If the grounding solution doesn't fix the problem, lower the gain from 60db to 45db (if you haven't already done so). Also, have you made any other changes to your system like speakers, cables, etc...? Its hard to troubleshoot without knowing the entire system.
Some noise issues with my new VPI Prime
Hi everyone,
Was fortunate enough to purchase a dealer demo VPI Prime. Have been enjoying it for the last week or so - it's a wonderful sounding table. However, I am having a couple of noise issues with it. It's still under warranty, but I was hoping to find a home cure if possible. There are two issues:
1) Motor noise. This is from the mechanical operation of the motor - it doesn't change with volume of the system, but it's audible during quiet passages. The motor makes a slight buzzing/rubbing noise with each rotation. I am guessing that some lubrication is all that is needed. I've tried setting the motor on a rubber pad, but that doesn't make any difference.
2) Buzzing from the tonearm wire. I get a buzzing that increases with the volume. By 50% on the volume dial it is quite pronounced (you can hear it from the next room). It is coming from the wire that runs from the tonearm to the Lemo connector on the junction box. If I touch the wire, the buzzing changes as I move the wire around. If I raise the tonearm very slightly off the unipivot spike, the noise becomes extremely loud. I tried to wrap some tinfoil around it, but that didn't make any difference. Could this be a defect?
Any thoughts on some simple fixes that might address these issues?
Thanks,
Scott
