Who makes the highest quality tube amps?

I currently own the Bob Carver Raven 350 amps. They replaced a Atma-Sphere M-60 Mk3.3 and before that Pass Labs X350 amps.

The newest Carver amps are really quite special. They are all made by hand, hard wired and made one at a time per order.

Does that mean that your's haven't caught on fire yet?

How the "F" do you measure "highest quality"? By the quality of the parts? By the quality of the assembly? Performance? Durability? How about versatility with different types of loudspeakers? How about the longevity of the manufacturer and customer service? These all make sense, but then what about these qualities relative to price? Or is price not a factor? What if I asked you "who makes the highest quality sedans?" Or, "who makes the highest quality watches?". I truly hate to be negative, but your question is simply stupid. You might as well ask "who makes the best sounding tube amps that are also durable"? And guess what? Even with that more narrow question, all you would get here is a list of names of what people on this Board own. 'Cause that's the way this Board works. Now I don't mean to be a complete ass, so I would express the opinion that for most tube amps, the quality of the transformers is incredibly important but so is everything else. Point to point wiring is nice too, but not always practical. You got some very good names. You can't go wrong with Manley, VTL, Atma-Sphere, Coincident, C-J, Quicksilver, and for the most part (smiley-they have had a dud or two), ARC. The big names got to be big names for a reason. You have to live with your choice so rather than take a poll of worthless opinions, take a look at the aesthetics and listen. I happen to think that more-so than with SS, tube amps often have distinctive appearances. I don't care how good they sound, I don't care for the looks of Quicksilver (those hose clamps holding down large capacitors just make me itch) or Coincident. A tube amp sticks out like a sore thumb (perhaps a poor choice of words) in any listening room, so pick out one that not only floats your aural boat, but that you also don't mind looking at. That's just my opinion. When Pathos first came out with their amps and when Manley first came out with the Stingray, I was smitten, but I am glad I never bought either. Sound has to come first. I am not saying they sound bad, but I believe there are better sounding tube amps out there that those two. 

Lets go with highest quality being equated to longevity.  Without any way of providing proof, I have to think that the Dynaco ST-70's have the most longest lived tube amps still in circulation.  I still think they sound passable.

Lets go with highest quality being equated to longevity.

Any Dyna made in the old days will need refurbishment to sound right and be reliable; otherwise the power transformer is at risk. Dynaco went out of business in 1978; I bought one of their last kits and assembled it for a friend who still has it. Its had its filter caps replaced a couple of times since then.

Or are you not talking about reliability?
