Best 3 tube preamps under $18000?

Hello and thanks to all that have posted his opinions, in relation to the passive preamp , I used-owned the best Bent model and the excellent expensive audio consulting, is not the way for me, another way is to use the dCS as preamp, for me is posible if you don´t use very good preamps, but always that I compared this solution with a excellent preamp, I have seen that this is not the solution.
Surprise by the ausence of names as CJ, Kondo, Vacuum state and for so much presence of the ref5, I never heard it, but the ref3 , for me and sorry for the people who owned, owns or like this preamp, is a very good preamp, but not exceptional, because for me it don´t have the soul that you can hear with Kondo, Connoisseur(SS), perhaps in the appropiate system with FM, Soulution, Boulder, Sovereign..
Then surely I need to explain more what I´m looking for: one preamp that sounds as this that I think that are excellents preamps, but tube preamp and with a very good price, is this a chimera- pipe dream?
I have a small list of contenders, but surely they are so small brands, that is practically imposible to hear them:
New Aestethix top of the line
SAS
Dodd
Wavac
Doshi
Wyetech opal
Audiospace
Nat audio

Then I hope that one of you can say: this is a lot less expensive and as good as the more expensives ones

Yes, Kondo was on my mind also but I can`t recall one that fits 18K retail price. I`m sure that you can find a used one for 18K.

Thanks Pluto, did you heard Concert Fidelity? how it compares to the great ones?

hello Pubul57, I have heard the Joule electra LA150 MKII SE, it´s good but not exceptional, did you heard the Marianne Electra Memorial preamplifiers?

Unfortunately I haven`t had a luck to hear it myself. It just seems to me that many reputable reviewers and other people who have a significant experience with upper class gear are extremely enthusiastic about Concert Fidelity. It also seems that CF gear is not very tubey sounding in it`s classical meaning but is more targeted to open and realistic presentation. So if you are looking to add some some tube warmth and bloom it might not be your first choice.
I´m sure that some members here have had a luxury to hear it so their options will be most valuable.
