The only thing you get is the Audyssey. If that is a big deal for you, fine.
For years I used to think that Pure Direct is best and that Audyssey is not useful to me.
But once I experimented more, I found that Audyssey Dynamic EQ (with Audyssey Bypass L/R) is a feature I would never do without.
I would never own any pre-pro or AVR without Dynamic EQ.
But I do agree that some people may not have any use for it. I understand completely since I felt this way for a very very long time.
