I'm upgrading my av receiver. My current receiver is the Denon avr 1911. It's been decent for my needs but I feel that it's a bit underpowered for my 5.1 system. I've got 2 jbl studio series towers, the center, two surrounds, & a powered sub. I would like your input/opinion on what might work for me. I'm looking for another 5.1 setup. Would like to have the latest wifi, Bluetooth, hdmI capabilities. I've done some research on my own. Does anyone like the new Sonys? What about the Yamahas? I was thinking I'd just stick with Denon but maybe I'll switch it up. I listen to hd flac often and really want a great receiver for music & some movies. Any help is greatly appreciated. Thanks.
