From what I've been reading so far, it sounds like the A2 is good but doesnt' have coax digital or analog multi-channel out. The XA2 has that and 1080p. The A20 only has the 1080p, but otherwise, same limitations as the A2.
I have a Sanyo PLV-Z4 720p projector and an old Marantz SR-18 (or was it 17, I forget) used as a preamp. So direct would probably help me, but 1080p would not.
I'm most interested in quality of regular DVDs. I have a couple hundred and would hate for them to go down in quality.
From everything I read, it seems like its best to skip the A20. Either get a bargain with the A2 or spring for the XA2.
But I haven't made up my mind, so keep those recommendations coming!
