Audibility of "typical" Digital Filters in a Hi-Fi Playback

In real life my doctor's medical training and degree trumps my lay opinion without being called argument from authority. That authority has value Fantastic Amir, we agree! If we do on anything, I will have to go and hang myself.Let's start: "how do you even imagine that one can hear a difference between two systems, one with noise 98 dB down and the other 146dB down, when the level is set to peak at 96dB?" How do you explain how "obviously difference" fails to show up in even the worst kind of ABX test? I have yet to see a whit of evidence that "high-rez" matters for final presentation to a listener. Have you any, bearing in mind that citing non-blind-testing proves nothing but the incompetence, the complete and total incompetence, of the person citing it as evidence. Bear in mind the hard evidence for the persistance of loudness memory while you're at it. I have my doubts that SACD or DVDA are much, if any, of an improvement, but the test is just blisteringly hard to run, and more likely to respond to artifacts, either positively or negatively, than it is to actual differences. Time alignment, level alignment, frequency response in-band can all throw it positive, lack of training, bad test environment, bad time alignment, etc, can also cause false negatives. Subject verification, likewise, is an important issue. So, I remain undecided, but I note that I own a lot of CD's and not a single SACD or DVDA, except for some people have sent me. Amir, hopefully this meets your luminary-authority requirements sufficiently as not to question it? The "whit of evidence" and non-sighted test manifested itself in the form of Stuart's paper and us passing the forum ABX tests. JJ is on private industry thread where we are discussing these latest developments for some time now. He has not objected to anything we have been saying. Maybe he is dumbing things down for folks like you in forums. Go live what, buster! Now where is the youtube video for how to make a noose....
