The difference is amazing. Like HomeDad said, it's crisper. The highs and lows are much more defined. The electrical crackle in the opening scenes of the Matrix movies on HD-DVD is quite nice. Much more defined than the DVD. Remember, high-def audion is not compressed. It's not as big a difference as going from MP3's to CD's, but's it's darn close.

It's like 7.1... Once you experience it, it's hard to go back.
