Hallo, ich benutze den Empfänger an einem Logitech Transporter. Allerdings nur Stereo. Der Empfänger verfügt über apt-X Folgende Info habe ich im Web gefunden: "Theoretical transmit rate of Bluetooth is up to 11Mbit/s current audio encoding theme use only just trivial partition of that. A possible option is Apt-X Enhanced that is compatible with 5.1 channels audio signal through Bluetooth method and has already been adapted into Cinema Surround Play-Out Systems (5.1). Maybe in the near future, we will find that bluetooth creates an inexpensive wireless surround experience approaching that of an actual movie theater with this more promising apt-X Enhanced audio codec. But now you have to switch to wifi to get a real practical 5.1 wireless surround system."

Hello Saplement. Power is via USB... i.e. if your receiver has a USB port, you should get the juice via it. Digital output is not optical (S/PDIF) but coaxial. No analogue output either. It works with any receiver because it is a standard output. Aptx yes. I think it's good that it doesn't have any bells and whistles like an analogue output. Everything clear? :)
