K, if you're expecting to constantly be getting "umph" out of your QS8s(or any other surrounds)you may be disappointed. When I listen to classical CDs on my surround setup using DPLII the surround speakers reproduce relatively subtle ambience effects extracted from the stereo channels. This helps create a more realistic sense of the concert hall reverberation, but definitely no umph. Movies at times put specific sounds into the surround channels and so do some multi-channel DVD-As/SACDs with pop music, but often there's little or nothing going on there, so again, don't be expecting to be constantly hearing heavy effects.
Hopefully you got the microphone with your 3805. It'll do a fine job of automatically calibrating your speaker levels and delays and equalizing some of the room problems.
