Works and sounds beautiful (which it does as a headphone amp also) in USB DAC mode. The built-in battery and ability to switch off USB charging also means I can attach it to my flaky old RPi without tripping the USB booby trap pre-built into this Pi model.
Shows as 'iBasso' in the device selection. Can't recall if hardware volume worked, I think it didn't as the device has a hardware vol knob on it.
