Need help in matching avr system with Focal 706S

Hi, I am totally a newbee in HT so I need help in matching a good quality AVR system for a pair of Focal 706S speakers and a PSB C5 central. I will add SW and focal surround later if my budget allows. If not then I will buy those couple months later. My current AVR is Yamaha TXR 6570. I would like to use for mainly music like 80% and about 20% for movie. I do have 3D TV and will not be upgrading to 4K TV for couple years later. My budget is about $800- 1K max. I don't mind to buy used items.

I have a 18F height ceiling living room and 12x14f room. Also the living room is connect to the kitchen area. I am not a loud volume listener either.

Any input will be greatly appreciated for a good AVR which will work great for a cheap pair of Focal 706S.
