I moved to the 990 from a 3801 and found it a definite step up. I was also always pleased with
the Dennon and still use it for casual listining in the family room.
I'm not up on the feature improvements between the 3801 an the 3806, but the only feature of the
Denon I really miss is the ability to handel a second set of surrounds without jury rigging.
