Not OP, but here's my audio stuff in case anyone wanted product recommendations:

  (Connected to PC via USB)
  Schiit Modi DAC
  Schiit Vali 2 Headphone Amp (with a tube!)
  PreSonus E4.5 Powered Studio Monitors

  (Connected to phone via USB)
  Aune Yuki DAC
  Meze 99 Classics headphones.

To my ears, both sound pretty good. Especially on the phone, Tidal hires audio seems to sound better. Although I have not performed any double-blind tests or anything!!

(Mjol / Ygg here, but this is quite far out of scope for OP’s question, which is trying to diagnose a change in audio between two motherboards, and I wouldn’t recommend a heavy stack of gear this early on.)
