I am getting ready to purchase some Yamaha NS-777 floor speakers for a home theater set up. I will be purchasing the rest of the speakers in that same class for a 5.1 surround sound soon. Right now I am concentrating on the floor speakers and a nice Amp for them. They are 6ohm speakers and I will most likely B-Amp them. What would work best for a receiver? Maybe separates? I'm not sure as this is my first home theater set up other than HTIB.
