gonk - thanks for the reply.

I agree with your last statement re: Blue Man Group. I think the 5.1 vs 2.0 mix is a mastering issue.

Re: toom much bass in multi-channel modes. Is it possible that the bass management in the 990 is summing the bass frequencies from all speakers below their respective cross-overs in such a way as to cause the bass emanating from the subwoofer to be (relatively) too loud? I'm assuming that the bass frequencies from the original 2-channel source are split and sent to 5 speakers (fronts, rears, center) prior to the bass management - and then bass managed to send the bass frequencies from the 5 speakers to the subwoofer in an additive manner. Would this cause the issue with the bass emanating from the subwoofer being too loud?

Thoughts?

Thanks in advance!
