Nice system you have there. The Mansfield Beech looks great. Anyway, I sure hope that you can play SACD's as well as DVD-A because there's a lot of great titles in both formats. For DVD-A I strongly recommend
Porcupine Tree's In Absentia They really are one of the best bands that no one seems to know about, but everyone I've introduced them to has really enjoyed them.
On SACD here's my list:
Pink Floyd Dark Side of the Moon (of course)
Dvorak: Symphony no 8 & 9 "New World"
Holst: The Planets
Dredg: El Cielo
Nickel Creek: Nickel Creek
Hope that helps and enjoy those Axioms.
