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.

"Didnt someone recently post this question?"

I made some edits to it prior to it getting posted and the Agon system posted multiple copies rather than just the final version.

Oh well, special bonus for me I suppose.
If the A'gon monitors see this, this thread can be deleted. It got posted multiple times as I was editing it initially.

Thanks and cheers!
Mapman,I was just having a little fun! I was going to make some changes on my system(way overdue!) but think ill wait till some of the bugs get worked out.Ray
Mapman's first post specified Amplifiers.
This post is open to other tube equipment.
I vote for Doshi Preamps. And how about those tube driven ICs??
For what it's worth, I used an Audio Note M1 pre-amp and P2SE amp for 15 and 16 years respectively with absolutely no problems regarding reliability. I never had an issue with either one. I no longer have them, but the new owners haven't reported any problems with either one to me.
