I received my DP-X1 last Friday. Have been using it for sometime, and tested the USB host feature with some external USB DACs.
Here is the list of USB DACs that I've tried so far that are compatible with DP-X1:
Chord Hugo
Chord TT
Chord Dave
LH Geek Pulse XFi
ifi micro iDSD
Since IMHO the stock Onkyo player UI feature is rather poor, no File Explorer, no automatic playlist (recent, most, etc.) I tried to get compatible 3rd party players for Android, but so far no luck. All exhibit a kind of distortion that noticeable on some soft passages of music. Especially noticeable using my test track to test bass response:

This is the comparison, recorded output of that track, using UAPP and Onkyo stock player:

I tried UAPP, PowerAmp, and Google Music, all exhibit similar distortion on that track. Only Onkyo stock player sounds clean for that track.
Any advice for good 3rd party player for DP-X1? If possible those which can do variable sampling rate, and doesn't resample the audio files.
Thanks!
