Who makes the highest quality tube gear?


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.

Having owned a few, Viva, CJ, I think Ayon is hard to beat for price, sound and reliabilty, at the moment. No complaint about CJ and Viva, by the way.
I would give 10/10 to only two (both Japanese) companies, Air Tight and Kondo/Audio Note Japan. High praise indeed.

Atma Sphere, Jadis, and VAC merit the 8/10 and 9/10 in my book. Still, a lofty lot. I might include BAT as well, but I might not.

Take a step or two down from there for the likes of ARC, Ayon, Cary, CJ, Manley, VTL, with Quicksilver and Rogue slotting behind them.
