Who makes the highest quality tube amps?


One scale of 1-10, 10 being best designed and constructed technically, personal sound preferences aside, who are the 8s, 9s, and 10s?

VAC, ARC, Atmasphere would seem like likely candidates I can think of. Are they ?

Where does Decware rank? Rogue? How about others?

SOme technical facts to help support any claims is appreciated please.

Durability and reliability matters to me here as much as anything. I would want my tube gear to continue to work as reliably as designed years down the road as well as up front.

THanks.

Thanks.

@Zd542, Tube amp from Krell?"

Sorry, just kidding. It was just a little humour. For some reason, I couldn't help myself.
Von Gaylord Audio designs some awesome tube gear. I have the entire line and I am smitten.
In addition to some of the above mentioned, David Berning's designs since 1974, have a legendary status for both reliability and technical design and would have to be in the discussion. Example, I have owned the zh270 for 11 years and the outputs test at or very close to their rated transconductance value STILL and all the various input/driver tubes still test strong. Not even a hiccup from this amp, totally reliable and a strong case for those concerned with the reliability of tube amplifiers. McIntosh would also be a very strong candidate.
I agree with you tubegroover. A friend of mine still has an Audionics BA-150 designed by David Berning. It works and sounds great.
