BAT VK 3i vs Audible illusions mod3a ??

Hey. I'm still looking for a preamp. Since I just blew a bunch of money on a vt100mkii i'm looking for a full function preamp (line/phono) and was hoping some of you people could set me straight as to which is the better choice. (they seem to go for similar amounts in the used market). I've got Acoustat electrostatic speakers (model 3s), 777es, oracle delphi mkI if that helps. 70/30 for cd/lp
Thanks, can't wait for the responses!
