I have the Klipsch Reference Series 7 speakers. Which do you think is better for powering the speakers? In A/V receivers: Rotel RSX-1065. Marantz SR8200. Marantz SR7300. Denon AVR-4802. Denon AVR-3803. In amplifier + preamp/processor combo: Rotel RMB-1075 + Rotel RSP-1066. So, which do you think will be best for the speakers? By the way, I CANNOT audition the amplifiers and A/V receivers, that is why I am asking your opinion. My priority is home theater, but I also want excellent music performance.
