The HRT Music Streamer 2 plus is a great USB DAC. The asynchronous DAC makes all the difference, effectively resolving clock speed differences.
I purchased this new ~1 year ago, and have really enjoyed it. A critical component for any hifi system with a computer as a source.
Installs instantly on Windows 7 without any setup.
I will include shipping at my asking price, and I will cover Paypal fees. The sale will include everything originally included with the device: Music Streamer, documentation, original box, and original USB cord.
