HRT Music Streamer 11+ with Aqvox Linear Power Supply.
The Music Streamer 11+ really is a great USB only DAC and is then improved even more with the addition of the Aqvox Linear Power Supply. I was using a Rega-DAC R previously and felt the the HRT was better and this was before adding the Aqvox.
Both in excellent condition (split price below) including UK postage.
