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?

So many great amps listed in this thread.  I’m about to move overseas in just under a month so now I’m on this shoe box sided British integrated amp phase and have had an Onix OA21s & OA 20/2 which were both excellent mid 80’s amps.

Now I have an original Linn Majik I and a Meridian 551 and both are quite good.
