just because you CAN; something that has no impact on SQ.
Obviously you measure what you can. You are correct that poor objective performance does not preclude good subjective acceptance. But, I think it far more likely we are all tolerant of, or even prefer poor performance rather than the existence of an unidentified element that causes good sound.

If you find that tests of noise and THD using uncorrelated sine waves provide complete insight to what you hear, his tests are meaningful.
OTOH, he did find a minor flaw in the LPS-1 power supply I use which was later rectified. :)
I do find it more useful than the Vogon-poetry listening impressions we usually get.

I learned it was an utterly useless metric when I was a teenager. Information that conveys no knowledge.
I learn far more from those who understand music and its subtleties. To each his own.
But I don't like to see a lot of high order harmonics, or worse, an-harmonic peaks. I don't see why THD+N should be above -80 dB or so. Also, I don't like to see a lot of mains noise, shows bad design and workmanship IMO.
And, yes, speakers have a lot more distortion, but I don't see that as a reason to accept a lot of noise and distortion from our electronics. I think some people just want to justify a pure oenophile-like approach to audio where there sense impressions won't be contradicted by some propeller-beanie with a voltmeter.

On what basis?
A pure numbers man would note that the noise floor of a typical listening room is far above the level of noise, distortion, and other artifacts produced by any digital source with a reconstruction filter, even the poorest measuring ones. By the numbers, the only digital sources that should have audible problems are filterless NOS, which are intentionally designed to pollute the audio band with images and noise.
Despite that, most of us perceive differences in sound quality from different digital sources. Some audiophiles insist they are huge. Personally, I find them small, but often meaningful. I've never found an objective metric that could help me pick a digital source.
Speakers are at the other end of the spectrum. I find a very strong correlation between what I see in a full suite of measurements and what I hear. If Amir wants to contribute to audio science, he should start there. But he seems to prefer measuring DACs, perhaps because they are the easiest things to measure.
so, for a long time, audio designers did -- many (not all!) of them succeeded in producing marginally stable, bad sounding amplifiers that measured great (at least with respect to THD and also, sometimes,in terms of bandwidth).
You know what HH Scott's Daniel von Recklinghausen said, I reckon. :)
If not, see link below.

...and we all know what happens to those poor souls that suck up to Vogon poets.
Totally incorrect. There was no such flaw. Perhaps you missed Uptone's rebuttal?The product update to Mach 2 had absolutely zero to do with ASR.

Perhaps you're referring to something different than I. The original Meanwell energizer was exhibiting "high-impedance leakage" and a wire running from AC to DC output ground was installed. All subsequent models contained that enhancement.
I just purchased the updated version directly from them.
Post #59
Notice the dates involved. The audioscience post was in August.
In September, John Swenson (the designer) acknowledged the observation in September with this post
The fact is Amir @ ASR had no clue what he was measuring and made several confirmed incorrect amateurish technical observations.
Out of sheer envy and mean spirited intent he starts out with an agenda which is to tear down successful companies like Schiit and Sonore because he is a failed engineer, failed business man, and a total loser.

..actually he does...he was an "admin" at the horrific WBF site, and he made it clear that was his agenda.
in fact, he fully admitted to not owning a SINGLE piece of music when he started ASR. None.
He had a serious complex after being exposed as a failed "technology" executive at Microsoft when the many of the internal emails were leaking from the DOJ anti trust suit. It showed Bill Gates strongly reprimanding him and his team for allowing Apple to take them by surprise with iTunes and the iPod. He then started an audio related business which failed miserably.
I'll bet he or she is a bitter, wounded SOB.

