Comments: No issues to report in limited use over 3 days. Have not yet played DSD/DSF so cannot comment on the reported issue with those file types. Prior testing on my office system with JRiver as the player had no issues with DSD/DSF playback. Have the board installed in a 3D printed case but have picked up an aluminum chassis and prefer that look. Will be testing on x86 Mini platform I just purchased.
Buying Link: I bought it at Amazon. There are other sources and pricing seems to be level across all sources.
