There's educated audiophiles, and then there's placebo peddlers.
What you encountered is the latter.
The former will tell you that things like tubes are bs. Anything over CD quality is imperceptible. You don't need special cables to carry digital signals etc.

I repeat: you don't need special cables to carry DIGITAL signals.
What does a crappy digital audio cable actually sound like?

Having UPS for computer stuff is perfectly fine and recommended.
Having UPS for your hifi stuff is a waste imo. If I have a black-out, the last thing I'm concerned about is being able to play music. But I've already said too much. I'll leave this topic.
P.S. Not the first time I've heard about things not liking UPS power. Some people will blame the UPS quality when this happens.
maybe my receiver is simply a piece of shit, but going with optical fixed it
