse et absorb selected bandwidth and diffusers who only diffuse selected bandwith...

Third, my room is mechanically tuned FOR A SPECIFIC SPEAKERS, and FOR MY SPECIFIC EARS if i drop inside my actual room a new speakers with a new dac and amplifier, all the tuning process must be redone from the beginning with listening experiments tuning adapted to the new speakers systems if i want to reach the peak working optimal level of the new system ...

Fourth, acoustic optimization can improve a low cost system OVER a costlier one ONLY if the costlier one is not itself optimized in his own adapted room and is in a nude room like most showroom or most living room ...

Then no acoustic magic trick can transform a low design quality in the highest one ever... Common sense is need... 😁😊

What is the best system that you’ve heard in your room?

Mine for sure for the reasons given above... 😊

In any room?

Homemade speakers from Tannoy 15 inches dual gold cones and big magnepans, my own past 12 inches Tannoy, Quad electrostatic speakers also , all these were better than my actual very good Mission Cyrus 781...

Then why i prefer my Mission Cyrus now to all of them...?

BECAUSE my room is optimized for the Miussion Cyrus, none of these others better speakers were in an acoustically treated room and certainly very far from a mechanically controlled room which is the only way to adapt the room to the speakers...

 

You get no argument from any seasoned audiogon participant.

The reason is simple: ONLY acoustic and psycho-acoustic can explain sound management and perception...Electronic devices are tool to convey some selected acoustical recorded information from one room perspective via a studio to my room/ears.... Audio is acoustical sound translation...Only gear marketing abusively call it pure reproduction...

 

 

 

Final word: real acousticians never boast about gear brand name guess why?

For the same reason mechanician can transform any ordinary motor to a super working one...The acoustician will make the best of whatever system is in the room...

There is always better motor and better gear for sure , but the important point is what will you make yourself of what you already have....

 

Thanks for your interesting questions...

And kind interest...

My best to you....

 

"The marketing of luxury goods has a common thread in that the high cost of the item is actually a feature of the product. Exclusivity is a selling point."

This, a million times over.

And, the fact that others know how much your stuff cost is very important.

@mahgister 

 

Respectfully, you make it abundantly clear in every thread on which you participate that acoustics and getting the room right are important. You get no argument from any seasoned audiogon participant.

 

May I point out though that you seem to frequently imply that great gear might be a waste of time and money. May I posit that if your room is, in fact, exceptionally tuned that a great system dropped into your room would outperform an average system in the same room? What is the best system that you've heard in your room? In any room?

The best systems I heard were indeed expensive but I found no consistent pattern of high price leading to better sound.

Now put these system in a room which is acoustically mechanically specifically controlled for each one of them, and the relation between good sound and price will be lost forever ....

Upgrade mania is inversely proportional to acoustic knowledge and to the law of acoustic optimization ...

Back to the original topic.....

When I read the article I had quite a laugh. We have to remember that TAS serves an industry based on the simple assumption that spending more money gets you better sound. Anyone, even multimillionaires, want to think they are receiving good value for their money so the theory of "accelerating returns" fits right into the agenda.

I'm sure this idea has been floating around high-end showrooms for some time and the magazine decided to give it an aura of credibility. This idea is right out of the salesman's handbook. When you've got a customer that is willing to spend $500K why would you tell him that he could get just as good of sound for $300K? In the real world, the salesman's job is to convince that customer that spending $750K instead of $500K will bring a huge improvement in sound. If the poor guy cheaps-out and only spends $500K he will surely be disappointed because he could have had a system that was so much better. for an extra $250K.

The other factor to remember is that sound quality in high-end audio is only one factor in the buying decision. The appearance and story behind the gear is a key part of the buying decision but one of the most important elements of the sale is the relationship the salesman creates with the customer. The personal attention that one gets when spending several hundred thousand dollars on luxury goods is an enjoyable part of the process.

The marketing of luxury goods has a common thread in that the high cost of the item is actually a feature of the product. Exclusivity is a selling point. The idea that there is a accelerating improvement in performance with increasing price is a wonderful piece of sales propaganda. A commission salesman's wet dream.

When VPI introduced its top end turntable the Japanese distributor complained that the price was too low. Their customers wanted to spend more money than that and it didn't matter that the VPI would compete with six figure turntables.

