Atma-Sphere in CO?

I'm looking to listen to one of Ralph's amps.  I'm in Denver and have Coincident PREs and a pair of Coincident's wonderful 300b Frankenstein's if anyone's interested in doing a comparison.  Obviously the speakers won't travel, but I'd be willing to pack up the amps and do some driving.

Will probably catch AS at RMAF, but would also love to do a home based A/B comparison...
