Other stuff simply comes across so chopped up, I wonder if I shouldn't just listen in stereo to get the best of it. But I'm usually too lazy to get up and walk the 7 feet to make that happen, and I have a hard time while in my listening room just hearing stereo, regardless. I feel kind of like my room is partially void and my backside is naked.
You might try the (usually ignored) Hall mode on the QSD-1. It is un-processed stereo in the front chs & nice indirect ambience from the rears. Usually for stereo I preferred the QS Synthesizer , but the Hall mode is a nice choice between bare naked stereo & enveloping surround.
Taking the initiative to get up and push the button is another matter...
As I said earlier my set up sweet spot is Exhibit A, but with a couch directly between the rear speakers I can also do "B" for casual listening. It gives a very wide 180 deg soundfield but no real surround coming from behind. On my PC work station about 5' behind the couch I have two, 6.5" two way speakers, decent quality. At times I have hooked them up very simply to the main rear ch speakers in the well known L-R and R-L design. It does a surprisingly good job of filling in depth when sitting on the couch. But the front soundstage is still noticeably contracted.