After going to two audio shows (pre covid) I came to the conclusion that the correlation between sound quality and cost is tenuous at best. The best systems I heard were indeed expensive but I found no consistent pattern of high price leading to better sound.

I don’t think Helmholtz was ever married.

"It is not the "ONLY" way to tune a room completely"

First Helmholtz resonators and Helmholtz diffusers like said rightfully @helmholtzsoul are the main and ONLY mechanical way to modify a room and tune it and also tune each speaker for each ear by the way ...

The greeks and Egyptians and Chinese and Helmlhotz the father of modern acoustic and of psycho-acoustic thought so...

«In Helmholtz resonators, we have acoustical artifacts that far antedate Helmholtz himself. Resonators in the form of large pots were used in ancient times by the Greeks and Romans in their open-air
theaters. Apparently they were used to provide some reverberation
in this nonreverberant outdoor setting. Some of the larger pots that
have survived to modern times have reverberation times of from 0.5
to 2 seconds. These would also absorb sound at the lower frequencies. Groupings of smaller pots supplied sound absorption at the higher frequencies.»
The Master Handbook of Acoustics Fourth Edition by F. Alton Everest P.216

Second, the fact that you use DSP confuse your mind...

«Is it not better to NOT push power into frequencies that the room gets excited about because its dimensions and positions of speakers and sweet spot? Of course it is.»

DSP modify the speaker response only , the H.R. and H. D. modify the speakers and room relation by modifying each of them at the same time for psycho-acoustic effect for EACH ear from EACH speaker.... DSP AND MIC. are not an integral part of the room like H.R. or H. D. are in their working way....They are used to modify the source information to your taste and adjust in ONE chosen way the speakers response to the room...They dont modify the room response at the same time for the speaker sorry...

My sweet spot is not IMPEDED at all by the mechanical tuning devices in the contrary, my sweet spot is created by them and not only by the precise location of my chair in a short one millimeter range but for a larger range ... Then i had a better sweetspot because he is effective in a larger dimension than one millimeter range and dont lost all his effective action after that ...

And try to adress the Schroeder frequency and bass limitations with DSP... Good luck....Room passive treatment +DSP will not do it....It takes a mechanical control of the room whose pressure zones modification are possible with Helmholtz mechanical devices to reach a better dynamic, and a better bass clarity in small room......

 

😁😊

---First, Helmholtz devices of any type are not mere  TOOLS...

You dont let tools scattered across a room after their use time... 😁😊

H.R. And H. D. are PART of the room, they modify definitively  the pressures zones distribution of the room by staying in place ...

A DSP tool and a microphone dont do that and after their job is done you remove them from the room...

 

--- Second , your warning about the modification of the sweet pot reveal you dont undertstand the way this grid work at all...The devices are there to mutually adapt the speakers and the room to one another...My sweetspot extended to a large part of the listener location than your mic/dsp method who has no value passed one millimeter or so....

I place some H.D. near the speaker bass driver or tweeter asymmetrically to help each ears to create the localization effect... I will not go into details ...

 

Is it not better to NOT push power into frequencies that the room gets excited about because its dimensions and positions of speakers and sweet spot? Of course it is.

 

The Helmholtz for example is a fix on something that is after that we have created the issue.

But it so a good treatment technology to have in the toolbox.

 

First this room "from Hell" is my laboratory, or dedicated room not a living room...
Then keep any sarcasm for yourself, people use them when they have no arguments and you seem articulate... 😁😊The photos in my virtual page has nothing to do with my actual room the images were taken before i iuse the Helmholtz method...


"Helmholtz treatment "only" work on ONE frequency and to bring down a peak in that very specific frequency and nothing more or less. Change the volume of the air cavity, or the length or diameter of the neck, and you change the frequency of resonance."

First Mechanical resonators are not DSP at all...Your comparison with DSP is flawed...
Why?

Because Helmholtz resonators (H.R.) absorb a larger bandwith and not a singular frequency...
And they DIFFUSE also other frequencies which are not absorbed...And they work in relation with the room geometry and size, and their placement is critical...Mine are mostly tubes with neck of various dimensions , some fabric cloth act as an absorbing material at the base of the tube end... They are made of different materials...

