So far we've been told that the holy grail in turntable platters is
either glass or plexiglass. These are very different materials. The
fact that the parameters of a 100 year old technology can't be nailed
down any better then this is indicative of how much ******** rules the
world of vinyl playback engineering.
A disc with a pickup resting on it acts rather like the diaphragm of a
microphone. Anyone who ever had a Transcriptors's design will be well
aware of this.;-)
So it seems only common sense to me that the disc must be isolated from
vibration of any sort - either structure or air borne. Including those
from the speakers. This must involve some form of heavy cover to the
entire turntable assembly.
