What is the best sounding Mahler symphony cycle?

I agree with the BIS, if they ever made a bad recording I've never heard it and BIS is always my go if sound is primary.

Who ever produces this label is the very epitome of good taste.

Schubert...BIS is very mysterious; their website says that Naxos is their distributor. Have you ever made a purchase?

Just saw the Zander is recording the Mahler 2 on Linn. Called a "new partnership." Not really a huge fan of Zander, but a Mahler 2 on Linn is going to get my money. Late September release in GB, probably a little later in the US.

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.

A definitive answer to the OP's question of audiophile quality is any of Zander's Mahler releases on Telarc. Although, I wouldn't consider Zander a top Mahlerian conductor, the Redbook CDs sound superb.