«Such a Helmholtz resonator has some very
interesting characteristics. For instance, sound is absorbed at the frequency of resonance and at nearby frequencies. The width of this absorption band depends on the friction of the system. A glass jug
offers little friction to the vibrating air and would have a very narrow
absorption band. Adding a bit of gauze across the mouth of the jug or
stuffing a wisp of cotton into the neck, the amplitude of vibration is
reduced and the width of the absorption band is increased.The sound impinging on a Helmholtz resonator that is not absorbed is reradiated. As the sound is reradiated from the resonator opening, it
tends to be radiated in a hemisphere. This means that unabsorbed
energy is diffused, and diffusion of sound is a very desirable thing in a
studio or listening room.»

Also all my H.R. are of different size, not one is the same in neck, lenght, volume or perimeter....For exemple one is 8 feet in my 8feet high1/2 inches in my studio, they ALL Differ by some ratio...
Then your comparison with DSP correction which use a one test frequency is flawed.,..A DSP dont absorb some bandwidth and dont diffuse some otrher bandwidth in some ratio at the same time...A DSP enhance some PRECISE test singular frequency...

Also i had a set of specialized Helmholtz diffusers or H.D. , which are way less known devices, this H.D. are OPEN TUBES OR PIPES, all of different lenghts and perimeter , then differering in volume, with a FILTERING GAZE or cloth fabric of different densities then of different absorptions properties... One mouth is open the other FILTERED by this gaze of various fabric densities or by a set a set of various thinner STRAWS of different size.... This created a powerful diffusion in critical placement....In particular near listening position and on the speaker themselves at precise location DIFFERENT for each one speaker by the way... Guess why? 😁😊

Location is KEY.... Like i said in my previous post i use the Haas law of the first wavefronts to tune my sound for EACH ear from EACH speaker.... My speaker are modified by H.D. placement around them or on them in an asymmetrical way to increase some acoustic crossfeed of large bandwidth...I even use a double two section foldable screen behind me to increase the acoustic crossfeed by the speaker A on the  phantom image of B and speaker A on the phantom  image of A for each one of my ears...

All the tuning was made on few months period daily, it was fun and very enlightening ...The work was exactly like a piano tuning but here it is a MUTUAL speakers/room tuning.... The H.D. and H.R. devices  circle the room from the "HEAD" speker to the "TAIL" speaker with the "BELLY" of this acoustical SERPENT being  my listening location chair with the  FOCUSING lenses of the   reflected waves  of this foldable screen behind my head...
Time and timing of reflected and direct waves are the KEY...Reverberation control is key...

«A sound field in a room is composed of direct sound and reverberation. The interaural correlation follows the sinc function corresponding to the subjective diffuseness
in a room, as the distance increases from the source, when the sound source radiates random noise. However, for speech signals a listener is able to localize the
sound source even in the reverberant space. Early reflections within around 30 (ms)
of the direct sound enhance the energy of the direct sound. This positive enhancement due to early reflections can be explained by the Haas effect or the precedence
effect [18][44][45][46] in terms of the binaural sound localization.» Acoustic Signals and hearing Mikio Tohyama P.202

 

 

All my 8 headphones are in a closet now... Why ?
Because my room/speakers give me an intimacy, a dynamic, a soundscape, an imaging SUPERIOR to each one of them... I cannot go back to headphones...

When you correct the room with electronical tool unlike my mechanical devices which are part of the room, you cannot tune the room for TWO Listening locations like mechanical room tuning, and the tuning location with a microphone feed back and test frequency are valuable ONLY for a "sweet spot" which measure around one millimeter you bend the head and all ,easures are amok... In my room the sweespot are larger in nearfield listening (three feet) or my regular position (8 feet).... The regular position is more like regular speaker listening, the nearfield is nore headphone like , BUT in the two positions, acording to the recording album, the soundscape CIRCLE me almost and the listener is not in front of the music sometimes, but in the center with instruments sometimes around me...it is relative to EACH RECORDING effect... I can hears the acoustic bubble specific to each recording choices by the studio engineer...

