My ONKYO Receivers of 2011 was not distributed evenly able stereo concert DVDs / BluRays so here the tone was issued only two front speakers + subwoofer. This fills the space not with sound. Concert room feeling completely missing, So it sounds stupid and not fun. Most receivers are not capable of a stereo signal to be distributed to all 5.1 speakers. I have therefore decided to use the Yamaha RX-V475 Network AV Receiver. Yamaha receivers have a 5.1 Enhancer which one precisely solves this problem. Sounds great and you immediately feel as if you stand in the middle of a concert hall / sitting. That's how it should be! Cool is also that you can take control with the Yamaha mobile app. So settings are very easy to customize. On TV, via HDMI, settings but are also manageable, so you can quickly get to your destination here also. Conclusion => Strong unit with great extras and many connection options.
