Oh, I see what you mean by the room & Pure Direct mode - if the room is bad, you might need Audyssey. But since your room is good, you don't need Audyssey. Same here.
I bypass Audyssey, but use DEQ for the subwoofer bass.
Did your friend buy the
Audyssey Pro Kit (used in
IMAX cinemas and
DARTs systems) or is he using the standard Audyssey like most people?
