I have been up and running for 2 days, now. Very happy with the sound and interfacing with an old iPad.
The case gets warm, but not hot and no fan noise. Nice and compact.
I had been running with a Peachtree X1 converter. This is an older converter, but the software identified it and works nicely. Today, I tried switching to a Douk Audio U2 Pro. It auto configures it to HIFI DSD, and does not provide an other option outside of the headphone and HDMI. This converter does support DSD and PCM. It starts out at PCM, but Moode switches it to DSD. FWIW, I run the converters on the USB 2.0 ports, and the memory stick on the USB 3.0 ones.
I didn't find anything in the documentation or searches on the forum. Douk says it is compatable with Native Linux with UAC2 (no driver needed). I'm not sure what that all means. If this is not configurable, is there a list of the USB to SPDIF converters that are supported?
