Music Hall Turntable Hum?

I have a slight hum when I use my phono that increases with volume to the point that when played at loud levels it actually starts feedback with my speaker. I mean bad. System is dead quiet with CD(Music Hall also)I have played ground loop search but think it may actually be something else. Speakers are Def. Tech BP2000 with built in subs and the size of the room and wife dictate the distance I can keep them apart. Are there shielded IC's I could use to prevent the feedback? The MMF5.5 has wall wart plug. Is this EMI? Any help or thoughts would be appreciated. Thanks

Sounds to me like your problem is that your cartridge does not have high enuf output for your phono stage. What is the cartridges output? How much gain does your phono stage have? Your complaint reminds me of someone running a MC cartridge into a MM phono stage.

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...
