As far as I know DSD is only available through USB.
Chris would have to answer on the down-convert - why would you want that to happen?

James,
Would like to get off the USB connection and use AES/EBU (of course vs. my plain old Windows 10 music server vs a BDP-3 I could change my mind - have had many discussions, mostly via email with Karl S as I've been looking at an upgrade for over a year but have not pulled the trigger). My DAC would take 176.4 and upsample it to double DSD anyway. There's other things beside the Lumin that do DSD (64) on other than USB. The Lumin does it on all the digital inputs:
"Optical, Coaxial RCA, Coaxial BNC & AES/EBU:
DSD (DoP, DSD over PCM) 2.8MHz, 1bit
PCM 44.1kHz–192kHz, 16–24bit"
I was just getting more serious about getting a better player over the last week or so.
