Since I use the unit just as an external sound card with RCA outputs, I can say little about the rest of the skills. As a sound card, the device makes a great sound impeccable. He plays casually with expensive CD players. However, Upsamlefunktion verschelchtert the result. It confirms once again what is not there, is not expected to be added. Guitars sing then strange and the sound is a matter of taste. Maybe suitable for mp3, I have not tried from 44.1 kHz do not like me. But one must not turn it yes. The processing makes a high impression. The packaging is a bit pretentious. The Kofhörerverstärker provides large volume. The value for money is unbeatable.
