Reproduction quality is amazing. But we need Windows 8 32-bit install ASIO4ALL to get his moreover remarkable. Windows 7 32-bit, no problem. I have not yet connected to the HIFI (Tube Amp CAYIN ELAC JET + 330) but I expect a pleasant surprise. No interference, no breath, total silence. On the headphones (Sennheiser HD600, 300 ohms, twelve years of age) listening pleasure is total on FLAC files in particular. Even the 128 kbps MP3 is transfigured under FOOBAR 2000 (the other tools do not offer the same transparency, including VLC). For the DSD, it must go through a manipulation well explained on the manufacturer's website (FAQs) but is on a conversion to PCM. In this price range, it is not yet possible to do otherwise. Finally, a more than satisfactory product that I bought after reading the only review on the site, but very complimentary. Would recommend without reservation.
