Things improved greatly when I added the amp, but the phenomenon still exists.

Do you have or are you adding a subwoofer to your setup?
I DID have a mission 70ASA sub up until last october but the amp inside it blew so I've yet to replace it. Up until now bass levels with my fronts were good without the sub powered by the 2300 - but the 3800 sounds as though bass levels are set lower by default or something, nothing an adjustment can't fix - but on my 2300 I didn't play with the treble/bass knobs at all and the bass was stronger.