Then before moching the lack of esthtic of my room, and his alleged efficiency think TWICE....
"Just imagine to take 100 books and place them on the floor, and scattered around on the floor around the sweet spot, and a book is far smaller than a Helmholtz resonator.. i can not imagine that mess.."

 

Your description has nothing to do with my H. grid location RESONATORS AND DIFFUSERS size and precise working location function for psycho-acoustic effect and not only physical acoustic effect , these two devices are not the same thing also...

 

@helmholtzsoul I clerified the simplified short version. We are on the same page.

It is not the "ONLY" way to tune a room completely.

Is it not better to NOT push power into frequencies that the room gets excited about because its dimensions and positions of speakers and sweet spot? Of course it is.

 

The Helmholtz for example is a fix on something that is after that we have created the issue.

But it so a good treatment technology to have in the toolbox.

The bottom line is who care about money of components or synergy of the level of the same, if the room is untreated.

 

It is funny to see the focus on price, the results is audiophiles bringing whole their life gear in and out of the same poor room. And expecting a better results.. ..but they just get different results.

 Talking about "sideways" moves. 

Room tuning may be something an obsessive/compulsive listener could chase around until they're ready to gloat about it (I think rooms generally can add a sense of realism with only furnishings and regular stuff, unless maybe your room is an abandoned shipping container), or not. What anybody likes or doesn't like about the sound of a system is utterly due to personal taste, and in my experience that seems to vary wildly. My current system of relatively modest items chosen and kept or rejected and replaced, seems astonishingly better sounding than any I've heard anywhere at any price mostly because it's there by and for me. I hear some interesting improvements from cables or amps getting their legs after break-in, but that's simply fun and not a huge deal. Unless I need to gloat.

Helmholtz treatment "only" work on ONE frequency and to bring down a peak in that very specific frequency and nothing more or less.

 

NO! they can be used to notch around a frequency. To contour a particular frequency or by using slot vs tube vary a single resonator to encompass several frequencies with less control but over a much wider bandwidth. 

Helmholtz is the ONLY way to tune a room completely. 

I've even used passive radiators as frequency collectors vs frequency producers. 

The concept can be used to increase a given frequency by notching around it and lowering the over all SPL. I use several different resonators and  two huge 100+ cubic foot pipe collectors. It looks like a pipe organ turned sideways in both corners of the front wall, floor to ceiling 36 x 36 x 96" but they are behind the wall. Different diameter ABS tubes are sticking out of the wall.

Many of the tubes are capped, about 1/3 aren't, the ones that ARE capped are used to diffuse, the ones that are not, are used for tuning. You simply push or pull them further in or out of the wall. You pick the correct size 1/2" - 6" pipe uncap it and tune it. I also use 4 more adjustable tube traps for the rear and sides, with slot style wall resonators for fine tuning.

You can hear a fly fart if you want.. :-) I think that would be in the 18khz range.. LOL

10hz to 15khz 100% tunable..

BTW ALL the traps on the walls and floor are decoupled from the wall and floor..

Speakers, Subs, and any object with equipment on it.. (Especially TTs) are decoupled. A sound changing experience for life. The same for servo driver systems and small planars.. A different sound that is very appealing to me..

Equipment? Gear? Take your pick and go from there. After the ROOM everything else is pretty superficial. All those thing that did make such a big difference before don't amount to a hill of beans.. 10K integrated means squat then, when a 2K total system will sound better. It's the room and tuning it along with decoupling and refining the quality even more.

Did I mention electrical? :-) This is when "Doris get's her oats".

Yesterday I adjusted the crossover setting on my subwoofer and changed its position relative to the front wall. Let's say the crossover adjustment applied about 50 cents worth of time and effort to a $20K system.  The bass response  improvement may not have been as great as adding a subwoofer in the first place, but then, the cost was far far less. 

However, the "law" won't necessarily apply if you just start fiddling with dials (or spending money). You first need to identify where your system needs improvement (for example, in the sounds of kick drums.)  

 

"As for price, you are not going to get top quality sound from a $500 tt or a $700 dac. $7k for a dac, $10k for a tt/cart/tonearm, now you are getting into good sounding gear."

Pay more attention to the quality of engineering and design implementation. Most importantly listen with an open mind and let your ears be the judge instead of the price tag, unless bragging rights and status is all that really matters to you.
