What speakers are you guys driving your BAT's with

Wilson Benesch ARC driven by a 75se. This amp can drive difficult speakers but i would stay with speakers with a fairly flat impedance curve not dipping below 4 ohms. The WB are nominal 6 ohms and I think overall a great speaker. All the WB for that matter.

VK-31se, VK-p5

AQ cables

REL B2

Shunyata PCs and Hydra

When I was using my VK75SE with difficult speakers (Wilson W3P2) I used Zeroimpedance.com Autoformers.

The BAT drives the speakers, not the other way around.......

I’m using Von Schweikert VR 5se and with plenty of head room, but I must admit the VR 5se listed at 94db.

Dunlavy SC4a using the VK60. Preamp is Placette Active Line Stage. The VK60 works extremely well with the Dunlavys - ample power and good bass in a medium size room.
