Funny how you call Hirsch, Aczel and Nousaine "extremists." I have never heard people who rely on proven scientific methods extremists, except by climate change denialists and evangelicals.
Do you think only manufacturers do ABX tests? Silly wabbit. Why, there are three names mentioned right above, none of them manufacturers. I'll add a couple more: Arny Krueger and David Rich. You may not have heard of them, because they actually work professionally in audio. But, whatever. Tell you what: Head over to Hydrogen Audio and join in on the listening tests forum. You really might learn something.
Apparently you once read an article about ABX testing, and now you're an expert. Doesn't work that way, sorry.
Your initially stating what a component costs retail and not saying what you actually had paid was misleading.
Since all DACs and transports sound the same to your ears, you could have purchased a cheap CD player instead of the PS Audio DAC. But you didn't make clear if you paid $750 or much less for it, so who knows. When your unnamed transport or PS Audio DAC dies you won't have to spend more than about $150 for an all-in-one CD player that sounds just as good to you.
This may come as a shock, but component manufacturers that arrange private blind testing do so precisely because the tests do
indicate audible differences. They would not bother investing the time and expense of such testing if the results always showed no differences. The engineers want to know what sonic parameters are most obvious to participants and what deficiencies must be improved. Sometimes the blind testing helps. Those tested typically include company staff, invitees, and the engineers themselves. You should attend at least one or two because, in your language, "You really might learn something."
I wish the recently late Charles Hansen, founder of Ayre Acoustics, was still here on AVS to explain his firm's use of blind testing. Feel free to do a search of his posts on the subject. "You really might learn something."
Instead of understanding their hearing limitations, Hirsch and, most particularly, Aczel and Nousaine futilely tried to push an ideology based on their own pseudoscience. It failed and all that remains are a few folks who still cling to various versions of "All [fill in the blank] sound the same."
On the other hand, since all iterations of blind testing are of such great interest to hobbyists worldwide and the tests provide such a wealth of valuable information, you should subscribe to the highly popular magazine devoted to the subject at www.itdoesnotexist.com
You want real science? Visit with audio engineering teams and inquire about their research projects and the audio components they are spending countless hours developing. Also, ask if you could participate in their next blind tests. "You really might learn something."
