Best 3 tube preamps under $18000?


I will be pleased to know your opinion, about which can be the 3 best tube preamplifiers, with a price, NEW, under $18.000. I want to use them with SS amplifiers.

As the proud owner of a VAC Ren pre, I was flabergasted (astounded, amazed, etc) when I heard the Veloce LS1 battery powered tube preamp (about $14k or so). This is easily the single most dynamic, blackest background, most musical pre that I have ever heard in any system. Having taken one home for audition ( with the corresponding matching phono stage also battery powered), I am now in the process of trying to figure out how to pay for the one I have ordered.
If you only have one source and it is digital the an $18000 pre amp is a big waste of money. It is a very expensive way to turn the volume LESS DOWN. $18 grand could go along way to improve a system in other ways.
Having owned CAT, Joule, and Atma-sphere, I would say that 6550c's observation should be given some serious consideration; you at least need to try a Passive - in the right system, you may not need to spend $18,000 to have SOTA sound. Try a Bent Tap-x for $1,000-$2,500; it is worth comparing to anything mentioned here (not that it would be your first choice, but for some, yes).
