Ghasley,
Thank you for sharing info on the Playback Designs MPD 3
When did it start shipping and what is the current price?
Currently I am using the ExaDevice's ExaU2I and their lo-Tech DSDDIFF player mated with Korg Audiogate for 1 bit/5.6448mhz DSD playback; a stable DIY solution.
It's great to see other product options emerging for DSD playback.