The place is vile. He was ousted after an uprising..that may tell you thing, he was even too insufferable for this place.
ha ha ha ha ha ha ha!
Some farkin' Einstein he, then!
Why not blame the underling!
jm
The thing is, it actually worked for him. I don't think Bill is especially concerned about having enough money to retire on.
Amir has suffered one humiliation after another. He was forced out of Microsoft after he backed HD-DVD or Blu Ray..(LOL!!!), failed to come up with a download store (with 5 years and unlimited billions allocated)....
The Zune, Windows Media Player..all laughable failures in the scrap heap.
Sounds like you've been doing oppo research on the guy. Wait'll they find out about his emails!
I have no idea what any of that has to do with measuring electronics with an Audio Precision analyzer, but that does seem to freak people out in unusual ways.
Ok, let me spell it out.Anyone can measure with the best equipment on the planet. Knowing how to interpret the results and what conclusions to draw, ALL this assuming you have your testing set up correctly, is a different matter.
Amir has zero credibility, zero engineering chops and is intellectually dishonest and disingenuous. Is that clear?
Here is an example He "measured" the Sonore microRendu streamer, claiming it caused a "6 dB rise" in the output of the DAC. No it did not. He was using the WMA which was not outputting bit perfect data. He made several other bufoonish mistakes in that debacle. He has to suffer the public humiliation of admitting his mistake after denying it vehemently.
Another example is he measured "noise" in one product that turned out to be a ground loop in his own setting.
He should be shut down.

I disagree with your assertions and character attacks. There are a lot of experienced engineers, scientists and audio technicians on ASR and Amirm's work is essentially peer reviewed in real time on the site. That is the scientific method in action.
DK.RoK
Ah, one of the faithful appears to defend the honor.
Sorry, but someone who starts a site called AUDIO Science Review and does not listen to or know the first thing about music defines the term absurd.
Ah, more ad hominem attacks, I'm one of the faithful and he doesn't listen to music. I raised the topic of scientific method and peer review which you ignored. I have to leave this discussion now, I'm out of troll biscuits.
DK.RoK
....nice try with trying to float the notion of "real time" peer review
That was a good one.
His history at Microsoft has nothing to do with anything. This is the attitude that anything you can dig up about the "other team" is grist for the mill, and it indicates a level of investment in destroying the "opposition" by just slinging whatever schiit you think will stick that is very telling.
And yet, he used his Microsoft gig as the vita for his supposed expertise in measuring and passing judgement on equipment.
IMO, he came across as a bitter guy with an agenda. What was scarier, however, were his 'followers,' who hung on his every word.
Hey Daverz, looks like you were here back in the days when I was active here and moderating the tubes forums. After being away from audio forums for 15 years, I got back into audio forum participation when I discovered ASR.
Looking with my old "AA moderator's eyes" the antagonist here registered two days ago and started ranting and raving and attacking AmirM and ASR with a couple of cherry-picked negatived from a large body of excellent science and testing. Looks like someone in a fit of rage because some product he likes tested poorly.
OTOH, I see a number of longer-registered AudioAsylum inmates posting reasonable responses only to get smacked down with angry babbling. Apparently a lot of the "old-timer" good-guys are still hanging out here.
I enjoy ASR these days because of my many years working in science - and a lifelong hobby of audio. Amir's stated agenda - which is supported by his actions - is for audio honesty and truth. In some ways, he has facilitated a new competition to see who (from around the world, big and small) can make the best performing audio electronics, although a lot of the focus is on headphones and IEMs, which I am not into.
(While hanging out here tonight, I noticed that one of the discrete AA ads was for Rich Brkich's Signature Sound . I bought a David Belles tube preamp from Rich many years ago, and more recently, a used 1993 Classé Model Seventy power amp in excellent condition. I had the amp shipped to Miami from New York, and then forwarded to me here in the mountains of Western Panama, where I have lived as a retired expat since 2012. Even though Rich is an upstate New York dealer, he was excellent to deal with both from California and from Panama. (He is also an engineer, and thoroughly tested the amp, and then ran it driving his office system for a week before shipping it to me.)
"...back in the days when I was active here and moderating the tubes forums. After being away from audio forums for 15 years, I got back into audio forum participation when I discovered ASR." Dave VH
Are you looking for a moderating job at ASR and proving your loyalty and unquestioning dedication to Amir by offering up your fanboi defenses? You actually went to him and bragged about your posts here? "Look at me, Amir, I'm a good boy! I will be loyal, dedicated and unquestioning in defending you." LOL.
We know Thomas left ASR for a brief period after discovering his boss is less than honest. He went over to Computer Audiophile/Audiophile Style looking for a new home, but after realizing they weren't interested in his moderating duties, he went crawling back to Amir, promising renewed unquestioning loyalty and dedication.
Here's an example of the character of Amir. On his site there are a few Trump supporting Christian nationalists who would like nothing more than to see Amir's people and home country eliminated. Travel bans, sanctions, wars, etc. These are people Amir would consider his ASR friends and he's perfectly aware of their views. Does Amir care about their views and support on such matters? Of course not. As long as you give him support on his site and give money he's perfectly okay with it. A total sell out and proven liar. His ancestors should be proud.This site linked might consider removing Amir's name (#28) if they're purpose is to promote positive perception of their country and people.

