@ Chayro- He didn't say, "similar." He said,
"NO one has EVER HEARD a difference...." and yet,
even he heard differences in solid state amps, and made
recommendations based on such, quite often. And then; Dave's
post contains one of his quotes, "all amplifiers having high
input impedance, low output impedance, flat frequency
response, low distortion, and low noise floor sound exactly
the same." Regarding wire: all someone needs is Rat Shack?
"Tubes are for boobs?" Like I said, "utterly
disregardable."
