OK - I am not an audiophile snob by any means, but I do own an "entry" level high-end system consisting of Rotel electronics, B&W speakers (DM 602 S2) bi-wired with Tara Labs interconnects. Not the best, but certainly not the worst by any stretch.
But for some reason, especially with Mahler, I find myself more attracted to superior sounding recordings versus older, "classic" ones. It just gives the music more impact in terms of climaxes, realism, and attention to detail in his brilliant orchestrations. Case-in-point: M2 with Mehta vs. any number of newer recordings. The Mehta is certainly great for its age, but there are moments that bug me when the sonics cannot handle the impact of the music, and those moments distract me. Same with the Klemperer - great for its time - but it doesn't impact me. Bernstein DG for example is not the greatest soundng recording of all time, but is good enough that I don't find myself yearning for better sound, and I only hear the music.
It's one of the reasons I love the Chailly, Gielen, Boulez, Tilson Thomas, etc sets - they all sound very good to exemplary, and even if there is a musical idea that I feel is conveyed less-than-ideal in my view, great sound can make it more palpable if that makes sense.
This extends beyond Mahler obviously, and more modern composers such as Stravinsky, Bartok, Ligeti, Messiaen, Ives, Webern, Kurtag, etc. also benefit greatly from improves sonics.
