I got a Jolida tube integrated amplifier about 8 years ago after reading several good reviews. I've been satisfied with it and have had no problems. One of the things that finally convinced me to get it was the fact that there is no plastic on the unit; even the control knobs are metal. The remote control for the unit is also metal and weighs about a pound; the "buttons" on the remote are steel bearings about 1/8" diameter. I figured if they paid that much attention to such a small detail, I would trust them. No regrets.
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?
