Topping A90D XLR bleeding into RCA?

[maynardewm]

Hello, I just noticed today on my Topping A90D headphone amp that when I set the output on the front panel to RCA, and something happens to be connected and playing through the XLR input, I can hear a little bit from the XLR bleeding through. It's quiet but definitely audible. Why would that be?

I've got a silver and two black A90D's and never came across the problem. Current firmware is 2.6 so I'd check it just to make sure you're current. The most likely thing would be the RCA cables. If they have poor shielding it's possible they're picking something up. Do you have any other cables to experiment with? Just trying to toss out a few things that don't involve shipping or opening the case
