Topping A90 preamp noise

Didn’t see a topic for the A90 already, hope I’m not breaking any rules by posting this!

Any owners of the Topping A90 here? I’m having a strange issue when connecting my powered monitors (JBL 305) to the preamp. It’s giving me small (but very noticeable) amounts of what can only be described as digital noise. Almost like a static noise floor. The weirdest part is that it persists even when the amp is turned down, turned off, or set to headphone-out. For my sanity, I’ve checked itwith other amps, and it seems to only happen with the A90.

Wanted to check with the community before I RMA the amp, make sure it’s not a persistent problem across the board. Thanks!
