catbrat, i looked through the manual for your receiver. as far as i can tell, it only converts DSD to PCM, it does not support true DSD to DSD playback without PCM conversion.

for example all of my Onkyo receivers support DSD in and DSD out without conversion. i think yours only accepts it in and then converts it to PCM.

anyone else is welcome to chime in on this. that is what i've gathered from catbrats receiver manual.
