The trouble with audio shows—apart from the cheap call girls and the occasional gangland-style execution—is the fact that, even in nice hotels, the smallest rooms tend to sound like crap. So it was at the Hilton Bonaventure, where acoustical challenges plagued no exhibitor more than Audio Note. Their excellent AN-E loudspeaker—a pair of which I own and love—requires that both units in a stereo pair are sited close to their respective corners. That proved impossible at the Hilton, but Audio Note’s Dave Cope compensated brilliantly and made a fine sound nonetheless with a pair of AN-E Lexus Signatures in striking maple veneer ($15,200/pair), photographed here by JA and driven by the Jinro integrated amplifier that I reviewed in the March 2011 issue of Stereophile.

On Sunday at 2pm, John Atkinson gave an illustrated talk entitled "How to measure loudspeakers and what the measurements mean." The scheduling was not ideal, just three hours before the show's closing, and the door to the meeting room where the talk was held was locked, and could be opened only from the inside or with a special card, which was not provided. As a result, attendance at the talk was not as great as it might have been, but the people who were there listened with rapt attention. One person told me afterwards that he has a book on loudspeaker measurement that he's had difficulty understanding, but, having heard JA's presentation, it made much more sense to him. Other than the specifics of how loudspeakers are measured, I thought the most interesting part of JA's presentation was . . .

Master recordist Rene LaFlamme of Fidelio Records marked the release of his first LP—a remastering of Melanie Barney’s and the Buzz Brass Ensemble’s colorful recording of Holt’s The Planets—by adding to his demonstration system an interesting new turntable called the Kronos. Designed and manufactured in Montreal by Louis Desjardins and photographed here by JA, the Kronos is described as the first commercial turntable to use both a fully sprung suspension and a system of twin counter-rotating platters. (The perpetually fascinating 47 Laboratory 4724 Koma turntable, reviewed in Stereophile by Michael Fremer, pioneered the latter but lacked the former.)

This relatively modest-looking system in yet another Son-or-Filtronique room at SSI produced some superb sound. The Vienna Acoustics Mozart Grand Symphony Edition speakers ($3500/pair) were being driven by an Ayre AX-7e integrated amplifier ($3500), with the source an Ayre DX-5 universal player being used as a DAC for USB data fed from Amarra running on a MacBook Pro. The USB data connection was AudioQuest's inexpensive Carbon and one AC cable and the speaker cable was by Shunyata. There was also a single Nordost Odin AC cable. If you consider that the Ayre player was being used to provide the same functionality as a $2500 Ayre QB-9, it could be argued that this single AC cable cost as much as the rest of the system together. "It gives an improvement in sound quality and that's justification enough," answered Vienna's Kevin Wolff when I queried him about the system's price balance with the Nordost.

One of my favorite sounding rooms at SSI was the large suite featuring Verity Sarastro II speakers, the new Nagra 300B stereo amplifier that made its debut at the 2011 CES and a Nagra PLL preamp, with a Nagra CDP CD player and Nagra VI solid-state digital recorder being used for the front-end, all hooked up with Nordost Valhalla cables. The sound of a Jordi Savall ensemble performance of Vivaldi Oboe Concerto, played back on the Nagra VI with 24/48 resolution, was lifelike and easy on the ear, but without sounding either mellow or laidback. perhaps the sound was a little congested on the climaxes with larger-scale music, but this was one of the bigger rooms at the Hilton Bonaventure and the amplifier is limited to 20Wpc.

I had to make several attempts to visit the Son-or-Filtronique room featuring Sonus Faber's new Amati Futura speakers ($34,000/pair), but the line of would-be listeners patiently waiting outside the room was daunting. The Futuras were launched at last January's CES but not being demmed; at SSI, they were being driven by a Boulder 2060 amplifier, with a dCS Scarlatti and Boulder 1021 used as digital sources.

The impressive sound of the Focal Maestro Utopia III speakers in one of the SSI rooms being run by retailer Son-or-Filtronique was familiar from my July 2010 review but the small amplifier driving them via Crystal speaker cables was not. It was the Micromega AS-400 integrated amplifier ($4995), which Art Dudley will be reviewing in the July 2011 issue Stereophile. As well as the usual analog inputs, the AS-400 accepts WiFi audio data via a new version of the French company's Airstream module and uses a high-quality D/A section using Cirrus Logic DAC chips.
