solid state power amps, golden oldies
What solid state power amps have stood the test of time? No older than 1980 and no newer than 1990. What amps, if introduced today, would still be given positive reviews? I believe that exceptional remains exceptional, regardless of time. Better older and exceptional than new and mediocre.
