I purchased a SIT-3 in 2019 as a demo unit. It sounds beautiful for some hours (today about 5-6 hours), but then it sounds tinny and distorted. It's an odd sound I don't know how to describe. The left and right sound sort of separated and the mids receive. When I switch to my Moon 240i, the sound goes back to normal, albeit lower fi than the Pass Labs. I'm driving it with a pc feeding into an RME ADI-2 DAC. I thought maybe the computer was causing an issue for the DAC, but I demod an Innuous Phoenix reclocker, but that has no effect positive or negative. The speakers are Harbeth P3-ESRs.
I bought it as a demo from Refined Audio in the U.S. in Oct 2019. My belief is that since it was a demo, I didn't have a warranty; I don't believe I received any warranty paperwork. Since it's an intermittent problem, with at least some parts no longer manufactured, I'm concerned as to how/if I can get this repaired. My first question is if this is a known issue. That would help a lot. Second question is best route to pursue a potential fix. I haven't yet contacted Refined.
Thanks for your time.

Couple of possibilities
1) The thermal switch is being activated
2) Possibly dc offset or biasing issue
Is it always ok when it is first turned on, or is it now permanently affected?

I don't know if it is a 'known problem' but I have not experienced that myself.
Since the FW products are now built at the PL factory, you might also want to
contact customer service at PL on what can be done. Tell them your situation
and the serial number of your unit.
I hope you can get this resolved soon.

It's always ok when I first turn it on. I did contact the dealer, and they said it has a two year warranty and might be a power supply. They put me in touch with Pass Labs, and they will take it for repair. I'm impressed with the quick response with Refined Audio and Pass Labs. Hopefully, they replicate it successfully on the bench! Thanks for the reponses.
