There is a Douk Audio C100 Pro Mini... has USB drive and SD card support.
I was thinking about one of these (my old FiiO X3 III is getting on) but am now waiting to see what comes of the S3 and S3 Lite.
This is all great news. I was looking at DAP options to peer with my ZH3 DAC and now it seems being a little patient might be the best decission.
Looking forward to the S3 Lite and S3 Lite Ultra (has a screen ;) )