My, my, my. More whining and lashing out desperately with unfounded personal insults by an anonymous AudioAsylum inmate who registered yesterday - October 20. (I carefully checked the date this time.)
Those who know me - in person and online - know that I am honest and forthright, and dislike bullschiit. Although ASR is owned and run by Amirm, it hosts an incredible collection of intelligent, educated and rational participants from around the globe. Although ASR is a relatively young internet audio forum, is already very popular and web traffic - the number of visits to the site - is increasing as its popularity grows steadily. Many people like the atmosphere of honesty and the encouragement of transparency in business and advertising shared by the owner and the regular participants at ASR.
Those of us who participate regularly there appreciate all of the hard work Amir does to test audio gear, and the way he not only praises those who offer products with excellent design and engineering, and criticizes those who don't - and won't. People who come to ASR to defend poorly designed and manufactured audio gear are met first with reason, and later criticism and ridicule if they persist in defending shoddy design, workmanship and lousy performance. We (the regular participants at ASR) feel good when companies like Schiit acknowledge issues and address them. Schiit products that are well made and perform as they should are lauded. Amir demonstrates that he certainly does not want to "destroy" any company, but would rather "hold their feet to the fire" and encourage them to improve their engineering efforts and perhaps become even more successful.
I have absolutely no interest in moderating any internet forum, and as a voluntary participant at that forum, I am a peer to Amir and the many science-minded and audio technology professionals who visit ASR. Even though some of the visitors there are internationally-known and respected pro- and home-audio professionals, we all participate in discussions as equals, and give respect to those persons have demonstrated technical expertise and shared it with us.
When you say "You actually went to him and bragged about your posts here? "Look at me, Amir, I'm a good boy! I will be loyal, dedicated and unquestioning in defending you." you are displaying a great deal of ignorance about human nature and interactions. Just like here at the Asylum, regular participants bond as a community of people with common interests. Many of the ASR regulars are knowledgeable about psychology and human nature, and find the frantic antics of the "Amir-haters" to be amusing and worthy of ridicule.
I have nothing against AudioAsylum.com. I enjoyed my years here and hope that the Asylum's unique collection of participants including many DIY'ers and "subjectivist" audiophiles will continue to serve that audience. Like most regular participants at ASR, I feel that if people want to fool themselves with sighted texts only, and wax eloquently using their unique collection of flowery subjective terms - go for it. However, false claims or the promotion of unverifiable performance characteristics, will lead to becoming a subject of ridicule if you cannot support your claims with hard evidence.
I absolutely enjoyed my years with SET amps, horn speakers and other esoteric audio components that would likely measure quite poorly - but I never claimed that those systems were "accurate" or "transparent." And I still might get another single-ended amp from a Chinese company - Meixing Mingda - that is endorsed by Polish tube guru Lukasz Fikus Lampizator. Don't feel embarrassed if audio gear you like doesn't measure well - just go for what you like and be honest about it. That attitude is a core value at ASR.
Bottom line - if Amir and the participants at ASR criticize products from one of your favorite audio companies, you should, rather then engaging in destructive campaigns of personal attacks, encourage those companies or persons to address the technical issues raised by rigorous and accurate testing and measurements. Yes, there may be debate about some testing methods or results, but you can expect differences to be settled by further testing of communication with other certified experts. That's the nice thing about science - it is self-correcting.
Like some other companies who have done so recently, your favored companies might to be able to improve their reputation, and likely gain new customers. And that is what the ASR'ers really like to see.
My goodness. A 2000 word lecture. Thanks professor.Where you can't defend is engaging in product evaluation via test equipment with an agenda, wearing a white hat as a self crowned consumer advocate, where you have no qualifications what so ever to do so.
You may or may not know that for years Amir tore down and panned gear via web photos with out ever hearing, touching, seeing that equipment. That stakes a staggering amount of arrogance. He was constantly trying to show he was smarter than everybody else.
Couple that with a serious narcissistic streak (as well as pathological liar), and the propensity to revise history, shows why no company with any common sense would have him within 1000 miles of their stuff.

