    I love the quote which basically says "I couldn't reproduce the manufacturers cheating claims without cheating so I cheated for them".

    The degree of bias is utterly contemptible. JA's claim to any sort of journalistic objectivity or integrity has been demolished.

    I might be confused here, but WTF is the point of independent measurements/review if the aim is to "replicate the manufacturer's own measurements."

    Perhaps JA now thinks that J Gordon Holt's comments about lack of honesty were an instruction rather than a criticism of the modern world of hifi. (Interview link)

    Damn. I used to buy Stereophile :(

    Science is all about reproducibility. If a scientist can't reproduce an experiment, the results are suspect. In this case, if the manufacturer's measurements cannot be reproduced, they are suspect. Reproducing the manufacture's measurements to understand the product sounds like a very logical first step. After that, running the product through a standard battery of tests produces results that are easy to compare to other products.

    This thread is a good summary of why after 40 years of buying/subscribing to Stereophile I let my subscription expire. Thinking back, my issues with Stereophile were part of the reason I joined up with the pirates at Changstar. How long has it been now?

    5 or 6 years. I never remember whether CS started in 2011 or 2012

    I can't remember what I had for dinner the next day. :p Sometimes. Anybody have the correct year all this craziness started? My apologies for the derail. Carry on. Hope we can get some realistic measurements on the DAVE at some point.

    CS started on November 2011. Most people were not aware of it. Something happened on May 12, 2012 which caused a surge.

    Maybe you didn't get to page 7, where GUTB blurts out that he's never actually heard a Schiit multibit product:

    https://www.computeraudiophile.com/forums/topic/31284-just-got-a-yggdrasil/?page=7 (scroll down)

    Later on the same page, he admits his working knowledge of the Yggdrasil comes from an unnamed review, presumably negative.

    Your choice to either admire the honesty, or be dumbfounded by the stupidity.

    I see what you mean, but does it apply here? Aren't What the company claims and measurements achieved by others, potentially two entirely different things? Why would it even be necessary to know what measurements the company claimed. By analogy, isn't this like saying that something had to be done to make a product sound like the company said it did?

    The less said about GUTB the better.

    And, unlike some here, I have only encountered him on a mere two forums. It was more than enough. I doubt my brain could survive the combination of GUTB and Computer Audiophile.

    It is important to reproduce claimed measurements: It tell one if the company meets it's own stated requirements (many times they don't - i.e. CHORD DAVE). It can also give some insight as to the intended application conditions and maybe even architecture. So on, and so on.

    If these measurements are not standard, it is also important to run the unit under test under standard measurements: It tells one how the equipment fair against it's peers.

    Thanks, @ultrabike
    Or... not. I suppose, if the attempt does not succeed. Or to point in what circumstances they could be achieved.

    Maybe I'm beginning to get it.

    LOL! It depends IMO.

    Consider in general that some random vendor claims their product can do this non-standard but awesome-sauce thing, and provides measurement results to prove this. Say it's jitter, latency, distortion with certain input or whatever.

    Say the description and measurement results fits in exactly with what one wants. If one is a developer, before committing resources to develop shit around this deal, one verifies that the product performs as the vendor claims.

    Many times I've found things are not even close. This includes algorithms, papers, products, you name it.

    There is a ton of bull shit out there. And a ton of good shit as well.

    Replication of measurements is key in these cases.

    On the other hand, if this is for an end costumer and we only care about the standard measurements to determine if something is not shit relative to it's peers, one may dispense with the non-standard measurements. Note some folks may still want to see that what the vendor claims is true, standard or non-standard, to establish credibility.

    In the particular case for CHORD DAVE, I don't think the measurements they performed where that non-standard or weird. They were actually close to what Stereophile usually does. Surprisingly so, as other more standard IMD tests exist, For example, I don't think Stereophile does 1 kHz THD spectrum for DACs showing harmonics all the way up to 20 kHz (-3 dBFS or even -90 dBFS).

    What JA said was that he did the best he could to make CHORD look sort of good, because at more standard levels, the tests they claim were way off from what he got. In other words, CHORD did horrible and their (CHORD) measurements are pretty much bull shit (unless JA got a "broken" unit).

    The criticism on JA has more to do with the perception that he should have been a little more vocal about the fact that CHORDs measurements were far off from the truth. And that CHORD noise and distortion levels were relatively high in the mids to treble region. Specially considering the price tag CHORD DAVE carries.

    Further criticism on JA is that he does not seem to be very consistent when reviewing products. Some products seem to be given a mild reception, even when they perform better in some regards than some highly acclaimed products.

    A reviewer is only human. And what the reviewer may like, others may not. But on measurements, I think one should strive to be consistent.

    Yup. Atkinson slipped in that -90db 16-bit measurement in without mentioning that he increased the gain on the DAVE to unrealistic levels that would cause clipping. Sometimes not mentioning something is just as bad as lying. Atkinson of course offered the lame excuse that he wanted to concentrate on the 16-bit -90db pattern; while conveniently dismissing @ultrabike's very crucial point that he's effectively misleading readers as to the effective number of bits of the DAVE (when the DAVE volume is set to a typical usable level). Atkinson just seems to be making excuses as he pleases and being inconsistent with his criteria.

    I get the feeling that Atkinson has been doing this so long, unquestioned, and really without peer, that he thinks he can get away with it today in 2017 when there is the Internet with a lot of smart people who can do and understand the same things he does.

    I have reluctantly come to the same conclusion Marv. I read some reviews from 15 years ago, they are different. More consistent. But gradually the reviews for what I thought was only decent gear was more and more positive in JA's reviews and measurements. Musical Fidelity comes to mind, no slam on them, but the more ad space they bought the more Musical Fidelity equipment got reviewed. And it got to the point that every new product from them got positive reviews. A certain amp I bought comes to mind. My experience with it was quite different than the description in the Stereophile review. I am not talking personal preference here. But the amp I bought had a very different sound than described in the reviews. It really was a poor design, no matter what your personal preference might be. My faith in the accuracy of their reviews began to gradually slip. This Yggdrasil thing is a perfect example. I guess when one is fighting for the survival of your magazine, your standards start to slip.

    Yggdarsil is amazing!

    If you enjoy music, just get it. Is it technically correct? Who cares. It is musical? it sounds like LIVE music. Even at low volume, the music comes through. Seriously have you heard the Yggdrasil yet? It must be warmed up, so the resistors in that R2R DAC are operating at spec, but once done, it is the fecking Schitt. Utterly amazing sounding.

    The same subjectivist argument can be made for the dave, or any other piece of equipment. If you like how it sounds, nothing else matters. I don't think anyone here would argue with that.

    This discussion is about the accuracy, and reproducibility, of the measurements taken by stereophile magazine. There is correlation between measurements and quality of sound reproduction, so to some extent, measurements matter. Also, stereophile proports to offer independent and trusted measurements, so the validity of said results is relevant.

    I don't think it uses an R2R ladder. You're waiting for discrete DAC components to hit INL spec.

    (Also not the point, this thread is discussing dishonest use of measurements right now, rather than subjective enthusiasm.)

    What's the difference between a non-sigma-delta multibit DAC (how Schiit describes it) and an R2R ladder? I though the Yggdrasil was an R2R as well.
