Good question about the turntable input. I am using just a regular line input with the Sutherland stage. Thanks for your response.
Help! Can't Get Rid Of Buzz in system at Higher Volumes
Help! I currently have a VPI Prime Scout TT with a Nagaoka MP-500 Cartridge loaded running through a Sutherland Insight stage/preamp into a Marantz SR7012 AV Receiver. With the turntable input selected on the Marantz, when I turn the volume to around 50 or above without playing a record, I am hearing an annoying buzz that I am unable to get rid of. This is not a 60Hz hum but more like a 120Hz buzz. I've tried using a Furman power conditioner strip, a HumX from EBTech ground isolator, using two different power outlets for different components, different phono cables, a variety of turntable-to-stage ground wires, etc. The noise is not present when using other Marantz inputs. The only thing I haven't tried is installing a coaxial isolating transformer for the coax cable coming from my DirectTV satellite dish (I doubt if this is the problem as I don't notice the noise when the TV Audio Input is selected) and disconnecting a dimmer switch (on the same wall as the A/C outlets that power my audio system) that controls a resessed light over my fireplace mantle. Any suggestions as to what else to try? Thanks much.

smrex13 Yes - I'm talking about halfway up the Marantz volume control when I mention "50" |
motoraway I'm grounding from the turntable to the Sutherland preamp/stage at present |
I've had quite a few different phono stages, and I don't think I've ever had a setup that didn't have noise around halfway up the volume dial. The high gain of a phono stage can do that. Do you listen at 50 or above on the volume? I never worry about it unless the buzz starts in my comfortable listening range. |
