My other joint best sound at CES was to the On a Higher Note room at the Mirage Hotel across the street from the Venetian. On dem was the G2Giya ($50,000/pair), which made its debut at the 2010 CES, driven by a Luxman stereo amplifier, and the Audio Aero La Source tube preamp/digital player, hooked up with Shunyata's new Anaconda line of cables.

The G2 has half the cabinet volume of the similar-looking G1Giya that Wes Phillips reviewed last July, and replaces the larger speaker's twin 11" woofers with 9" units. Whether it was the smaller speakers not exciting the penthouse room's acoustics as much as had the G1Giya the previous year—the Mirage's glass-fronted rooms may give spectacular views of Las Vegas, but they also flap at low frequencies—or the new front-end and cables, but the sound on José Carreras singing the audiophile classic Misa Criolla, Peter Gabriel's idiosyncratic but convincing reading of Paul Simon's "The Boy in the Bubble," and the unexpected combination of John Lee Hooker dueting with Miles Davis, from the soundtrack to the movie Hot Spot was to die for, the system simply stepping out of the way of the music. As it should.

I heard a lot of good sound at the 2011 CES and T.H.E. Show. But my joint best sound must go to the room at the Venetian where Convergent Audio Technology was demming the new Ken Stevens Statement tube monoblocks with a CAT SL1 Legend preamp, Vandersteen 5A loudspeakers and MSB digital front-end, with cabling from Stealth and AC supplied by The Essence Reference system.

As I walked into the room on the final afternoon of the Show, a Chopin piano work was playing. yes, the recorded perspective was close, but my goodness, the instrument was there in the room! (It was the Gold Collector's Edition on First Impression Music of Jun Fukamachi at Steinway.) Effortless dynamics, palpable instrumental presence, tonality, musical power—you name it, this system did it.

Without a doubt, the four-way, five-driver Magico Q5 that Michael Fremer reviewed last November was one of my loudspeaker high points of 2010. But at $59,950/pair, the Q5 is definitely a speaker aimed at the deep-in-pocket. Magico's Alon Wolf proudly showed his new Q3 at CES, which, at $34,000/pair, is going to appeal to a somewhat wider market.

A three-way sealed-box with three 7" Nano-tec–cone woofers, the 47"-tall floor-standing Q3 uses the same proprietary beryllium-dome tweeter as the Q5 in the same type of space-frame enclosure, with a 6" Nano-tec midrange unit. The lower woofers roll off earlier than the upper one, to optimize the crossover to the midrange unit. Frequency response is specified as 20Hz–50kHz, sensitivity as 90dB (which is significantly higher than the Q5's 86dB), and impedance as 5 ohms.

I auditioned the Q3s in a system comprising Soulution pre- and power amps hooked up with MIT's new cables, and listening first to a Red Book file of Patricia Barber, then to a Jordi Savall/Hespèrion XXI recording of a baroque double-violin concerto, this was one of the best sounds I heard at CES, with excellent LF extension and definition, if a touch on the mellow side.

Magico were showing a prototype of the Q1 stand-mount in a back room, which they will be introducing at the 2011 Munich Show. This combines the beryllium-dome tweeter with a single Nano-tec midrange-woofer, but the price has yet to be decided upon.

The Devialet D-Premier directly converts the wall current to DC, then uses a high-efficiency switch-mode power supply running at a very high frequency to power the audio circuitry. I asked Matthias Moronvalle if this meant that the power transformer could be much smaller than usual? His response was to show me the two small wafers sitting on his laptop. "That's the transformer," he told me, "with a continuous rating of 600VA." Ulp!

I have been following with interest the goings-on at Nevada-based Wisdom Audio, since the company was revitalized with members of the team that had led Madrigal to success in the 1990s. But their concentration on in-wall speakers, using planar technology developed by David Graebener, means that they fall within the bailiwick of our sister publication Home Theater. Going in their room at CES, however, I was confronted by the LS4 floor-to-ceiling on-wall ($80,000/pair), which sounded magnificent driven by Classé's superb new CT-M600 monoblocks and reinforced below 80Hz by a pair of Wisdom enormous STS 2x15" subwoofers ($10,000 each; STS stands for "Steamer Trunk-sized Subwoofer"). The system controller, which includes an active crossover and room correction, costs $6500.

The LS4 uses four identical push-pull modules, each comprising a central HF section operating above 750Hz flanked by midrange sections covering the 80&#150Hz range. The backwave is absorbed within the enclosure, but the enormous radiating area still gives a sensitvity of 100dB/2.83V/m. (Impedance is 4 ohms.) Though the LS4 is fastened to the wall behind it, the weight is supported by a single spiked foot.

The LS4 is where architectural audio becomes aspirational audio.

Richard Vandersteen doesn't rush to release new loudspeakers, so given that the top-of-the-line Vandersteen 7 was a hot product at the 2010 CES, I wasn't expecting anything new at the 2011 Show. Talking to Richard in the company's Venetian suite, where they were featuring the Model 7, he casually mentioned that the new Tréo ($5990/pair) was at the Show, just not in his room. So I hustled me along to the Musical Surroundings room, where the Tréos were being demmed with a Clearaudio turntable and Aesthetix electronics.

Basically, the Tréo is similar to the $10k/pair Quatro Wood that Wes Phillips reviewed in December 2007, but replaces that speaker's active, equalized bass unit, with a conventional passive 6.5" woofer and an 8" flat-cone "acoustic coupler." Good sound at an equally good price.

Previewed by Michael Fremer in the October 2010 issue of Stereophile (pp.13–16), where he goes in depth into its technology, Sonus Faber's flagship loudspeaker, The Sonus Faber, will only be produced in a limited edition of 30 pairs. Apparently, all 30 pairs have been spoken for by distributors and dealers.

This is a big speaker—it stands 67" tall and weighs 672 lbs—and was being demmed in an appropriately large room with the large Audio Research Reference 610T tubed monoblocks. Or it would have been demmed, as on both my visits to the room, the electricity supply to the room had failed. (If you look closely, you can see the electrician's red toolbox to the left of my photo.)
