Michael Fremer and I got up early Friday morning and headed to the Mirage hotel where Devialet, a new French audio company, and its new North American distributor, Audio Plus Services, hosted a breakfast gathering to unveil their new D-Premier ($15,995). Encased in a mirror-finished solid aluminum chassis, the D-Premier is an all-in-one DAC, streamer, preamp, power amp, and phono stage. Not only does the D-Premier combine all these features in one product, but it also has a new and novel amplifier section; a patented Analog Digital Hybrid.

The input signal goes directly to a class-A amplifier. Though the output of this connected to the speaker terminals, it can’t deliver enough current to do so without help. The necessary high current is sourced from a class-D amp. The analogy of this amplifier is like power steering on a car where the driver is assisted by a powerful engine to turn the wheels; the driver turns the wheel but the power steering does the heavy lifting. In the same way, the class-A section of the amplifier controls the class-D section. The idea is that the amp retains the sonics of class-A yet maintains 85% efficiency in a 240Wpc amp.

The Devialet design team— Pierre-Emmanuel Calmel and Matthias Moronvalle (the latter shown in JA’s photo holding a demonstration version of the amp housed in acrylic)—was insistent during the presentation the D-Premier is not a class-D amp.

The sound with Focal speakers was clear, balanced, open, and grain-free, with no hint of the hash sometimes associated with class-D amplification. (The eggs at the breakfast were also excellent.)

A sister company of Argento Audio of Denmark, Organic Audio now launched a complete line of copper cables. These include Organic Audio interconnects ($995/1m pair RCA, $1075/1m pair XLR), speaker cable ($1950/2m pair), and power cords ($995/2m). By contrast, interconnects in the all-silver Argento range from $2000–$9500/1m pair. All products are distributed by Ricardo Reyes (left) of Musical Artisans in Skokie, IL.

Ulrik Madsen (right), who designs the cables and owns the company, was on hand to discuss his products. All Organic Audio cables are derived from Argento Audio’s entry-level Argento Serenity. “I wanted to take advantage of the connectors I developed for Argento,” Madsen explain. “We make all our Organic Audio connectors ourselves from the same metal as the conductors in the cables, which is OFC 99.997% copper. (The more expensive Argento cabling uses silver). There are no solder points; all attachments are made by applying set-screws to accomplish compression.

The last time I attended CES was three years ago. Although many things have stayed the same, there were also interesting changes—some of them profound. At the Las Vegas Convention Center, it seemed that almost every exhibit had to do with 3D, iPods, or tablet computers. At the Venetian, in addition to the traditional areas of speakers and amplification, it was music servers and related products—ably summarized by Jon Iverson in his wrap-up. Cables were big. (More on this anon.)

It was a very crowded show. At the convention center, the scene was at times like being on a subway platform during rush hour. At the Venetian, home of high performance audio, there were long lineups for the elevators—see photo. Although officially CES is not open to the general public, there were a lot of attendees with “Industry Affiliate” badges, and being an industry affiliate was apparently very broadly defined. This had the effect of increasing attendance, which I guess is not a bad thing, but it also meant that some of these attendees were really consumers, not industry people. One veteran speaker designer told me that some of the questions he was asked at this year’s CES were quite naïve, like “What if you played all these speakers at the same time?” He attributed this to these attendees being consumers (and not very knowledgeable ones at that).

My show report assignment was low-to-moderately-priced speakers, and I was very pleased to get this assignment, leaving John Atkinson to report on expensive speakers. As I said in one of my reviews, I’m more of a Volkswagen/Honda/Toyota than a Ferrari/Lamborghini/Aston Martin kind of guy. But CES had lots for the Ferrari/Lamborghini/Aston Martin crowd, and sometimes I was taken aback by the prices. In one case, I saw a three-way not-too-huge floorstanding speaker that I thought might be under the $10k that for me defined the top of the moderately-price range. I asked how much it cost. The answer: ninety thousand. I wasn’t sure I heard correctly. Nine thousand? No, ninety thousand. OK, this one is for JA.

One thing I thought was interesting was. . .

My most emotional moment at the 2011 CES came in the Harman suite on the Venetian’s 35th floor. I finally got to meet Kevin Voecks, Revel Loudspeakers’ head honcho, and he is every bit the gentleman people told me he would be. Playing in one room of the Harman suite was a system comprised of Mark Levinson digital and amplification gear including the new No. 53 monoblock amplifiers ($25,000 each) and the Revel Ultima Salon2 loudspeakers. The No.53 is Levinson’s first digital switching amplifier. One of the inherent problems of a switching amp is that it creates dead bands in the audio signal when the output devices cross over from a positive voltage to a negative one. Levinson says they have eliminated this problem through a patented technology that allows both sets of output devices to be on simultaneously for short periods of time. This is designed to be done without damaging the output devices or reducing their life expectancy.

