I've felt for some time that there's a disconnect between quality judged on measurements and quality judged by audibility. Just about any product, including the Amazon Basics amp given a broken panther recently, are likely to be audibly transparent in general use.
Even if the specification isn't met fully, as long as it's Good Enough, shouldn't that be reflected in the rating? If ASR is the one site that can be relied on for purchasing decisions, free of commercial pressure/sponsorship and audiophile nonsense, then I would expect the relationship between test results and suitability for the job required of the item to be reflected in the rating, and not just SINAD.
