What is the best sounding Mahler symphony cycle?

At present , Ivan Fisher with his Budapest is best  in world .

To me the Solti/Chicago set is better than Bernstein.
To my ears the best sounding set, at least on redbook. is the Phillips Haitink/Concertgebouw. He also has the great Maureen Forrester and Ely Ameling not to mention the Amsterdam Chorus.
Haitink is less "sturm and drang" than most which I like better myself. YMMV

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.

Lowrider, Yes I have about 40 BIS CD's -Naxox distributes doesn't make. Buy most in huge used store in St.Paul.

I look for current Nordic composers, stuff coming out of Sweden, Estonia and esp. Finland is fascinating to me.

Just remembered, If you want the definitive Mahler 1, Jascha Horenstein with the LSO is it.
It was on Nonesuch LP for a long time, last time I saw one I belive it was on Unicorn CD.
All his Mahler is fab,I don't remember the sound, if you do find one I bet it ain't cheap.

I'd give $46 for one if I didn't have the LP.
