Soix,
The 3 HSUs would run about $1,300, which isn't bad. But looking around the SVS outlet site, I can get 2 SVS Ultra Bookshelves and the Prime Center for about $1,500. Seem like a good value for those speakers.
I'm just running a Marantz 1608 receiver (50 watts per channel, across 7 channels). Is that going to provide enough juice to run the 3 SVS;'s and a couple of surrounds? Looks like the sensitivity on the speakers is 87 db. I have an HSU powered sub, so that should be fine.
Thanks again for the info.
