As for the sound and looks of the plant is really great - the best I had so far for my PC. The only negative point is the noise and whistling the boxes if no sound signal. Once sound coming from the speakers, you can hear nothing. But there is no sound and the speakers are on, you can hear a whistling of the two boxes. Going to get closer to the boxes with the ear, you can hear a noise additionally. The noise is unfortunately silent listening in silence in the room even from afar.
Since the noise is even listening when the speakers are connected only to the power, I assume that the noise is caused by the pits and not from an interfering defective sound card o. Ä. At first I thought that I got delivered possibly defective boxes. Thereupon has sent me new Amazon. Unfortunately here also exactly the same problem.
Conclusion: If the noise and the whistling would not, I would keep the system immediately. The visuals are great, to regulate the sound super and very good. In the long run I do not get along with the two "noise" but why I will send back the two systems unfortunately.
