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.

Jdec,

Class D amps aren't going anywhere.

I've dabbled with adding an additional system built around
high efficiency speakers and a tube amp for awhile and hope
to do that someday.

My Triangle Titus speakers are tube friendly. I could use
them in my current second a/v system with a tube amp. I use
a mhdt Paradisea tube DAC and Tube Audio Design Hibachi 125
monoblocks there currently with an old NAD 7020 run as the
pre-amp.
