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?

I have a Robertson 4010 in my collection. I will have to get it out and hook it up in place of the Sumo Andromeda powering the DCM Time Windows (a formidable combination!).
For difficult speaker loads I have a Perreaux 2150B. 340/680/920 wpc @8/4/2 ohms! This amp is sonically competitive with any of today's four and five figure amps! Typically can be found for $900!
The James Bongiorno-designed Sumo Andromeda (200 wpc) is another great amp from the past! 
@coffee-jerk: I have the first production BEL 1001. Serial number 0001. Bought from the original owner who got it directly from Richard Brown.
