Some clarifying comments:
- All 5 main speakers are home made using very high end drivers (100 % scan speak).
- Dual subs also home made using Lambda drivers, again very high end. Currently powered by good grade 175 watt plate amps. Each sub weighs 100 lbs +.
- Rear center surrounds (2) will be "on wall infinity (average mass produced stuff)

I have already setup a privious full 7.1 system w/ other gear. great for movies, nice filler effect for music but by no means as dominate as the main L/R rears IMO.

I did not realize that logic & and DPL IIx were discrete 6 & 7 th channels (so far the only real argument I can see for powering independantly vs one mono channel). But of course the 950 does not have DPL IIx.

I do have the ability to re-configue the subs anyway I chose. Currently powered by good grade plate amps 175 Watts into 8 ohms each, etc. I suspect the outlaw is a slight improvement.

The real motivation is:
-to reduce sources for gound loop hums *****
-reduce weight of subs
-don't want to blow a fuse every time I watch a movie, as I currently only have a 15 amp line and way too many amps/tv powered by it.

I just think the 200 watts each for two rear center speakers is a waste.

I am running the wiring in my new house this week and will wire both rears independantly so that I can power seprately if need be . . . .
