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.

Forgot to add, I have the Aric Audio Special.


That Aric Special seems like a nice little preamp. Attention to detail, caps, adj gain feature too - nice. It’s great to see folks trying different preamps with the QS amps to get the best out of them. I’ve noticed quite a difference with the most subtle changes to preamps, preamp input tubes, cap changes, vintage input tubes in the amps themselves.

>> using different 6SN7s in the preamp other than re-issue TS 6SN7s...<< vintage RCA or Sylvania black plates, Sophia Electric Blues / TJ Full Music / Northern Electric. Was a game changer for my own QS amps.

Mesch,
Have you messed around yet with swapping out the vanilla stock re-issue TS 6SN7s that came with your Aric-Special preamp?

Decooney,thanks for the support on my purchase decision.  I have not tried tube rolling with this pre. I have owned it about a month. My approach is to live with it as is to enjoy and better understand what it is providing towards my listening experience. I am considering the purchase of a tube amplifier, stereo or monos, not sure. Considering Aric Audio or Quicksilver.

Hey, If you like the Aric preamp, maybe consider the Aric amp for the best synergy. I mix brands, and it goes well however IF you like the sound of your Aric gear and happy with the support, might be a good way to go.

Yes, I remain in communication with Aric regarding his amplifiers.
