Hi folks,
I have been following this thread for a few days and would like to make a couple of observations that I THINK have not been covered.
The superiority of the LP medium as concerns the expression of musicality is, to my ears, clearly superior to CD in ways that have been covered by other respondents to this thread. There is one aspect of the issue of "noise" that I don't think has been adequately covered, and I think explains why many find the LP's arguably higher noise floor unobjectionable. The "noise" of LP playback occurs outside the sonic plane of the music, which is why many can "listen through" the noise. This noise is a result of the mechanics of playback, and is not woven into the fabric of the music content. The noise that I hear in CD playback is, in fact, in the same "plane" as the music content, and consequently much harder to ignore.
Speculation as to the quality of Sufentanil's classical music pressings and turntable system aside, I propose that one of the reasons why he finds the noise on his classical LP's so objectionable is, ironically, the superiority of acoustic unprocessed music recorded in a real acoustic, as a test of a playback system's ability. I wonder if, in fact, there is that much more mechanical noise (pops, clicks) present when he plays back classical LP's as opposed to pop LP's. Mistracking is a somewhat seperate issue; as has been pointed out, tracking an orchestral brass section playing fortissimo is going to be much more taxing to a cartridge/arm than just about anything that I have come accross on a pop record. I suspect that part of his sensitivity to the mechanical noise is that it is heard in stark contrast to the purity of unprocessed music, while an occasional pop or even mild mistracking heard in the context of the distortions of electronic/amplified musical instruments, gross processing and multitracking, become pretty unobjectionable.
While my two comments may seem to contradict each other, I think that this may point to a listener's preference for a certain type of music over another. Speaking for myself, I have found that when listening to music that doesn't particularly rock my boat, I tend to be much less tolerant of the problems in it's playback. While music that really turns me on, I can enjoy on my shower cd/radio player.
Best to all.
