For my tests, I was in parallel, but I avoided playing anything very loud.
BTW, once the second center arrives, it will be connected to new amp, not to Onkyo 805 (Alan and JC must be smiling now!)
I would love it if you could tell me if the additional VP150 makes a big difference or not. The $400 or so price tag is not a huge deal in terms of my decision factor. If it sounds nicer, I wouldn't mind getting another one. *BUT* I would have to put them side by side. That probably wouldn't be as good as one on top of the TV and one at the bottom....what do you guys think?
I may seriously pull the trigger on the amp. Like I said, I can never use the power...but still. very very tempting!!
