Edit: now sold.
A while back I wanted to experiment with DSD (before the DS arrived, obviously). So I bought a Schiit Loki, which is a DAC optimized for DSD playback. I no longer need it so it’s for sale. Very decent sound for the price and a great way to play around with DSD (single-rate only) if your current DAC does only PCM. More information on the Schiit Audio website is here. Asking US$75.
