Nick,

Do you mean that if you convert DoP to DSD then ID41 will play it? Or are you playing the converted DSD files over USB or similar?

It's very odd to me that it's input specific too. ID41 and complete, headless, Sooloos integration is one of the best reasons for 818 ownership, imo, and it would be very desirable if it handled all file formats in a music library equally for proper integration.
