After a long search for a cheap but professional audio digital receiver I discovered this Sony STR-DE497! This is an older model, but always towards the receiver has cost nearly 400 euros 5 years ago, the match he is also equipped with all the a - and outputs you need (of course without HDMI, which I really did not disturb, because There are 3 digital inputs: 2-optics 1-Coax, thus sound reaches the best quality) Decoding from stereo to 5.1 works great, but you get the exciting sense of a real cinema! But it can of course even more, the technical data can be found on Sony-page!
So, I am fully satisfied and would far prefer to swap the system!
