Hey Mikemarv, the Cain & Cain I-Bens being displayed at the VTV show are actually mine along with my Art Audio PX-25 amp. I think the dealer, Paul Lim of Imagine HiFi, will be using a single Bailey subwoofer(I use two). For preamplifier, he'll probably be using a Pass Labs X-2.5. I don't know the sources.
It will be interesting to see if it is possible to get halfway decent sound out of my speakers in a hotel room. And I've never tried a solid state preamp with the PX-25, so who knows how that will work.
BTW, I am a little nervous about lending out my speaks and amp - never done that before. But, people really need to see C&C's in person to appreciate the workmanship and quality. Hopefully, room acoustics will be friendly so it's possible to get a hint of their true potential.
