Here's an informed opinion on ASR and the veracity of the measurements to be found there.

Take a moment and watch this Currawong (Amos Barnett) video from 34:55 to around 36:00

I know next to nothing about about ASR and Amir.

Are there any more details about (or reference to) his appearance at an Audio Precision presentation requesting a unit that is easier to operate?

If I was still involved with hardware development, I would also request easier to use test equipment. Pretty sure anyone would do so in any field with any equipment. The context of his question matters, otherwise ad hominem (i.e. the foundation of politics :tongue:).

This is partly why I ask. Amos does not go into detail except for saying that Amir is incompetent and mentions different measurement results from others, using a heat gun to heat components and an incident at an Audio Precision presentation as the reasons.

Is there a well written and evidence based critique of the measurements posted by ASR? If so, please link to it. I am not interested in a discussion about the correlation of measurements and perception, but rather the validity of his measurement methodology and the repeatability of its results.

I was made aware ASR earlier this year, but have yet to consume any of the content. If it can be shown that his measurements are fraught with error I will know not to waste my time.

Personally I have no axe to grind with Amir at all, and in fact came to his defence when he appeared (briefly) on this very forum some time ago.

I started reading ASR about 2 years ago and liked (and still do, in theory) the science-based position Amir espouses.
That said, there are numerous instances where his measurements have contradicted some very experienced and respected posters' findings.

Here is just one: https://www.superbestaudiofriends.org/index.php?threads/measurements-are-hard.5159/

There are others, but I'm not going to do all the work for you lazy buggers!  :dop:

The problem I have with Amir's testing is that erroneous conclusions can lead to inexperienced folk making poor decisions.
Many don't have the time, inclination or technical knowledge to refute his findings, and might take them at face value and as fact.

How many potential buyers have given Audio-gd amps a wide berth WITHOUT LISTENING TO ONE following his test results, for example?

I don't know Amir from a bar of soap, and still read the reviews on ASR from time to time (for the sake of completeness of course). But one line from Currawong's video sums up my feelings about ASR (and hardcore objectivists in general): Tone sweeps are NOT music.

Enough said.

Tone sweeps are NOT music.

sure .... but music is a collection of mutiple tones and frequencies .... so tone/frequency sweeps and analyzing various individual tones/frequencies are a relevant way of testing equipment for the purpose of music playback .... the problem is that many people do not know how to interpret the results of this analysis properly  :nfi:
