Years ago I had a Shure V15VxMR that came out of the box with a wonky stylus. I had to do some whining, but it got replaced. I still have the V15VxMR and it's still alive and making music. Sometimes stupid stuff just slips past QC. The bad one rode at a slight angle and did not give equal volume from each channel within spec.
Easiest way to get your way it to find the MFG specs and find out if it's within spec. Not within spec and still in warranty, REPLACED BY MFG.
