I think it's a fine recording, and a good addition to anyone's collection. I have no complaint about the sound quality in SACD which is really so natural that I could close my eyes, and imagine myself in a hall. There are other Mahler 2nds which are better, but not very many and not in SACD multichannel sound. The Litton which I love is actually SACD stereo not multichannel. The MTT is good, but not as much to my taste. I usually find myself playing the Urlicht for Lorraine Hunt Lieberson's singing rather than listening to the whole symphony. we all know about Kaplan's SACD 2nd which is not a good as this one. This one is also head and shoulders above the Abbado which I find underpowered no matter if I'm listening in stereo, dvd or sacd.
I actually like his Mahler 6th also. It's probably the only one I've heard where the Scherzo sounds okay coming after the Andante although I usually program it so that the Scherzo comes second. Again, I find it more interesting than Abbado's Mahler 6th.
