What is the best sounding Mahler symphony cycle?

If you are looking for high quality audiophile approved recordings, MMT's performances are easily some of the best CD's available. As with everything else, however, his performances may or may not be your cup of tea, but I too can recommend his 5th. Zanders performances of Mahler on Telarc are also excellent recordings and include a CD in which Zander discusses the symphony.

Performance wise, if you like your Mahler a little more expressive, consider either Bernstein cycle. You can't go wrong, except with the Vienna Phil set on DG you may want to substitute out the 9th for his recording of it live with the Berlin SO recorded live in 1979, an outstanding performance I think!

Robsker, I didn't realize you wanted reco's on Mahler #1. There are a lot of excellent #1's, in fact I think it is one of the easier to perform, record, and listen to. But, that said, if you haven't already pulled the plug on this, do consider Zander's #1 on Telarc, and not just because of it's recording but because of it's disc mate Lieder eines fahrenden Gesellen sung by Christopher Maltman, a fine performance of one of Mahler's orchestral lieder.

While I'm sure there are quite a few recordings of either piece that folks might prefer, none will be found together on CD that I am aware of, and to my ear both pieces fit together as if there were meant to be heard as recorded here. It gets a lot of play time at my home.

And, if you are late to come to Mahler's lieder, its is a great piece and recording to start out with.
