SSI 2012

Retailer Coup de Foudre and Canadian distributor Tri-Cell built one of their exhibits around a pair of Joseph Audio Pulsar loudspeakers ($7000/pair, to be reviewed in the June Stereophile by Mikey Fremer), driven by the 70Wpc Brinkmann Audio Vollverstarker integrated amplifier (also $7000), with a MacBook Pro and a Wavelength Audio Brick D/A converter ($2200) as the digital source. As always, Jeff Joseph's room setup was difficult to fault, and the system was smooth, colorful, and dynamic: Listening to the Gypsy swing music of the Howard Fishman quartet, I was happier than I'd been all day.

California-based Constellation Audio, represented by the well-known engineer Peter Madnick, supplied the amplification for the Magico Q3 loudspeakers. On audition were their Virgo preamplifier ($19,000) and Centaur amplifier ($24,000), set up with elegant looking (and apparently effective) loudspeaker cables and interconnects from Argento Audio of Denmark. Source components were the C1 D/A converter and D1 disc transport from CH Precision of Switzerland.

One of the more controversial products at this year's SSI was the demo of "Axial Triphonic Speakers" by Lys Audio. According to company president Jacques Gérin-Lajois (given a running translation from French by one of his associates), this is based on a patent that was obtained 65 years ago, but has not been put into practice until now. As I understand it, it involves starting with a monophonic source, obtained by summing the stereo channels (or multiple channels), and then splitting the mono signal into bass, midrange, and treble, sending these to the appropriate speakers. Depending on the impedances, you can use just one amp to drive all three speakers, or (as was the case with the SSI demo), one amp for the midrange and treble, and another for the bass.
