Outlaw 7700
DefTech:
BP 20's main
2 deftech subs
clr 1000
BPVX rear surround
BP2's side surround (soon to be upgraded to BPX's)

assorted reel to reels(TeacX-2000 & x-700/cassette (Teac c3x)/turntable (Denon dp47/Denon dvd 2200.

I may be imagining things, but the speakers seem to sound a little bit "brighter" and surround sound seems to blend in better. I had two differnt amps (onkyo and adcom) prior to this system. Been playing around some with Dolby IIx music. It seems to work better on some CD's then others. 7 channel stereo sounds pretty good to me however.
