Sorry to be thick, but how do you "lift ground"?
I have a hum with a pair of EvO200.2's running as monoblocks into a Sunfire Theatre Grand. I never had any humming until I changed speakers (I replaced my Jamo E870's with a pair of Audio Physic Libra's). The Jamo's were biwired and the Audio Physics are not, that's the only difference between the non-humming and humming systems (although I have not gone back and replaced the Jamos to see if the humming persists).
Any ideas?
