Hello, Well I got my Sony receiver from UPS today. I set it up and did compare it to the H/K 520. I have only played with the Sony for about a few hours. However, it to me sounds better. The sound is a little more detailed and full in both a home theater and music environment. I will post more later. But the only thing I am disappointed from the Sony is the lack of on-screen display showing volume and input device (Unless I am missing something?) The H/K did have a better on-screen display. So I think what I am just wondering is maybe I have something setup wrong and there is a way to turn on the volume display on the screen? Well anyway, I will report more later.
