I have a Sony 930, I auditioned it alongside a Yamaha 595 and a Denon (can't remember which, higher price). I was upgrading from a Yamaha 393 (no DD/DTS, just decoder inputs) and the Sony was the hands-down winner for movie soundtracks against the Yamaha and the Denon. There is an option in one of the submenus called "Effect" on the 930 which, when turned up full on a DD soundtrack, makes the sound completely enveloping (echoey on DPL tho') It might not be purist, but is sounds tremendous. That swung it for me over the 595, which, but for that effect setting, was a very close contender.
I did notice, even in the demo room, that the Sony was not as musical as my old Yam, let alone the new one. And the Denon was in another world musically. But in the end I decided that what I really wanted was DD/DTS performance, not audiophile 2 Channel sound. Had I not given my old 393 to my brother, I would have kept it for 2 channel, since it was easily better than the 930. They should be dirt cheap these days!
Be aware that some people hate the 930's remote, but I love it. I hated the 595's. Also, I saw a 940 recently and I don't think it looks as elegant as the 930 it replaces - although there appeared to have been some well-thought-out button placement changes. And I recommend going for the silver finish.
