One of the best dongle dacs on the market. You don't see these for sale often because almost everyone that buys one keeps it. I'm only selling mine because I found that the Cayin RU7 pairs better with my Aur Neon Pros. This dongle has excellent transparency and dynamics, and generally doesn't impart any of its own sonics into the music, just presents it as it was recorded. This unit was purchased directly from headphones.com two months ago, and is in excellent condition. All accessories included.
