I'm confused, Tim. In one sentence you say "pro recording" equipment, and in the next you talk of DACs and amplifiers, which is reproduction gear. Yes, it might be used mainly in the rooms of recording studios, but if it is of excellent quality then it should be just as competent in a home listening environment - it should easily show up "high end consumer audio". In that regard, it is interesting that some of those "professionals" who are supposedly aiming for the highest quality in their recordings spurn the "pro" gear, and use ambitious consumer components ...
The main failure of pro gear, IME, is that it does a poor job of recovering low level detail, for various reasons; the standard parameters may be fine in the measuring, but the level of distortion of "inner detail" is too great.
I agree Mike Fremer doesn't want to get it ... he posted a video supposedly showing the vinyl replay being superior to a digital playback - yes, they were obviously different, but a tiny bit of analysis of the waveform showed dramatically different EQ'ng for the two cuts; I mentioned this to him, but got no response.
