Plenty of stuff out there. If you like Beethoven, there's a great cycle of his symphonies (incomplete) on Hybrid SACD (RCA Red Label) by the conductor Paavo Jarvi and the Deutsche Kammerphilharmonie Bremen. I particularly like the very athletic version of the 5th Symphony, but all in the cycle are very good, both performance and audio. The 5th is of course has plenty of impact. It's a really great performance of an otherwise overplayed piece. The current offerings in this cycle are 5 & 1, 4 & 7, and 3 & 8.
