Skeptoid: Digital vs Vinyl

[kraut]

Most of the heat is produced inside the groove walls by the pressure of the stylus deforming the vinyl, not the friction of the stylus against the walls. The presence of a cooling agent has little effect.

What does it matter where the heat is produced? If the groove wall gets deformed, the resultant heat will still be dissipated faster with a cooling agent present than without. And the cooling agent is in the groove after all. I do not understand your argument.

By your logic water surrounding a combustion motor cylinder will not help dissipate the heat because the heat is produced inside the cylinder?

For me, the evidence was that Discwasher found large quantities of acetic acid on the disc surface

Evidence by Discwasher is tainted, biased and therefore useless. Show me proper analysis of what is found with proper ph readings and I might be convinced. Other than that - hearsay.

including 85% polyvinyl chloride (PVC), 15% polyvinyl acetate (PVA), antistatic agents, dyes, stabilizers (heavy metals such as lead

I tried to find evidence concerning the composition of record grade vinyl, and could not find among the sources (several google pages) any that clearly defines what is included, even the one I linked to is fairly vague.
I looked into the chemistry of polymer vinyl acetate and some references were made to various products using this in conjunction with chlorinated form of vinyl polymer, but no clear indication of its use.
The author linked to fails to supply any sources, so I will not accept his statements just now. The same goes for Wikipedia, no sources linked to support that statement.


Jean Hiraga, 1978: having read statements concerning tube amps by Hiraga, I have some difficulty accepting him as a serious source.

The plasticiser dissolves the paint and welds the cable and paint surface together, peeling the paint when the cable is moved

I have no experiential references to your statement. I do not know what you are talking about.
The worst thing that I found regarding plasticizers is the deteriorating foam of old SLR cameras ( I collect pentax slrs, for use, not show) >40 years old.
