BAT Preamps, why such polarized opposite opinions?

I've never heard a BAT preamp. But I've heard enough about them on this and other sites. What is it about their sonics that people either tend to really like or really dislike them?

I've heard criticisms that they lack air, treble openness, life. I've been told the VK32SE is too dark, too weighted to the bottom, no air or delicacy on top.

I've heard these polarized opinions from audio salesmen as well, some who carried (carry) BAT. Let's just say I made alot of long distance calls to get a broad opinion.

But others love their sound and think they are fabulous.

I know what you're going to tell me - go listen to them yourself. Well, I live rural and it isn't easy to do.

So, instead, I'd like to get opinions across the spectrum from the Audiogon guys.

I'm using a Audio Research 100.2 with Dali Helicon 400's. I've tried Rogue, ARC, Sonic Frontiers, but haven't found the right preamp yet.
