Callisto, not Calypso. I believe, like Io, the other Aesthetix preamp product, they are both moons of Jupiter.
I heard the Callisto, not the Callisto Signature, against the Hovland HP-100 pre. Although I don't think the Hovland is by any means a perfect product, I preferred the Hovland. The system was using a Levinson amp and Watt Puppy Sixes. The Hovland was more dynamic, sweeter and had more air and life in that system. I was really disapointed in the performance of the Callisto. Maybe it was just a bad match, but I found the differences stunning.
