The very big advantage: it takes significantly less space than my old system. First, we have connected only the pure 2.1 system. The sound is a little thin, promised by the virtual 5.1 sound, we have not noticed. Can also be due to our living room.
Then I have my old center box yet connected and lo and behold: significantly better sound. Is really fun!
The tracks are automatically recognized via HDMI, so you need not do anything more. Also the looped through to the TV image of the PS3 is perfect. From the power supply can not hear anything. Class is also the "Late Night Mode": that pleases the neighbors if everything is somewhat muted.
Conclusion: The new formats are recognized directly and the sound is excellent! But I recommend at least 3 boxes to connect. I'll sell my old system in any case.
