Surface noise


I seem to have noticeable "noise" in between tracks on vinyl, especially at louder volumes. Should I try adjusting VTF? The system is a Luxman PD-441 turntable, Denon DA-307 arm, Grado Gold cartridge. Everything is pretty well isolated from vibration on a sand filled stand which is on floor spikes and the Luxman is sitting on vibrapods. VTF is probably near 2 grams right now. Thanks for advice.

surface noise is caused by the following phenomena

1) incorrect VTA, so that the sylus makes incorrect angled contact with the groove
2) signal induction into a MM cartridge from a ferrous platter
3) stylus wear forming flat wear spots that interfere with tracking of recorded vibration in the audible range
4) incorrect stylus pressure (usually too low)
5) aging of rubber like materials in some types of stylus suspensions

In addition, incorrect antiskating can cause a channel imbalance of surface noise

The signal to noise ratio of a properly setup, functioning catridge is determined by
a) the catridge manufacturer design
b) the ability of the TT to prevent micro transient vibrations from interfering with accurate stylus vibration tracing; micro vibrations cause an averaging/reduction in dynamic range between softest and loudest passages on vinyl playback.
given the stylus age and gradual onset of symptoms a prudent person would replace their stylus at this point rather than continue down a path that could be damaging your LP's due to worn out stylus or hardening of the suspension damper. But who am I to say, I only did this for a living in the 80's
