Old Amps that can still Kick Butt


Not being a believer that time necessarily = progress, I would like to offer the following example of a sonic gem that has transcended time and can totally kick butt in a modern milieu:

The Robertson 4010. I got one of these about two years ago because it was in immaculate condition, the price was so low and I was inquisitive. I hooked it up and let it warm up for a couple of days. OMG this thing was in the super amp league: Transparency to die for, slam that you couldn‘t‘ believe for for a 50W amp.. Peter Moncrieffe wasn‘t wrong in his review of this amp: this thing is in the Sterreophile Class A component category hands down. Even after all these years.

What amps have you encountered that have defied time and can still kick butt today?

The parasound hca 3500 i have owned it for twenty five years and have never heard or found a better overall amplifier for all speakers. My favorite tube amp is the sonic frontiers for the same reason 

Hilarious. The Parasound HCA 2500 II and the Sonic Frontiers Power 2 were two of the worst sounding amps I have owned (around 30 in the last 30 years). To each his own.
