CES 2011

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–Hz 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.

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.

Hi-Fi shows can be notorious for playing the same audiophile approved dreck over and over again. Not so in the VTL room. Luke and Bea Manley played one great tune after the next and introduced me to a bunch of albums I need to go get. Helping me enjoy this great music was VTL’s MB185 monoblock amplifiers ($14,500/pair). Using EL34 output tubes giving 185W in tetrode and 90W in triode, the MB185 offers a unique three-way setting that allows the user to dial in the amount of global negative feedback used in the amplifier. According to Luke Manley, this will allow users to fine-tune the sound of the MB185’s to best match the accompanying speakers and listeners’ tastes.

This system, the smaller of the two in the VTL room, was certainly to my taste. I preferred the MB185 in tetrode mode, finding that it offered the best balance between dynamic bass punch and smooth midrange and extended treble with the Avalon Indra speakers being used. VTL has always struck me as a serious company making serious products, but I had serious fun in their room at this year’s CES.

I have no idea what it has to do with an audio show either, not that Stephen Mejias seems to care.

AAudio Imports' Brian Ackerman holds what must the world's most expensive AC strip, the Weizhi PRS6. Priced at $3200, the PRS6 is machined from a block of Super Duralumin alloy and features a graphite grounding module. There are no isolating transformers or conditioning circuits, the PRS6 is purely passive. The thinking behind the product, said Brian, is "to get the noise out of the line without changing the sound."

Yes, the Weizhi is a gorgeous piece of audio jewelry but do people really pay $3200 for peace of mind? Brian told me that he is currently shipping 10 units a week, so I guess they do.
