Amp craftmanship/Quality


I'm not so concerned how a  amp/line stage pre amp sounds. 
No not really, MY main concern is how ~~reliable~~ it is.
To me, all tube amps sound pretty close the same.
The most single factor of importance is ~~The Reliablilty Factor~~.
Repairs as you know are expensive, not to forget the suffering involved. = Pure hell. 
I own a  Jadis Defy 7, no repairs running 7k+ hrs,(20+ yr old amp)
Knock on wood.

I had a  Cayin CD17 tube player, 8 yrs useage, no repairs,.
This is what I am talking about.
I want a  amp that will  perform day in, day out, month after month  year after year, decade after decade, with no repairs.
Quality of build is everything in a  amp, Far less imporatance how it sounds. 
How it sounds is not a relaiable factor, as each of us has a  different set of hearing. 
I think most topics here are concerned about sound, and less about The Reliability Factor.

See, that's where you are so wrong. And nothing after that matters.......
Yup!! Even amp to amp some sound different.. Especially vintage stuff.

To me reliability is pretty much all the same. It is the sound that varies tremendously.   
I have a few different tube preamps and amps that I swap out from time to time....every combination of them has a unique but excellent sound.   

All have been reliable,  the quality of tubes dictates reliability in that gear
Generally speaking, gear that has been built in the last 20-30yrs is overall very robust. To place that criteria above sound quality is truly missing the boat.
