Highest BUILD quality tube amps?


Not so much with sound...lots of ways to fine tune thru tube rolling, etc. I'm just curious which tube amps are built to last for many years with the least amount of repairs. I know Mcintosh comes to mind for longevity. I was snooping around on the web and Air Tight seems to be built like a tank and I've never read any poor repair histories. Luxman same thing. Any others come to mind?

@lukaske, do you mean the EAR 859? That is one of their tube power amps, the 868 one of their pre amps. Good products, good designer (Tim de Paravicini), good company.

Sbank- “Haven’t seen a similar thread where a category has so many enthusiast responses for so many brands. Is that telling us something about tube amps?”
Having heard SS amps, class d amps, class A and AB amps and some other hybrid ones, I prefer the sound of tubes. Viva la Vacuum! Long live tube amplifiers!
