Is this even possible?

I'd like to see Mezzmo capable of streaming raw DSD 64, 128, and 256 and pass it through HDMI to my receiver (which can decode it). This is kind of a gap in the market, and to do this most audiophiles need to use a computer connected to their system, which is cumbersome.

Mezzmo does support dsf files that contain dsd streams. You can try adding the files to Mezzmo then turn off transcoding to see if they play.
