The 5.1 system is now for half a year in my operation and I can currently see no real weaknesses. The biggest hurdle was the XXL-Sub accommodate anywhere. To build two people there already have been necessary in a Subwoofer weight of 30 kg. That was worth it! the subwoofer brings to shake the house. Amazing what this thing is capable of. By contrast, the satellites are very very small, which does not mean that they are quiet (on the contrary). Movies, games and music, but also ordinary series is now experiencing very different, but that's the point of such a system. The Decoderstation 5 directs the sound to where it should go. OK then!
All in all a really great facility that is unbeatable for about 600.
To mention is that the speaker cable has never ever served in our 35 m² living room. And considering you rather just in advance which devices want to join it to the decoder station, that you ordered the same matching optical cables, namely they are not included.
