There is one advantage of repositioning equipment, even if only Temporary.
Such an investigation should cost very little monies and now the TT is set up, the only treatment for the TT following relocation, should be to re-level the Platter.
There is lots that can be learned about looking out for the needs of the styli, when used for the role in the groove to produce mechanical energy to be converted to a a very low voltage electrical current.
The Styli will receive ambient energies, of which certain types are able to adulterate the energy generated by the groove modulation.
As the methodologies for reducing transferred energies to the Styli improves, the end result is the perception of the end sound increasing in presenting as tidied up sound improves.
Platter Mats also fall in to the considerations for control measures.
