as a company with direct experience with roon's hardware as well as most of the major servers out there the titan would never be my first choice the first nucleus was a cheapie nuc in a nicer case
compare this to an Innous or 432evo servers:
Innous uses a massive internal high end power supply
432EVO uses two external sbooster power supplies
432EVO also uses a separate clock and USB card as well
so compare the Titan probably uses a wall wart like the nucleus,
isolated USB not apparently,
clock technology also seems missing.
roon makes great software they don't know anything about designing stat of the art hardware
