Balanced Power/Audio Magic Stealth Combination?

I currently use an Audio Magic Stealth in my system. I was wondering if the inclusion of a balanced power conditioner would further improve (or worsen) the sound? Would you install the device before or after the AM Stealth?

My Stealth improved when plugged into a passive Furutech ETP60 which is plugged into the wall via an Eichmann PC-more PrAT.
