I would rate the Callistos much higher that the 3As. I had a home demo of 3As a couple of years ago and found that I preferred the considerably cheaper Athena AS-F2's. The 3AS sounded somewhat bright and forward to me.
I later took the advice of many Audiogon members and purchased a set of GMA Europas. They easily bettered the Athenas and I now have the Callistos which I am driving with a 12watt/channel Kr Audio amp. I still have the Athenas but only use them as home theater speakers.
