I have a yamaha rxv1800 and am having trouble, I get a bad buzz through the speakers, yes all connections are good and the turntable is properly grounded to the amp, I have even purchased a pre amp and hooked it up only to make the sound worse and very distorted. Any help would be greatly appreciated I have a feeling it has something to do with the stylus output. The kicker is, all works and sounds fantastic when hooked up to my old pioneer amp.
