You likely don't have a Ground Loop problem at all.

From description, the "SHHHH" sounds like thermal noise from electronic circuits.

It could be that your X2U USB audio adaptor might be defective.

Might also simply be a bad mic cable in which the shield has become disconnected. Try substituting another
"known good" mic cable.

Also -- it could be that you have things turned up in the playback software mixer that are adding noise. If you are using the speakers to monitor the mic at the same time, that could do it. Headphones when attempting to monitor the live mic while recording, and be sure to turn all other faders in the playback mixer off so that noise from CD or whatever isn't mixing in at the same time.
