Preamp for atma sphere m60

The most logical choice would be an MP-3/MP-1 (haven't heard either yet). However, I'm using a BAT VK-3ixSE and it's a match made in heaven with my Atma S-30mk3.

Normally the preamp from Atma-Sphere, but I had excellent results with Klyne 7 Line or Lamm LL2. I think, these M-60 are easy to handle when the connected speaker is a match.

Ladies(just to be on the safe side) and Gentlemen I think that covers everybody, thanks for the responses.
Let's say I want to make this atma m60 work and really well that is, which preamp will be the last one for this combo. Something that will have future upgrade possibilities. I know the mp1 would be the best choice but I cannot layout that kinda dough. Therefore should I stick with mp3 and will there be enough room for upgradebility that will take it to the top, I know it shares the same topology. I know an mp1 from the earlier years may show up for decent money but the upgrades are costly.
I get a glimps of that wow factor with my system now with the sim pre/power, being spoiled a little I want to be wowed with tubes. I like the air and imaging you find in top systems. Can it be the audio horizons? Or will passive provide that too, or is the phono in atma sphere worth going there, I would like to think so. I am in favor of going with atma sphere, and am hoping the mp3 will suffice with all the tweaks. Comments?

I recently bought an Audio Electronic Supply AE3 on the recommendation of it being a giant killer with a friend's pair of tube monoblocks. Well, I shouldn't say giant killer as much as flat out sensational in his opinion.

I have the same pair of monoblocks as he does, and wanted to see what all the fuss was about. So, do I think the preamplifier is great in that combination? Well, it was pretty good, but I was left wanting for a lot more.

Then, I needed to put my M60 into the system for some evaluation, and holy cow, it's far and away the best preamplifier I've ever used with the M60s. More dynamic than I've ever heard, while adding a flesh and blood and romance that has never been there before. Previously, in my opinion, the other amplifiers had sounded better than my Atmas. Now, the Atmas have leapt over the other amps, and it's not even close. Not sure if the combination will line up with your tastes, but I sure found the end result to be truly outstanding.
