I used to have to ground my dad's turntable and stereo tuner when 
recording from the turntable to avoid the buzz you are speaking of.  I 
think it was because of a dirty power source.  A line conditioner may 
have helped also.  I had a similar buzz in a custom auto stereo, with a 
lot of watts and an auto line conditioner removed the EM noise added by 
the engine.
