I did a lot of research and ended up buying the Sony dn1080. It has plenty of power and makes my Polk speakers sound better than ever. It supports hi res audio, Bluetooth, wifi, streaming music apps, 4K and Dolby Atmos, along with many other options. I absolutely love this receiver and a plus for you, the price has come down since I bought it 2 months ago. I switched from denon to Sony and am glad I did.
