I don't own them, but I heard them at the 2004 RMAF and thought they were fabulous. In fact, I thought they were better than the Continuum 3s I heard later in the show.
It's probably safe to say that, to some degree, my preferring the Calypso and your not being "sucked in" were probably the product of speaker/room interaction. Even so, the Calypso is an excellent speaker IMO, capable of bass extension and definition exceeding that which one should reasonably expect from a relatively small speaker. I'm a dyed-in-the-wool SP Technology speaker fan, and yet the Calypso exhibited characteristics (seamless driver integration, superb bass performance, detailed yet very musical mids and highs) I've come to expect from my own speakers. Soundstage and imaging were excellent as well.
I don't recall what supporting equipment was used in Denver, but the sound was excellent. Perhaps some of what you heard (or didn't) could be the result of less than ideal component matching. Based on my experience, I suspect the Calypsos are fairly revealing of upstream components.
FWIW...
