What are you powering your Martin Logans with????

I have a set of Prodigy's that are being powered by a Audio Research VT200. It sounds great, I recently upgraded from Sonic Frontiers Power 2. System sounds much cleaner, with a deeper soundstage, and just smooooth. I am wondering what other people's set-up's are and what they think of them.

Anyone using Wolcott mono's........... or other ARC gear????