After listening to a bit of the sample CD they had playing in the room, I thought I would play the opening cut, Eric Whitacre’s “Lux Aurumque,” from the CD While You Are Alive, which I had produced with John Atkinson engineering. It was the best I had ever heard it. I sat there listening to this recording, into which I poured my soul, next to Kevin, who headed the speaker’s design team, that delivered my vision back to me in a way I’d not realized was possible. I felt so lucky and thankful that I live in a world where designers like Kevin, and so many others who show their heart’s labors at CES, can help artists connect to listeners and listeners connect to artists. All I could do was thank Kevin and give him a copy of the CD, as he clearly enjoyed listening to it almost as much as I did. I only wish I could have played him the high-resolution master files.

I told Kevin that JA and I mixed While You Are Alive on a pair of Revel Salon2s while John had the speakers in-house for review. Kevin looked at me with a smile and told me that I was listening to the very speakers John had in his house. Life is magic sometimes.

The No. 53’s were clearly doing a great job, outperforming JA’s Mark Levinson No.33Hes we had used during the mixing. I gotta stop dissing the digital amps.

I first encountered the glass-enclosured Force dipole loudspeaker from Perfect Eight, which combines a full-length ribbon with 8 cone midrange units and a subwoofer handling the load below 60Hz, at the 2008 CES. Their 2011 dem, with the speakers driven by Ypsilon amplification, was noteworthy for having invited Ray Kimber to talk about and play some of his IsoMike recordings. (Ray is seen here on the left in my admittedly rather grainy photo—it was dark—with Perfect Eight's Jons Rantila.) I listened first to soloists from the Academy of St. Martin-in-the Fields performing a movement from the Mendelssohn Octet, then to a Mozart piano sonata movement by Robert Silverman (the latter one of my "Records to Die For" in the February 2011 issue). Despite my skepticism about glass as an enclosure material, the sound was natural and uncolored.

Hiding in the back room of their palatial suite in the Mirage, Musical Fidelity was running a demo of their M1CL:C Universal Music Controller which is now being finalized. MF says they are shooting for somewhere under $2,000 for the product which operates as a DAC and preamp and includes USB, SPDIF and analog inputs. I noted a USB input on the front and a beautiful color display as well.

Austrian Vienna Acoustics set up its own distribution company in the US in 2010 and when I popped my head in the door of their suite at the Venetian, I saw they were demming the Kiss speaker ($16,000/pair) reviewed a year back by Wes Phillips. (The rest of the system comprised Ayre KX-R preamp, MX-R monoblocks, and DX-5 "universal audio engine, with Transparent cabling.)

The Kiss looks like a stand-mount but it is really a floorstander with an integral stand. The sound in this room really flattered piano, whether it was a 24/96 file of a jazz trio featuring a Fazioli instrument, or Glenn Gould's 1981 reading of the Bach Goldberg Variations, remastered from the analog backup tapes.

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.)

Utah-based Zu Audio does indeed goes its own way, with retro, almost-full-range pulp-cone drive-units used in high-sensitivity designs. (See Art Dudley's review of the $4000/pair Essence in the October 2009 Stereophile. All of Zu's speakers have been moderately priced, so I was not expecting to see and hear a design costing $40,000/pair when I went into the Zu room at T.H.E. Show.

The Dominance uses three 10" paper-cone drivers, each with a whizzer cone, to cover the range from 27Hz to 12kHz. Each is in its own sub-enclosure featuring Zu's proprietary ZuRG loading (See AD's review) with the outer two tuned identically and the central drive-unit adjusted to give a bit more upper-midrange energy. There is also a downward-firing 15" subwoofer, covering the octave below 27Hz, and completing the line-up are two horn-loaded ring-radiator tweeters operating above 12kHz. Unusually, these are placed at the top and bottom of the Dominance.

For the dem, the subwoofer was powered by a Pass Labs XA30.5 but the main drive-units were driven by a 1.5Wpc Yamamoto SET amp. Yup, just 1.5W, but the Dominances still managed to fill the room with sound. Lows were tight and extended; imaging was tangible; jump factor was startling; but I couldn't get away from a touch of character in the mid-treble imparted by those whizzer cones.

