@mapman - I didn’t say "never", I said "usually". So, that is not the case. My system, in my acoustically treated room, with meticulous setup, is most assuredly resolving enough to notice the level of sound quality of every album I play. I even am able to grade the sound quality of each album with letters A, B, C, and D. Fortunately, almost all my albums are in classes A and B.
Hope this clears things up.
PS- two of my friends are recording engineers. They both have told me my system sounds as good or better than what they hear at work.
