MIchelangelo,
very interesting the possibility to use content DSD, my doubt is if I make a mistake or not. 
I insert the ISO images DSD64 but when I am browsing the file system using the “Browse” I do not see any tracks. Does the function expect the files in a specific way? Or is the function still in progress?
Using a PC with FOOBAR and the same DAC all the songs are perfectly recognized
Ciao
