Property me this unit gained since I had the Blue Sky EXO 2. The system is so good that even keinste disorders are reproduced from the loud talk to my very high-quality monitor sound system spec. Since I use an internal sound card on my PC arise in Festplattenzgriff disorders audio board, since it is not specially shielded. These faults are then amplified and played through the monitor speakers. The solution was simple, U Control connected and already all noise were verschunden. Perfect crystal clear sound exactly what I had imagined. Of course you can also in a new sound card inversely animals this would have been far more expensive than this very good solution. From me there are 5 star for the device works perfectly :-)
