I asked this question over at Audioholics and the only response was "do a search". Well I did for about half an hour and never got a straight answer therfore, I must be stupid. At least that is the feeling I got from AH forum.
I have a Pioneer Elite VSX-01 thx that claims 110 wpc in stereo and also 110wpc in 5.1 mode. (doubtful)
I have some RTi A7`s on the way and my plan was to bi-amp using the surround back channel. I get about 50/50 as to wether or not that will provide any benefit. Some say just bi-wire OR buy a seperate amp. Yes, I most likely will buy an amp, but in the mean time, which method will get me the best from those A7`s for now.
Bi-amp w/surr back channel, bi-wire OR just go old school with one cable and do nothing until I can afford an amp.
