Greetings all, I am thinking of purchasing either a Yamaha RX-V663 or RX-V665 to use as a HDMI input pre-amp between a Samsung BD-F5700 Blu-ray player and a Yamaha HTR-5760 7.1 receiver for a bi-amped 3.1 stereo plus center channel set-up.
I was using the front left and right and the surround RCA inputs for the stereo treble and woofer channels from the electronic crossover and plan on using the rear surround channels for the center channel. This is my main music setup I am adding a center channel to for movie watching.
Both command the same prices on ebay, so, which would be preferable? Does the newer 665 have anything the 663 doesn't that might be desirable? I do not need 3D, blue-tooth, sirrius radio or anything like that.
Eventually, I will find a HDMI to 7.1 RCA audio out converter to take over and use the new receiver for another stereo system. The 663 has 95 watts @ 20 Hz to 20 kHz, 0.06% THD, 8 Ω and the 665 has 90 watts @ 1kHz, 0.9% THD, 8 Ω. I assume the 663 is the better amp used as a stereo devise. Any thing wrong with using the 663 over the 665?
