Thank you for the reply.
I did try with shorting pins removed, and the hum was even louder.
I get the same hum (with shorting pins) from Mojo, iPhone, and Pono
Even with no device connected, simply moving around the disconnected RCA cable creates very audible noise (confirmed with multiple cables).
I should say that when connecting the Classe via single ended RCA to a preamp, I get no noise (clean as expected). I'm wondering if the amp may require a proper preamp (loading?)
