We are now into 'spacetime'. Can Quantum Mechanics be far behind. In quantun mechanics, an amp can be good, bad, bright, dull, have a wide sound stage, narrow sound stage, low noise, high noise, even be in everyone's system, all at the same time!! That would mean everyone is correct, no matter what they say or when or where they say it. And just think, all this just to listen to someone like Ms Krall on an LP playing thru a tube amp!!!
Cheers
