Changes in DAC Presentation - Need Advice


Hey all, I recently purchased a Denafrips Terminator II, and ever since I've noticed that some days the sound is sweet and natural, and other days it is forward and bright. I've even heard the sound change mid-song. Could this be due to fluctuations in my line voltage? Any other reason this may be happening?

System:

Mac Mini running Roon core

Sonore ultraRenu

Denafrips Terminator II

Pass XP-12 Preamp

Odyssey Audio Kismet Monoblocks

Focal Sopra 2

@alvin1118 might have some thoughts.

To check on @mahler123 's theory, have no noticed if the OS/non-OS light is changing status? 

FWIW, I run a Pontus and an opticalRendu, but haven't had your issue, even though I'm in TX in a spot with notoriously wonky electrical grid. When running analog, I find voltage fluctuations lead me to regularly fine tuning the spped read by the tachometer on my turntable. Cheers,
