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.

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.  
adapters will not improve the sound......You should choose BAT for best integration.
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.
