Music Hall Turntable Hum?

Thank You-Disconnecting the ground results in a steady low level hum. Audible throughout. My "hum" isn't really "audible" or bothersome until higher volumes of "more bass" and then it reaches a level and literally reverbs. Can't really move the TT without purchasing longer IC's which is part of my question. My BP 2000's have a built in powered sub and if you use the gain switch on them(increasing the bass levels) it seems to reach that "reverb level" at lesser volumes. I have a sunfire 5 ch. amp and pre/processor and use balanced IC's for all 5 channels, mainly because I had this problem with my previous setup(same TT and speakers different everything else) Mr. Hall says I should move. I am using a Panamax and only one component(amp) has a three prong plug.WTF IS IT? Thanks

Thank you Newbee(now I see why I couldn't take that moniker) OK-The hum does increase with volume(stylus off).Can't really hear it at low volumes, but I'd say it "kicks in" around 60% Vol. It then increases notably. It starts as more of a white noise then starts picking up the "hum" as the vol. is increased to around 80% when you can hear it 10' away. With the CD player I can increase the volume to around 90% and not even hear a white noise. Maybe more like air, but no hum. Unpluged the TT and IC's -and no hum from pre. If I take the IC's from the CD player and hook them up to the TT, would that eliminate the IC's from the equation? Don't know where else I can put the TT Thanks again

That I do not know. As I said, I should be Newbee. The Music Hall MMF 5.1 comes with the Goldring 1012GX MM cartridge. Unfortunately, that's the extent of my knowledge. The volume differences between the CD and TT are not that far off. There is some difference, but not enough to think that it's because I really have to crank it on Phono. Could it be a bad ground wire that came with the TT? If I disconnect it it REALLY sounds bad(Hum)Sigh...
