I've been reading through the forum concerning these two amps and still haven't fully made up my mind which one to go for. For the time being I'll be sticking to 5.1. The deciding factors are: I want to bi-amp my main front speakers which should improve the stereo mode sound (I hear the 2011 is not so good in stereo but was that bi-amped). I like the easy set-up function of the 2011 but is the 3803 still easy? I like the function on the 3803 that can improve lip sync (I have an early Pioneer DV-717 and Sky seems to be broadcasting out of whack a lot these days) I would prefer it in black but the 2011 seems to be silver only. What is the difference in quality between these two in all surround modes? Any other help would be appreciated.
