sleepy, A couple things:
"
The laws of physics haven’t changed since the 80’s"
Agreed, however power cord, interconnect, speaker wire, & audiophile outlets have.
"
The insults from some members are probably a reflection of insecurity that stems from lack of understanding how power supplies and amplifiers really work"
Or (try to think outside of yourself for a minute)...
They are probably just tired of being told what they are actually hearing is not reality because another professor or engineer has been taught this by like minded professors or engineers that read all the facts required for audiophiles to understand from books that are really really old written by men who never heard recorded music at a level that even approaches the lower fringes of high fidelity.