I am a retired buy with lots of time to counter b.s. and personal attacks - how it that bad? And it's not a lecture - it's part of a discussion - are their particular points I made that you disagree with?
It should be obvious to anyone with the ability to read and comprehend, and a desire seek truth, that Amir's "agenda" is to expose shoddy design and engineering, and he clearly - and quite often - states that he encourages companies and engineers to do their work to higher standards so everyone can benefit. And he has demonstrated his "qualification" to do such evaluations many times, and has an excellent technical background to support his efforts.
That Amir has negative and destructive agenda is a figment of your imagination, apparently after one of your favorite oxen was gored. You have no evidence to back it up.
Many aspects of industrial design and engineering can indeed be evaluated and criticized from photographs. How can you not comprehend that?
Just out of curiosity, what are your qualifications with regards to psychology, audio hardware engineering and manufacturing methods?
Why get so upset about a guy who likes women wearing lamp shade hats? :)
"2 days ago"
Are you being disingenuous or just not reading correctly? Registration was 2 weeks before this thread. False narratives seem to be an ASR trademark.
OMG - my glasses are quote old, and I misread October 7 as October 17. The horror of it all!
And please, kind sir, explain how that 10 day discrepancy on a 7,200 day-old forum is significant!
But then again, you have provided another opportunity to demonstrate that ASR and it's regular visitors admit and correct their mistakes.
...the way your post read is that I registered here just to join the ASR thread...which clearly is not true.
For the record, I don't believe this was intentional, but needed to be corrected.
You can pretend that his past incompetency has no bearing. Your prerogative.
His agenda, deep rooted bias, and technical blunders, however, cannot be ignored.
Your post reminds me of this Global Warming cartoon...
False equivalency.
The ASR charlatan came to false conclusions and made rank amateur mistakes
in procedure. There is no science there. Just an agenda.
LOL! An dedicated technical expert makes a couple of errors among hundreds of procedures and corrects them when they are discovered and pointed out to him. How is that bad? Isn't that the way science works? Like all good science-minded people, Amir accepts corrections, and continues to make serious efforts to do science properly - unlike the people who pass off lousy signal-to-noise and high distortion as high-fidelity at outrageous prices.
Even Schitt bought a new audio analyzer after being called out for poor engineering by Amir - and they have since improved the performance of their cool and trendy offerings. What, in your opinion - is wrong with striving for low distortion and a high signal to noise ratio?
OTOH, PS Audio has been defensive, and are trying to justify their poor performance with respect to true high-fidelity electronics. But give them credit for publishing some of their lousy specs - hidden somewhere in the advertising copy.
Audio electronics used as fixed (non-variable) upstream tone controls or signal modifiers seems rather silly to me. Doesn't it make more sense to keep the character of recorded music flat and accurate as possible from source all the way to the speakers and then do whatever you want to the signal with DSP? Does it really make sense to randomly adjust the audio signal via sound-altering electronic components and cables.
And don't get me started on listening sessions where people can only hear differences if the know in advance or during the session what they are listening to. Ever hear of psychoacoustics - another branch of science? Are you aware of the proven fallibility of acoustic memory for moderate differences, much less small and subtle differences?
I am aware of the technical "flaws" in some of the gear I've owned over the years, but still thoroughly enjoyed it. In 2003 I owned a 2A3 Italian-made SET that was hand-built by Attillio Caccamo of Tektron. It was fed by a custom 6sn7 transformer-coupled preamp from Australian Mick Maloney, and the speakers back when I had a nice big living room were Klipsch Forte II's. Most of the components probably would have measured poorly, but I did not care.
Like most of the regulars at ASR, I believe that people can - and should - listen to whatever sound system and music they enjoy. But I just don't like "charlatans" who pass off amateur-level design and implementation as SOTA. Seeking truth while acknowledging errors when they do occur is perhaps why ASR is more than twice as popular as AudioAsylum in terms of WEB traffic.
Ok, I can see what is going on here. It is clear you have a passive aggressive attitude towards successful audio companies and their "trendy" offerings. I can see this is exactly the ASR target audience.It is also clear that the vast majority of ASR disciples have no zero listening skills and need a false charlatan prophet to tell them what they are hearing.
Quite telling that no company will send this tone deaf clown any gear, and he has to buy it outright, or beg or borrow.

