I am brand new to this forum, and came here looking for some advice. My house was hit my lightning and my Yamaha DSP A970 surround sound receiver was partially damaged; the sub-woofer channel no longer works. I was using it with a SONY 65" big screen TV. Here are the speakers I have: One (1) Definitive Technology C/L/R 1000 center channel speaker, (2) Definitive Technology BP20 Tower Speakers, (4) Definitive Technology BP2 middle and rear speakers, and (1) Paradign PDR sub-woofer. I have been unable to get the reciever fixed, and I need to buy another one. What would be a good choice for me with the speakers I have above?
