Interesting - I had been running a core on DietPi X86 on Debian AMD64 with an i5-6500 and even up sampling to DSD512 to a Ropieee based RPi with no issues - just to see if it worked.
Maybe that would be thinner than a windows based NAA on the same hardware. But running Ropieee with RAAT passing DSD512 (LAN connected) works fine and is my main rigs setup to an OPPO Sonica DAC.
