I have avr x2700 and it is not so good in my opinion. Heos without Deezer hifi support, anyway for listening the music is terrible - CD, phono and Heos useless. After 1 year of settings (stereo mode), I also bought the MultEq application, I came to the conclusion that it's not worth bothering anymore and I use an old Pioneer A amplifier that is much better than the Denon stereo music. I had the Onkyo 696, the sound is richer, Thx phenomenal, and the stereo music mode is much, much better than the Denon. The next receiver will be Onkyo
