It was no accident that residential architect Mark Cronander, aka Variac, scheduled the Sixth Burning Amp DIY Fest for October 28, on the same weekend that the AES Convention (Audio Engineering Society) took place in San Francisco. Not only did Cronander attract a fair number of new folks who came into town for the convention, but he also scored, as a speaker, class-D amplification expert Bruno Putzeys of Belgium's Hypex Electronics.

The largest US high-end audio show open to the public is also, despite its size and occasionally snow-encrusted environs, the warmest and friendliest audiophile show in the country. For this we owe thanks to Marjorie Baumert, who continues to nurture and sustain the show following the death of her show co-founder and husband, Al Stiefel, at the start of 2009; the exceptional staff at the comfortable Marriott; a dedicated cadre of volunteers drawn from the Colorado Audio Society and Marjorie's extended circle of friends and family; and exhibitors who, welcoming the relative peace and quiet of the location, approach the show as if reuniting with old friends.
