For a start - spend some time for speaker positioning. It's far from optimal in your case. As you already know - we have a common friend 
Devialet + Dynaudio is a very good match, but if you want/like warm colored sound, this combo is not for you.
What speaker cables do you use? I hope not anything with silver.
About the problem with UPnP - I assume you have tried to pull the power cord from the wall?
Also, why do you use mConnectHD and not BubbleUPnP which is far better?
