Scientific Audiophile found RCA output issues?

British Audiophile reported a similar issue with the WiiM Ultra:

No, he is talking about the RCA line input.

I’ve had a Pro Plus since November 2024 and have not experienced any discernible noise from the RCA out to my Sony 590 receiver, with or without using my Schiit preamp. And, just listened to a CD using an SMSL PL100 line out to the Pro Plus line in and sounds just fine.
