Best tube preamplifier for under $15k

People whose ears I trust swear by the LTA. I have their UL amp and it is simply amazing so I would not be surprised if the LTA is right up there with the best. I recently bought the new Herron VTSP 360 ESP. Fantastic linestage--significantly better than the already great VTSP 3A (RO3) and should be on anyone's list at $6.5K. Both the LTA and Herron are less that half of the OP's price point but I would venture are right up there with others on the list that retail $15K but to be fair I haven't heard them because I can't afford $15K!

So what did the OP choose?

My first suggestion is MP-1 by Atma-Sphere or MP-3 fully loaded.
Second choice would be VAC
Third Choice: Lamm

BAT VK-33 ... 6922 based and you can tube roll to your heart's desire. Wonderful sound, built like a tank, reliable, and won't break the bank.

larryi brought up a very good point,that seemed to go totally ignored. I think there are too many unanswered prerequisites by the op. Otherwise it’s just everyone suggesting what they have. 

Perhaps an ‘One Careful Lady Driver’ ARC REF40 if one were to drop lucky
