I plugged this unit in my home cinema Yamaha amplifier with an optical cable. I am the User with my tablet Samsung Galaxy Tab Pro 12. There are about 3 meters between the two devices, so no litter problem. Deezer's music is perfectly reproduced and beautiful. Yet I do not use Deezer Deezer premium but free. There it seems a quality difference between the two. Regarding pairing there is no problem and recognition between the two devices is almost instantaneous.
