As stated on prior occasions: Cart’s are fragile. which exposes them to deterioration from both exposure to an environment and from typical usage.
Either types of deterioration are unavoidable, where the only measures to minimise the loss of optimisation, would be to use the Cart’ frugally and Vacuum Chamber store with no UV exposure.
The Heyday of Vinyl has Co habited with endless research from qualified research entities, to make known what damages a Vinyl LP and accelerates Cart’/Styli wear.
Pretty much correct geometries, force and clean source material is plenty enough to keep all in fine fettle.
Recently I have shared a report which strongly suggests Ortofon have Damper materials in use that are showing they have properties that are with longevity in maintaining fit for purpose.
Another report from myself, where the source is a very experienced individual in Cart’ refurb, flags up a issue with a Brands currently available Cart’s that are claimed to have a Damper material that deteriorates very speedily, to the point the Cantilever interface is far from how the factory interface was produced.
New Cart’s with a large price tag, deteriorating at a speedy rate, would be sensible to avoid.
Olden Cart’s even if NOS Olden are exposed to deterioration!
The user of such a Cart’ has options on how they are to proceed with using it. I am an advocate of Cart’ refurbishment, and strongly suggest that a more than satisfactory outcome is able to be the end result.
Is the OP leaning towards Damper replacement is something to be prioritised, when having a particular Cart’ type in use?
