I read the thread and most of the comments seem reasonable to me? There are a few trolls but it's hardly a SBAF bash thread or anything.
The fact of the matter is that judging AVRs/AVPs based on SINAD can be silly since many perform "well enough". And it's also a fact that Amir's ratings/comments have significantly changed over time. Early on, he was basically calling every single AVR broken because they didn't perform as well as desktop DACs. Now, as stated directly
in the recent Anthem review, he "grades on a curve", with
$15K AVPs that barely equal a $1200 Denon still passing the test
This has, IMO, unfairly left some older reviews judged as "broken" when they are fine, like the Monoprice HTP-1. The problem that gave it a headless panther was later confirmed to be fixable with a setting, and, honestly, not something that would ever be triggered by regular content watching. But it kept the headless panther despite general performance that is very similar to the previously mentioned $15K Storm Audio AVP.
I am not bashing ASR, however
As multiple comments state, Amir's testing IS valuable and does confirm whether or not the basic electronics are broken, IF you know how to read the reviews. For example, it uncovered the fact that
Marantz units use a very slow filter which will pull down high frequencies in the audible range. And
Amir himself has stated that ASR isn't intended to be the best resource for functionality/features, so it is reasonable to look elsewhere for information about that. Which is very important information -- functionality/features are the entire reason you buy an AVR instead of a basic multi-channel DAC.
So, yes, it's totally correct to say the reviews are a good source of information for AVRs but you should not base your purchase solely on them.
