I guess when I am in 2 channel mode I simply prefer right and left speaker only ( plus sub, if connected ). I see 6 channel stereo or 2 + channel stereo as background music listening type things. I'm not sure going back to a "quad" setup ( right left plus rear surrounds or rears plus surrounds ) will do much to localize the sound stage for normal 2 channel stereo recordings. I am not yet big into dvd audio or SA CD's though plan to delve into such soon, but I think what some of the effect they promote is a different soundstage. I can't remmeber how to spell his name but the engineer famous for much of GAS ( Great American Sound ) SAE and Sumo equipment ( James xxxxxxx ) has been quoted as saying sound in nature is MONO, and goes on at length to describe the effects stereo recordings has had on musicality ( I used to own some Sumo equipment and can say it sounded very musical!). So, not sure there would be a huge demand ot remove the center channel. The sound would still be processed by the 950, and if it were 2 channel recordings to begin with I don't see how ANY processing would benefit the soundstage of the recording.

My wish list for 2 channel sound would be the ability to set my mians to SMALL and in 2 channel bypass mode have the bass management feature remain active such that my mains would receive only the bass above my crossover point and that my subwoofer would take the remaining bass. The " double bass" issue doesn't bother me that much in terms of the obvious but it would be nice to remove the low frequency demands from the mains and allow the sub to do it's job of making bass!