Quote: Quite telling that no company will send this tone deaf clown any gear, and he has to buy it outright, or beg or borrow.
Actually, companies that make well engineered components do indeed send units to Amir for testing. Apparently you don't know much about the website that you are disparaging. Many people drop ship new and ship old components to Amir for testing, willing to delay receiving or using those electronics for a couple of months just because of Amir's stellar reputation for honesty and accuracy.
Amir welcomes challenges, and if proven wrong, will admit it - but significant errors are infrequent - the forum itself is the peer-review platform - that's a good thing - wouldn't you agree?
Have you even noticed that companies whose products test poorly often attack the method but don't deny the data? Or they declare the bad results irrelevant and insist that the lousy engineering, designs and sub-par performance is not important.
Audioasylum ranks #240,000 in the world according to Alexa. WBF has sunk to #400,000. AudioScienceReview is at #104,000 - much more popular than both.
Clearly, there can be no rational discussion with members of a cult.
Amir is a dishonest, incompetent, and pseudo engineer with hate in his heart.
I'm sorry that you are unable to continue and respond to my honest and forthright comments and questions.
Anger and unjustified personal attacks can wear a person down. Perhaps another time - after you've actually become familiar with ASR and its rational, science-based approach to audio.
Nice circle jerk you have going on in that thread at ASR.
One brain dead ASR Zombie even posted about your dear leader:
"He's got fantastic values , has been courageous and unbelievably generous in his life. His story from start to now is inspirational and his true success in family and life is way beyond what most could even imagine."
LOL! I laughed so hard I got a belly ache.
Fascinating to watch angry losers flail about. Male egos are incredibly resistant to rationality and truth when they have been bruised.
Ego? Nice use of psycho babble.
I appreciate all the quotes at ASR.
I am on my way to being famous.
Now go ahead back to your circle jerk.
I think the applicable term is "infamous," not "famous." As in being infamous for opposing openness, honesty, rational thinking, and productive discussion.
Also, most people understand the meaning of the word "ego" and to refer to that as psychobabble, and then close with yet another childish insult is further evidence of irrelevance in the real world.
You want to get into the psychobabble?
Here is distinct proof that ASR not only not rational, but dishonest to the core.
The thread starter already knows, magically, that it won't "measure well" and that is is a scam product. And of course the scum slurping sharks circle the waters.
Then Amir, who Uptone won't even sell a product at FULL PRICE, a stance numerous companies have teken....encourages someone to buy it then return it within 30 days. This is border line fraud.
Then the whole thing spirals into a lynch mob...FOR A PRODUCT THEY HAVE NEVER SEEN, TOUCHED, OR HEARD....
Pre determined narrative...as usual. Despicable.
You talk about science? Let's see some of it from you instead of personal insults and senseless blather.
