I am using a Stanton 500.V3 cartridge with a Pfanstiehl 4820-D3 (3 mil.) stylus. Tracking 2 to 3.5 (I have tried 2, 3, and 3.5) grams on a Numark TT-2 turntable. On an occasional pre 1940 78RPM record I get distortion on male voices in the mid frequency range. I am curious if anybody has run into this, and if so what you have done to remedy it.
