IIRC there are theories that the vinyl deforms slightly under the mechanical pressure and heat generated by the stylus contact and restores after the stylus has passed.
Perhaps the liquid present cools the vinyl such that it does not spring back normally, perhaps leaving microridges which cause the noise in question.
What is the nature of the noise/distortion ?....white/pink noise or related to suspension compliance/cantilever mass.

Every thing that you need to know about wire and cable.
This is just part of a post on another forum:

Wire:

- Copper is always warm, which is a better trade-off vs bright and harsh so copper is safe and some prefer it because it is warm. But warmth masks detail, especially in interconnect cables. Different types of copper also have different degrees of warmth... The warmest cable will use lower purity copper in heavier gauges with PVC insulation, anything less than 23g will have an effect on the highs making the sound seem even warmer. PVC adds to the effect, more muddy than warm though. Upgrading to higher purity copper, using wire thinner than 23g will and using teflon insulation will all improve the performance of the cable by reducing warmth and increasing resolution. Litz-type copper wire is made of many runs of very thin copper wire that are individually insulated and arranged so there are no inner or outer wires in the bundle, accomplished by twisting and/or braiding the wires, sometimes around a round or flat former. UPOCC copper is also less warm and more resolving vs typical copper and is about 3% more conductive vs the standard ETP copper.

it gets better later on in that thread --
One thing rarely mentioned with power cables is that power is an AC signal, a 60 Hz sine wave, so simple resistance doesn't completely describe the impedance, like signal cables there are complex impedances from the interaction of the AC waveform with inductance and capacitance, so there is an AC impedance that takes L and C into account, but cable designers don't seem to notice. One of the benefits of aftermarket power cables is more instantaneous current available and looking at the power cable in terms of lowering AC impedance as well as DC resistance is helpful, so I use litz design in my power cables and it works incredibly well.

That reactance at 60Hz of the cable's inductance and capacitance must be really high! I'll have to calculate that some day.

One more thing I've never understood (and I do hear differences in playback between stock $3 power chords, and heavier gauge aftermarket or homemade powercords; I just haven't heard any across the board 100% for sure improvements, or detriments. I can't even be sure the subtle differences are due to time of day power usage, or how many loud noises I was exposed to at work : )) is the claim of higher current output from one's amplifier with (fill in name of supercord) plugged into it.
Would not the current limiting factor be the gauge of the power transformer windings?
The ones I've seen look a lot smaller than 14 gauge wall wiring.
