The TEAC UD-H01 USB audio DAC delivers high-quality sound. It features a variety of inputs and outputs, supporting a wide range of audio formats. This is a one-owner unit, used until the day before, but I'm selling it because I upgraded my system. I don't believe there are any noticeable scratches, but please check the photos.
