This is a general response to the initial question, which was an excellent one. ASR provides objective information that I can use to narrow the field of options when shopping; that appeals to my decision-making process. It won't to everyone. There are simply too many options out there promoted by those in the industry, and those whose pocketbooks permit ego-driven extravagances, and become defensive about justifying them. And if you're satisfied, good for you. But I'm just as skeptical of the "If it sounds good to you" school of thought as I am of religious devotion to data. The fact is, there are better ears than mine, and far worse. I can learn from both those better ears, usually musicians, as well as Amir.
Here's a parallel circumstance currently in the news. It occurs to me that the owner and passengers of the ill-fated submersible would be alive today if they had demanded objective evidence of the vessel's safety, rather than relying on the owner's sales pitch. Fortunately, no one's life is at risk making audiophile decisions.
