Given the quality of the speakers and amp, I think the 7705 will be a significant bottleneck to your overall performance, and especially for music. I’d either upgrade to an Anthem AV processor or add a good stereo preamp with a HT bypass so the 7705 is completely out of the loop for music.
In fact, if you decide not to use a center channel, which could very well be a good choice depending on your room setup (as mentioned earlier it might be a great idea to start with just two channel first to see how well that works), you could ditch the processor altogether and just get a good stereo preamp and plug the HDMI directly into the TV. Sometimes simpler is better. Best of luck.
