This is what I am considering. I am using a receiver as a pre/pro with a 5 channel amp. I recently upgraded my mains and now have a pair of bookshelves sitting idle. My surrounds (bipoles) are currently located in the back corners. What if I move the bipoles to the side walls and add the bookshelves to the rear wall and power them with the amps in the receiver. Does anyone else have a setup like this? Did it help the surround field or is it overkill in the surround channels? This will also be a start for a future upgrade to 6.1. Any comments or suggestions would be appreciated.
