What is the best sounding Mahler symphony cycle?

MTT on SFSO (SACD) His 5th is excellent.
Abbado on EuroArts and Accentus (BluRay) #8 yet to come

Many (perhaps too many) excellent Mahler sets but you get to choose.

I can, unabashedly, say that I have heard most of these and find something appealing in almost all of them. However, the OP was asking for "audiophile quality" and, for me, that means a well-balanced and high resolution recording. This eliminates all the Bernsteins, unfortunately.

However, the Abbados on BluRay are superb in every way as are the MTTs and many others on SACD (Chailly, Boulez, Jansons, etc.) Zinman doesn't move me and the sound is only OK, imho.

I would put none of the ones you mention in the category of "best sounding" although they each have their felicities with regard to performance.

Hey, Yu11375, I was trying to keep this on-topic and was not criticising your general recommendations.

My love for Bernstein's Mahler knows few bounds. His NYPO M2 turned me on to Mahler and his late 6th DG is, imho, unsurpassed. I will never forget his last performances of the M2 and Das Lied von der Erde with the NYPO.

I also treasure the Sinopoli, Kubelik, Neumann and Boulez recordings (and I did mention Boulez' more recent ones on SACD).

However, aside from the recent Boulez SACDs/BluRays, I would not recommend any as "audiophile quality" and that was what the OP asked for. If he had not made that qualification, I would not have commented on your post.

BTW, there is a spectacularly-recorded set being made by Marcus Bosch on Oehms. Some are, also, excellent performances. And I second the recommendation of the Zander/Maltman recording.
