LATEST ADDITIONS

Nordost's Lars Kristensen can always be relied on to give an enthusiastic and instructive demonstration, and so it was at SSI 2010. I missed the first part of the demo, but I was there for what I was most interested in: the effects of the Quantum Qx2 ($1700) and Qx4 ($2700) Resonant Technology "power purifier" devices that Art Dudley has <A HREF="http://www.stereophile.com/artdudleylistening/listening_85/">written about</A>. I can't say that I really understand the technical explanation of how these devices work, but the demonstration showed that they certainly <I>do</I> work, the sound&#151;which without the Quantum devices was actually better-than-average&#151;acquired greater dynamic freedom, sharper imaging, and the soundstage became more spacious.

Audio show exhibitors have a lot of obstacles to contend with: equipment not showing up or showing up damaged, problem with room acoustics, problems with the electrical supply, equipment malfunctioning just as the show starts, and countless others. Ian Grant of Grant Fidelity told me that when he first set up his turntable front end it was picking up the signal from a local radio station! Being an ingenious engineering-type, he located the source of the interference (he could see the station's antenna from the hotel window), and got some building insulation material that had aluminum foil as part of its construction, and taped it to the hotel window. Voil&#224;! Problem solved!

In addition to ingenuity in dealing with setup problems, Grant Audio had another claim to show exhibitor fame: their sign said "Nothing Over $2500," In fact, most of their products&#151;some designed by Ian Grant in Canada but made in China, and others of Chinese design as well as manufacture&#151;were well under $2500. One of the more expensive items was the W30GT: tube-based integrated amplifier designed by Ian Grant that includes a phono stage and a DAC. It's $1950.

Simaudio's products were featured in several rooms at SSI and on Saturday afternoon, the Montreal-based manufacturer celebrated its 30th anniversary by sponsoring a concert by Anne Bisson, a local and apparently very popular singer/pianist, to judge by the packed house.

Place Bonaventure is located about halfway between St. Catherine street (which I think of as the center of downtown) and Old Montreal, near the river. As such, it's nearly in the shadow of St. Patrick's Basilica. I went for a walk Friday morning before the show started, but my walk was not as long as I had planned: the temperature had taken a big dive overnight, and so it was very...shall we say...bracing. But at least it didn't snow, as in previous SSIs.

As last year, Totem Acoustics had by far the show's most aesthetically sophisticated exhibit: a trippy mix of shapes and textures both organic and industrial, in which lights, flowers, textiles, and scents shared senses with the sound. The latter, also in typical Totem form, was exceptionally involving&#151;especially the Beatles' "Within You, Without You," Insane Clown Posse's "Ain't Yo Bidness," and "lua" by Dudu (no relation) Salinas. At SSI Totem also introduced a product that's still in concept stage, called Totem Skin: a removable sock-style cover that transformed cabinetry into art&#151;literally. Among the company's goals for this show, according to the Totem rep with whom I spoke, was to gauge consumer response to the Skins, and the reaction so far is positive.

The arrangement of Totem's new Tribe 5 wall-mounted speaker in on of their rooms at SSI raised my eyebrows. I asked Totem's main man Vince Bruzzese what gives? "We must reach out to non-audiophiles!" he said, adding that this was one of the impetuses behind the launch of the "skins" that Art Dudley wrote about above. "By arranging these speakers in an unconventional manner but showing that they can still play music, we reduce the fear non-audiophiles have." (My apologies if my paraphrase didn't capture the passion with which Vince spoke.) But the Trentemoller track I listened to, played on Chord CD transport, DAC, and amplifier, didn't sound any the worse for the unusual speaker setup.
