Just moved into our house that we had built. When we went through design I opted in for their 5.1 system. I am not sure of the brand, but I have 6 6.5 inch speakers in the great room. 3 in front and 2 in rear. All wiring has been pre-ran, including the sub. I'm assuming they didn't use the highest quality speakers, but I don't know. I was looking at the Denon AVR-S650H or the Yamaha RX-V385BL receiver. To me, looks like the Denon would be better for HDMI options and Optical input. Is there pros/cons to going with either one, other than the price point? Also, will I need to calibrate them? I also have 2 speakers ran on the patio controlled by a "dimmer" switch for volume, not sure how I would hook those up to use separately and/or together for regular music. Appreciate any help, I'm completely new to all of this. Let me know if any more info is needed.
