Rushton,
I did eventually have a Callisto Signature in my system for a few weeks. It is an incredible component. I'm using an Atma-Sphere MP-1 with my Atma-Sphere MA-2 amps right now. As expected there is great synergy between the two.
The MP-1 drives and controls (grips) my MBL 101Es better than any other preamp I've tried. I know it's odd to think of a preamp 'controlling' speakers but the difference between the MP-1 and other preamps in this regard (including the Blowtorch that I owned) is not subtle.
