The DAC Magic Plus Cambridge Audio has a great value for money. Premium stereo sound, excellent headphone amplifier detects 44-192khz and is sampling this further on. The catch: the instantly recallable Standard transfer via USB 1 and 2. Windows is maximum choice. It is therefore essential to install on the computer interface: 1. the recommended driver of CA 2. a music player with ASIO and 192kHz compatibility (the vote is also recommended by Cambridge freeware program a little tricky, because directly an additional app must be installed herein for ASIO), and all settings (manual). 3. In addition, the DAC itself must be manually calibrated to USB 2 at power via special function.
