AudioStream.com's Michael Lavorgna explains all the intricacies of computer audio.

VTL's Luke Manley was one of the many industry luminaries at the Coup de Foudre party.Through the control-room window of Graeme Humfrey's studio can be seen part of Graeme's large collection of classic pro-audio gear.

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.

Working alongside Steve Silberman of AudioQuest, Wavelength Audio’s Gordon Rankin offered a series of talks on computer audio for Mac users, while Jim Hillegass, the founder and CEO of JRiver Inc., offered corresponding seminars for users of Windows-based computers. My schedule allowed me to hear only a brief portion of Gordon Rankin’s Saturday seminar—and, regrettably, none of Jim Hillegass’s talks—yet even so, I learned things I’d never come close to knowing before. (An exemplary gem: When it comes to RFI rejection, Apple’s laptop computers are considerably better made than the company’s desktop models.)

In years past, the Montreal record shop Aux 33 Tours operated a generously sized retail booth at SSI, and I invariably helped them to lighten their vinyl load. I was disappointed that they weren't selling records at this year's show—until I noticed their display in the Hilton's hallway: All day Friday and Saturday, they offered a free shuttle service for people who wished to visit their store. (Sadly, the time was too short for me to take that ride.)

Here's the obligatory "People Buying Records" picture, and even though it was taken on Friday, which is usually the show's least-busy day, I had no trouble finding an opportunity to take a suitable picture. There were also quite a few people at the CD racks, but, overall, I'd say there were more LP buyers than CD buyers in evidence. Make of that what you will. (It may be a reflection of the fact that LPs are not as widely available.)

I think after every audio show I've attended there was some product that I realized too late I should have checked out—typically, when somebody later said to me "Did you hear the XXXX speakers? I thought they were great!"

After CES 2012, there was one product—actually, a line of products—that I had fully intended to seek out, but somehow this intention did not translate into action. It was on the plane returning home that I realized that I missed seeing the new wireless speakers from Dynaudio. I made a note to myself to make sure that one of the first rooms I'll visit at SSI 2012 would be Dynaudio's.

After having been at the show for some time, I received an email from John Marks, fellow Stereophile scribe, urging me—and Art Dudley, who got the same email—to try to listen to the Bricasti DAC that John Atkinson reviewed in February, which he said was adding five minimum-phase filters, as well as offering an optional asynchronous USB input. As it happened, I read the email just as I was walking by the Bricasti room, and I took this to be a sign that I should follow JM's recommendation.

Rethm, most of whose distinctive loudspeaker designs have been designed and built around full-range Lowther drivers, has now switched to a driver design of their own—which, like Rethm's loudspeakers themselves, are manufactured in India. The Rethm Maarga ($8750/pair) supplements a 6" version of that new driver with an isobaric pair of powered, 6.5" paper-cone woofers.

New at SSI was Rethm's first foray into amplifier design: a 16Wpc single-ended integrated amp called the Gaanam ($7750), built around the Russian 6C33C tube and featuring an outboard power supply, 6922-based preamp stage, and an all-transformer driver stage. Using a Lector CD player and Rethm's own all-silver speaker cable ($1250 for an 8' pair), the combination of Maarga speakers and Gaanam amp sounded spacious, clean, well textured, and very tactile, with fine bass extension and bass color; my impression was that the consistently large crowd of listeners in this room agreed.