"$175,000/pair?" I gulped. I know my beat at the 2011 CES was expensive loudspeakers, but the price of the Trenner & Friedl Duke took my breath away. Yes, the sound in the large room the new Austrian company shared with Cardas, Profundo, and the Jeff Rowland Design Group was superb, but that's a lot of change, even if the manufacturer will fly anywhere in the world to set the speakers up in the customer's home. (The rest of the system comprised a dCS Puccini used as a transport to feed JRDG's new Aeris DAC (the Colorado company's first digital product), $9800; a JRDG Criterion line stage, $18,500; and two JRDG 625 stereo power amplifiers, $13,500; with Cardas Clear cabling.

Each 12" woofer uses a fiber-glass–reinforced paper cone and is loaded by what is referred to as "a hybrid form of horn-resonator and bass reflex design." The mid/HF module is coupled to the woofer modules with spheres of varying hardness, to drain vibrations optimally, and can be adjusted to bring the drivers into proper time alignment at the listening position. The midrange unit features a papyrus cone with an elmwood phase plug and an alnico magnet, while the enclosure is filled with wool from "locally raised sheep" to reduce internal reflections being retransmitted through the drive-unit cone. The tweeter uses a titanium nitride dome loaded with a Tractrix-flare horn, while the supertweeter is a diamond-diaphragm type. The upper-range crossover is passive; the woofers are fed via a line-level crossover, and internal wiring is all Cardas Clear.

Joining WireWorld, Thiel, and Bryston in their impressive exhibit in the Sands/Venetian Convention Center was power specialist Plitron. Based in Canada, the company has spent 28 years in R&D and manufacture of toroidal transformers that are utilized by many of the leading companies in the audio industry. Five years ago, Plitron decided to introduce their own Torus Power line to demonstrate their full implementation of their work with toroidal isolation transformers and power conditioning.

Arthur Kelm, formerly chief engineer in a number of recording studios including Record One, the Record Plant, and Skywalker, designed the Torus Power Ground One power conditioner panel that uses Plitron transformers. “I have known that power is the foundation of every audio/video system,” he explained. “It’s also the most misunderstood application you have. People just don’t understand power and its importance.

“The major advantage of using an isolation transformer is that you now have a very low impedance to plug into, and you can rebond neutral and ground which is where 90% of your noise comes from in electrical systems.”

The complete Torus Power line includes units from 2.5 amps up to 300–400 amps. The lowest priced unit, the RM 2.5 ($999), handles 2.5A. The company’s most popular units, ideal for dedicated audio systems, are the RM 15 ($2000) and RM 20 ($3000). There is also a custom installation series with 60A and 100A units, plus Ground One panels for use in all-home AV and theatres. Some models include automatic voltage regulation.

As a former owner of KLH Nines and original Quads, I have a fondness for electrostatics. MartinLogan has taken the hybrid approach, using electrostatic mid/tweeters and powered dynamic woofers, and this has worked well for them. The latest feature of their approach is the use of DSP equalization, used in the Ethos. This is now being applied upmarket, and the speaker incorporating this approach, now in advanced prototype form (“two or three months from being ready for production”), on demo at CES was a speaker that is expected to sell for $9000–$10,000/pair. The sign said Summit X Jr., but I was told that was just an interim name. The speakers certainly sounded most promising.

Peachtree was showing off its new iNova integrated DAC/preamp/amplifier, the replacement for their best-selling Nova. The iNova upgrades some parts from its predecessor including better capacitors, a 24-bit/96kHz USB input and an upgraded iPod dock. The amp is rated at 80Wpc and will sell for $1799.

The iNova was hooked up to the brand new Aerial 7T speakers, which employ some major cosmetic, and structural changes from previous Aerial speakers. The 7T ($9850/pair) is a three-way loudspeaker, nominally rated at 4 ohms and 89dB sensitivity. The finish on the cabinet, made from MDF bent to shape, was excellent. (Though the enclosures are made in China, the speakers are manufactured in Aerial’s Massachussetts facility.) Playing files from a server to the iNova, Aerial 7T sounded huge and clear with fantastic bass extension and articulation.

I was impressed by the fact that the Peachtree was able to drive these speakers with such scale and authority.

mbl products always make you wonder, is it technology I'm looking at or art? Their new Corona Line continues this tradition with, depending on your taste preferences, some of the most drop-dead gorgeous casework you'll see in the audio world, or some of the most over-the-top gratuitous metal (choose between gold or palladium alloy palinux), paint (white or black) and gloss this side of a Kustom Kar show.

Nonetheless, you can't argue with how carefully these products are made. The C31 wil be available sometime this summer for around $8,000 (depending on exchange rate at the time) and has coax, toslink and USB inputs in addition to its disc playing function. The C31 can also communicate with the other products in the Corona line via the SmartLink ethernet connector on the back
