Best tube preamp for Quicksilver V4 tube mono's (newest KT150 version)


Just purchased a pair of Quicksilver V4 mono tube amps, the newest KT150 version.  Will be arriving this coming Wednesday.

http://quicksilveraudio.com/products/v4/

Single ended
Input impedance is 100 K ohms
Input sensitivity is 1.5 volts

Now need to purchase a nice preamp.  Would like to get the most 'bang for buck' by getting a very nice condition used pre-amp.

On my radar so far is:

EAR 868
Audible Illusions M3b or L3a
Herron VTSP-360

I have had 2 different AI M3a pre-amps in the past, so I am very familiar with Audible Illusions 'sound'... not sure what is the differences between the AI M3b and AI L3a, besides the M3b having  phono stage options and the L3a remote controlled volume?

No experience with Herron or EAR, but from what I have read EAR, if compatible, may be the best performing?

Suggestions greatly appreciated. 

Also would like to hear from other V4 owners.

Greetings, When I began Audio Connection, years ago a Julliard trained wise owl musician strongly suggested whatever I do, make sure to continue a strong positive relationship with Quicksilver Audio and Vandersteen. After many years this still holds true bearing witness to their extraordinary performance and issue-free operation.As witnessed by their steadfastly loyal customers including the many who have come full circle. Success fuels success! JohnnyR Audio connection
"Wise owl"for sure.  

Something to be said about buying nice new proven products at reasonable prices and skipping the whole used > shipping > repair/upgrade cycle. Sure saves a lot of time and headaches, and the "quality costs less" theory applies for the long-term.  

I’m one of those who came "full circle", or at least recognizing true value, with an appreciation for clean and simple designs both offer. It seems there are many loyal folks who buy Quicksilver/Vandersteen or Quicksilver/Klipsch combos. Always see lots of praise for both and less rotation of gear with them.

Perhaps there is nothing else for them to wonder about, it just "works" out of the box as-is, and they get to spend their time simply listening to music. :) Time savings is a true value $ too.

I am going to give Johnny a hard time here, because he is not really the founder of AC. I know that because I bought a Denon DP80 at AC  (on an early VPI HW9 two-arm base) from Hart, the guy who did. Of course, Johnny has taken the place to another level.

I'm sure Johnny will be ok with me clarifying AC's historical record.
Get out..Audio Connection without Johnny R is like the Starship Enterprise without Captain Kirk. Cheers Johnny -Don
