Audio Physic Virgo- What Power do you use?

I got into this hi-fi thing after hearing a set Audio Physic Virgo's for the first time. I love the sound. However, I think I'm short on ultimate performance due to my current gear. I'm using a Marsh P2000T and AS400 for power. Although the Marsh gear is quality stuff, I'm ready to move up. Any Virgo users out there? What are you using?
