Still, even if considering electricity sensitive to vibration and agreeing it could be influenced by outside vibrations, it is hard to understand why all of those influences must have negative impact on the final perception of the sound. On the purity of the source signal is understandable, sort of, but on an individual’s preferences not so much. With some luck/practice, there is a chance one would prefer the final sound and that is what, it seems to me, michaelgreen is promoting.
An anechoic chamber is not the most pleasant place to be.
