Hawaii-based Emerald Physics—a company I hadn't heard of until RMAF 2012—demonstrated their own US-built loudspeakers and electronics with a Peachtree Audio novaPre preamp–D/A converter playing music files from a laptop computer. Emerald's CS2P open-baffle loudspeaker ($2990/pair) works as a dipole below 1000 Hz, with a 15" woofer and a horn-loaded 1" tweeter. The retail price of the system I heard, including the Peachtree unit; the Emerald Physics CS2P loudspeakers; Emerald's DSP2.4 active outboard crossover/EQ unit ($850); and the company's EPI100.2 100Wpc digital amplifier ($1600) was under $7000, not including computer and playback software. While far from perfect—the bass wasn't especially taut, and there was little in the way of the sorts of texture and tone I crave—the performance was clean, spacious, and satisfying.

Squeezed into a small hotel room were the towering G’bell Epoque loudspeakers ($70,000/pair), driven by Artemis MK II monoblock amplifiers ($120,000), Stahl-Tek’s Opus DAC ($40,000) and Opus CDT ($37,000), with connections courtesy of Purist Audio Design 25th Anniversary cabling. How all this would have played out in a larger room, I do not know, but here, both period instrument and modern violins sounded edgy on different recordings, and bass was out of control on a third recording of a Mahler symphony.

Robert Kelly of German Physiks strikes a pose worthy of a Kraftwerk album cover while showing off the company's newest loudspeaker, the Unlimited Mk.II ($13,500/pair). With the company's omnidirectional DDD driver handling everything above 200Hz, the Unlimited Mk.II had an unsurprisingly open and spacious sound, with the same sort of near holographic imaging I heard in the Nola room: very impressive.
