Preamp for a BAT VK-55.


Have a VK-55 on the way soon and have a few pre-amps I'm considering.  
1. Primaluna Dialogue Premium
2. Audio Research LS-26 or LS-27
3. BAT but not sure which one. 

Phono isn't needed and no more than $3000 is my budget.  Any recommendations appreciated.

FYI I have a VK31SE on the way. From what I have read it is more musical and dynamic than the 32SE.  Also it is very close to BATs early 50 series which is out of my price range. 
Stingreen I didn't think the adapters would help the sound just wondering if they would hurt it?  One can become very confused after reading reviews and opinions on each BAT preamp (VK30-32 SE and non SE). The opinions are all over the place. 
adapters will not improve the sound......You should choose BAT for best integration.
I'm leaning towards a BAT pre-amp.  Used to have a VK5i a few years ago but the VK30 and up look to be more attractive and functional with the newish interface.
