Really nothing to contribute to the actual OP subject, but speaking to things working without explanation, my first encounter with a record platter weight reset my belief in logic in reference to this avocation.
The other one was selling retail solid billet cones placed under floor standing speakers (Snell) in 1983. Worked magically.... and nobody was stoned or drunk. The effects of stabilizing sound stage, tightening bass and focusing vocals was inarguable. And we sold a lot of those things. Precursor to Gaia and Townshend.
OP posting date duly noted. Just had some extra time on my hands.
