Wow indeed! I have:
Goodbye Yellow Brick Road - in 5.1, excellent sound and dynamics
The Stranger - 5.1 Joel. Very nice.
My Generation - classic album. Moon's drumming is alive.
Tommy - see above. SACD version sounds better in my opinion
A Night at the Opera - Brian May's guitars in the surrounds! 39 is the best song ever. Its DVD Audio
Getz/Gilberto - lush vocals (not to mention Getz's sax, oh man)
In A Silent Way - First fusion masterpiece. I highly recommend this album. Its the mood of a late, rainy night.
#1 Record/Radio City - Classic Big Star. Turn the treble down for this recording however. Its a little harsh.
Various Dylan re-releases - Blonde on Blonde is in 5.1!
Dark Side of the Moon- Duh. 'On the Run' is awesome.
Halloween - Classic live Frank Zappa. DVD Audio. Highly recommended for Zappa fans. Its an awesome live sound.
Sea Changes - acoustic guitar on this Beck DVD Audio has impressive sound
