I'm wondering how these turned out? What have been people's experiences with the Pi with the uDSD in pairing? What OS are you using?
For previous Pi owners, do you notice a big difference with the power supply?
Thanks for the info,
I don't have Nuprime PI server but load my PI board whit ropieee or dietPI or ARMbian(*) OS's and a squeezelite software modded and compiled from source started @ boot with parameter like these:
./squeezelite -n 'uDSD' -r '384000 352800 192000 176400 96000 88200 44100' -D 0:s32le -o 'iec958:CARD=CDP9,DEV=0' -b '12400:12400' -a '499:3:32:1'
the server side (@VirtualMachine PC) runs Daphile (beta) and stream directly to RPI with squeezelite (@DSD128 res.)
I. chain: DAPHILE (@VM PC) --- [LAN] --> RPI (squeezelite-R2) -- [USB] --> uDSD or CDP9 DAC
With another MODS, using circa same software with ARMBian and SPICE protocol, I can stream USB (Isochronous) directly to DAPHILE via LAN using RPI like a bridge for the USB virtualisation protocol..
II. chain : DAPHILE (@VM PC) --- [LAN] --> RPI (USB Virt ) -- [USB] --> uDSD or CDP9 DAC
With this MODS the Daphile VM view the virtualised USB via network channel, and use remote device like a directly attached DAC!
I started using DAPHILE because it support Tidal HIRES but it runs on X86 machines only , the RPI used like a bridge fill the gap because the X86 machine (and coolers) is away to audio gears.
