Overall, the system makes itself a high-quality impression, and the sound is really great! What I have to complain about are the connecting cables: they are just junk. Had constantly noise and short notes dropping until I bought myself new shielded cables. In addition, the system has NO digital 5.1 input, making the surround effect for me is pointless, because none of my devices an analogue 5.1 cinch output has .. a D / A converter surround unfortunately costs more than the whole system.
