Preamp: Cary versus BAT

Can someone tell me how Cary preamps sound versus BAT? I do have a VK-200 which I like very much but not sure if a BAT preamp is the best match. By that I mean some people think BAT preamps are a little on the darker side or too warm. I have in mind from Cary, the SLP2002 or 308 and the BAT, the VK3i or 5i. I like a neutral or slightly to the warm side of neutral sound with nice detail and dynamics. Low level detail is a must.
