Visitors are invited to share their personal listening setup, try out all kinds of equipment or just come to chat with people passionate about headphones.
2015 Capital Audiofest will also feature several special events including a lecture by Bill Hutchins of LKV Research (Friday 2:30pm) about “Preamp Design: Why I choose to design with discrete components and don’t use op amps or loop feedback.” Mattew Barton from the National Archives (Saturday at 11:00am and 2:30pm) will be presenting “Recorded Sound at the Library of Congress: A Backstage Tour of the World’s Largest Recording Collection”, discussing sound formats and demonstrating just how good old recordings can actually sound.

DCAudioDIY, the DC Area Audio DIYer’s Community will be in room 412 with several interesting projects and a very special debut of a unique amplifier, designed and built by David Berning and Tom Perazella, using the very special Yamaha 2SK77 VFET transistor in place of a tube. The amplifier uses chokes to provide the constant current necessary for high performance class A operation, resulting in far higher efficiency than standard constant current sources. To maintain the retro theme, the power supply is a choke loaded transformer isolated passive supply. As a nod to current technology gain stage power supplies use discrete solid state regulators.
