Nuforce STA200 issue. Rumble every couple minutes


I just picked up a used NuForce STA200. 

I have it connected to a low gain tube amp, ~6db

If I let it sit there with no music (same with music) it will cause a major 'rumble' and the speaker driver is pulsating like crazy for a couple seconds. 

This happens every couple minutes. 

Any ideas?

I’ve found my STA200 works best with a Schiit Sys., a combination MrDecibel mentioned in a thread a while back.  I don’t think I’ll ever sell this amp.  It just sounds too good when paired appropriately.
