As my title says, I am of this Reciever just thrilled! In connecting a Sony Bravia TV'S and a vicious surround system, an absolute monster in terms of sound. Since I "Teufel Concept E 100" use one, it would be good to note that there are no problems there. The subwoofer of this system is simple as usual subwoofer via the sound input by a mono RCA cable is connected and can then (in my opinion) only really play out its full potential! As this vicious system "only" a 5.1 system, I ordered 2 more satellites "Dynavox" also here at Amazon. They serve as additional rear left / right surround speakers and for that they are perfect (not only from the price). Thus, I have a fully compatible (DTS, Dolby etc.) 7.1 Surround system, which simply prints out only legendary sound! This Reciever done a wonderful job with the bass, middle and treble totally clear to come over and give a brilliant surround feeling.
Only just "Transformers 3" looked in a 7.1 audio track DTS HD and flown off the stool: D just awesome ... merh must and I can not say :)
