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?

Shindo (velvet sound, low power speakers, expensive) BAT (expensive and gobs of power) Line Magnetic Audio (great budget) Border Patrol (low power speakers, horns) and Decware (great reputation) and ARC (quality and name recognition) 
As far as build quality and attention to detail - Canary Audio is absolute top of the list.  Polk finally we agree on something :-)

Good Listening

I have I have been very fortunate with the tube amps I’ve owned over the years.  Jadis Defy 7 and JA 200’s, Atma-Sphere, Joule Electra, Convergent Audio Limited Edition monos, and now CAT JL-2.  All have been trouble free.  The JL-2 is about 150 pounds and built extremely well.
