I went from the 990 to the 2807 because I needed HDMI audio/video switching capability. I don't use the amplifier section of the 2807--I just connect the preouts to my Outlaw 7700 amp. The sound quality is OK but maybe it's just my ears... the sound isn't quite as
rich as the 990's was. (Maybe it's just not quite properly tweaked... who knows.)
One thing I definitely do NOT like about the 2807 is a lack of balanced outputs. Now, I know a lot of people claim that balanced outputs make no difference, but they definitely make a HUGE difference in my house. I have a lot of dimmers that cause a terrible
bzzzzzzzzzz on my monitors that I never had when the 990 was connected to the 7700 via balanced outputs.
The moment the 997 is available I'm selling my 2807 on e-Bay. In this economy I oughta be able to get @$200 for it.
