When I upgraded my receiver to the integrated amp, I had a ground loop problem. Since then, I've had to put cheater plugs on most 3 prong plugs. It's almost as though it's a different sound though. The ground loop problem before was more of a hum, whereas this is more of a buzz. The buzz does not change intensity when I touch the groung post. The buzz gets much louder when I take the ground wire off. As a test, I went outside and disconnected the cable where it enters the house, no change..
Buzzing source
Just got a new mmf-5 turntable. It is being run through a Parasound phono pre to a Audio Refinement int. amp. The table's ground is connected to the ground connector on the back of the Parasound. when I remove the ground wire, the buzzing gets much louder. All grounded plugs in the system are fitted with "cheater" plugs, then plugged into a power strip which is grounded at the wall outlet. Other than trial and error, does anyone know if there is a main culprit in these grounding problems? Should I be trying to ground the table somewhere else? The buzzing is only occurring when the phono input is selected.
