I am unable to play multichanel 5.1 DSD 128 though ... are you ?
Nope (due to hardware limitation), I have a stereo DAC not multi channel. Although I have multichannel SACD materials all the way to DSD256. I could be able to play multichannel DSD but output is still Stereo.
Tried the test also.
Removed my DAC and played thru the Internal Media Player and Neutron some .dsd , .dff and sacd-iso materials: NADA (for now, for they say a firmware upgrade is in the works)
The internal Media Player can't also see the files. Neutron can't play it.
