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.

I have great results with the Bob Carver 180's. They are outstanding performers.
Thanks for all the responses.

One thing I gotta ask is how much does looks/appearance factor into your tube gear buying decision?

Gotta admit that I love the distinctive industrial/laboratory/retro look of a lot of tube gear so the appearance is something that I think matters for me as much as all the rest. Meters that serve a useful purpose are also a plus for me in terms of aesthetics.
I LOVE meters...I often keep my Squeezebox Touch in its "meter mode" because it looks so cool. I think all amps should have glowing little needle meters...Pass does it...Cary, McIntosh, D'Agostino...I was looking at 2 new Rogers amps in a shop the other day...they look like 1956 Buicks...great stuff.
Another tube amp feature that is of interest to me is tube biasing. I am interested in doing this as simply but effectively as possible. Maybe a meter is part of the solution. Which amps fit the ease of biasing requirement best?

Thanks.
Mapman, you just described my Emotive Audio Vita amps. Tiger maple bases and a retro-looking meter for adjusting each tube's bias. See the photo on my system page.
