Don't have a DVD-A or SACD player, but using my DVD player:
1) Celine Dion, A Decade Of Song, PCM, "My Heart Will Go On"
2) The Eagles, Hell Freezes Over, DTS, "Hotel California"
3) THX "Tex" trailer, EX version only (the one with the Tex dropping tools in the surround back channels) or THX "Jungle Sounds" EX demonstration (flies and animals buzzing around counter-clockwise to the listener).
4) Master and Commander, DTS, First Cannon Fight (damage to the ship and crew scrambling about the ship after the first attack volley), Toy Story 2, DTS (opening Buzz Lightyear sequence), or Finding Nemo (Darla tapping on the aquarium).
5) All speakers blending seamlessly (really gotta hand it to Audyssey), build quality, warranty, less glitz and "look at me" fascia.
