Hi Sharri...I've got a VK500 amp with Batpak hooked up with BMI Whales to a VansEvers Unlimiter. I use another Whale from the wall to the Unlimiter. The guys at BAT may be a little sceptical due to the amps sensitivity to power surges, lightning, etc. When I originally set up my amp with only the Whales plugged into the wall, I noticed the 5 amp fuses would blow during a thunderstorm. We get alot of thunderstorms here in Florida so unplugging them almost every day is a true pain. After alot of research and questioning fellow audiophiles, I decided to try an Unlimiter. I'm really glad I did. Not only did the bass get even deeper and more defined but the entire soundstage increased in all directions. PLUS...no more blown fuses! I'm not going to state that the Unlimiter will completely protect the amp but it really has been a great investment. The Whales are a true bargain at their price. They enhance the musics clarity and focus. They remove all background noise allowing you to hear all of the detail that your gear will reproduce. I have 6 of them in my system and give them my highest recommendation...
PC s and/or conditioners etc for BAT
Curious as to what BAT owners may be using if they are using power cords, conditioners, regenerators, etc. BAT is extrememly cautious and recommends nothing. But I know some people experiment. I have a VK-30SE, D5SE, and VK-60 and use a mix of BAT stock cords and Cardas.
