Lifted grounds- No more FM distortion on Tuner

I just realized that my FM reception is 100% perfect now. I recently got a pair of Rogue M120 Magnum Monoblocs and lifted their grounds. The Tuner and the pre is grounded. Prior to this upgrade the Tuner would have lousy FM reception and would get better in the late evening. Before the upgrade my integraded and all other components were grounded. Was I getting a ground loop which was affecting my Tuner reception? Why did this happen? What causes the ground loop?

Buckingham, stranger things have been known to happen. Just be glad that you were able to get the problem resolved.

By the way, have you tried grounding the amps and lifting the preamp, tuner and other sources ? Some say this works better, but i think that it is very system and component dependent. Sean
