I only have a stereo system but the following BluRay discs sound the best to me:
Sgt. Pepper, Chicago Quadio, Stevie Wonder - Songs in the Key of Life, The Doors - Perception, anything remastered by Steven Wilson (Yes, Tull, XTC, etc), Led Zepp hi-def, and the new Japanese release of Miles Davis - Bitches Brew should get you started.....and, as a bonus, double as a stress test for your bank account.
