I agree that sound quality has a major influence on my enjoyment of a recording. If I have two recordings of the same piece, I’ll play the better recorded one far more often regardless of performance. This is especially true for recordings of pieces that are new to me. When I first heard Shostakovich’s 24 Preludes and Fugues at home, it was Jarrett’s recording. A bit later I listened to Scherbakov’s (on Naxos?). I’m not so knowledgeable as to be able to rate the two, but I enjoy the sound of Scherbakov’s much more and, consequently, it’s the one I play.
From this site and others, I have the impression that many musicians find the sound less important than the performance, but I just don’t listen the way they do.
