If it hasn't already been suggested, is there any possibility for DSD file playback (which perhaps the core could convert to PCM)?

Not sure if it's technically possible, and I know Bob S will likely turn green and his head revolve around at the very thought, but whether it's an inferior format, or not, the fact is that desirable recordings have been and keep being released on it - in fact in some quarters it seems to be growing in popularity - so it would be nice to have an integrated way to play it.
