A McCormack power amp and a Audible Illusions preamp are a excellent match. Depending on how much you want to spend, a smaller ARC power amp is also excellent. The Belles 150a Hotrod sounds really good. As for the AI preamp, a used L-1 is in the $700 range, M3a around $1200(with phono) or the L-2 at about $1700. I have personally used all of these combo's so I know of what I speak. Don't shortchange the electronics with these speakers.
