In regard to moving coil cartridges, I would say:

1. This may simply be a symptom of electricity variability.  I would listen for a few days and see if it improves.

2. Cartridges not used for a while need to loosen up a bit in regard to the suspension.  Again, it may improve with continued listening.

3.  Aging suspensions may need mass loading adjusted to compensate for this natural aging process which changes how the cartridge responds to the set-up.  The set-up may not have changed, but the cartridge HAS physically changed and the setup needs to be adjusted to compensate for the new physical characteristics.  Mass loading reduction is usually where I start.

4. As a last resort for a moving coil, consider degaussing it.  It is a 2-edged sword, as it can bring a tired, dull cartridge back to life, but requires subsequent maintenance treatments.

Adrian
