I corresponded briefly a while back with Gary Koh, CEO of Genesis. Gary has owned the company for the past five years, and moved it from its original home in Colorado to Seattle, Washington. When he took over the company, he was aware that his background was in computer software, not electronics. He decided that this could be an advantage. "Not being an engineer, I didn't know what was impossible. This explains to some degree the types of projects I've decided to take on, and those that have been achieved."

The Heisenberg—Audionet's largest and most powerful monoblock amplifier—was on display in a portion of the suite shared with YG Acoustics…

Harman International’s High-Performance Group’s exhibit featured a live demonstration of its most expensive equipment, including two Revel Rhythm 2 18" subwoofers ($10,000 each); two Revel Ultima2 Salons ($22,000/pair); a Macintosh MacBook Pro running Amarra software driving a Mark Levinson No.502 Sound Processor; a No.52 preamplifier ($30,000); two No.53 Reference monoblock amplifiers ($25,000 each); and Transparent power conditioners for the digital equipment and for the amplifiers. The rack also included a No.512 SACD player. The Revel Ultima2 Salons were crossed over to the subs at 80Hz with 4th-order slopes for both high-pass and low-pass filters. Listening to Diana Krall singing "I Used to Love You," I was struck by how all the loudspeakers and electronics disappeared leaving a holographic image of her voice, with a wide and deep soundstage.

The Pathos InPower monoblock amplifier ($13,500/pair) is a hybrid design offering 80W (at 0.4% THD, 5Hz–60kHz, ±3dB. It features some of the most beautiful industrial design I saw at the show. Designer Gianni Borinato describes it as a balanced, double INPOL power amplifier, with a zero-feedback, hand-matched. MOSFET output stage biased to run in class-A. The point-to-point wiring uses silver wire. Two triode tubes in the input stage are wired in opposite phase to form a double triode that is claimed to minimize distortion. The design proved its merit by driving the Focal 1037 Be loudspeakers with speed, dynamics, and excellent imaging. The room was a favorite among the Stereophile writers at the Show.
