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.

Pride of place in the Avatar Acoustics room at the Venetian went to the four-way Siena speakers ($24,995/pair) from Italian manufacturer Rosso Fiorentino. The designer teaches electroacoustics in Florence, but is a graduate from the University of Salford in the UK. A pair of aluminum-cone 8" woofers in a separate sealed enclosure are combined with a 6.5" paper-cone midrange unit (a ScanSpeak Revelator), a 1" silk-dome tweeter, and what appeared to be a Murata "ultrasonic generator," to give a specified response of 35Hz–100kHz, –3dB.

The Siennas were demmed in a system comprising Dr. Feikert turntable and tonearm, Abbingdon Music Research CD player, phono preamp, and integrated amplifier, with Acoustic System racks and cables, but I will hand over to Jason Serinus for some additional thoughts:

The Paragon VL-2 Signature ($8600/pair) from Hong Kong-based Volent Corp. combines a unique dual-ribbon tweeter with a titanium/graphite-sandwich–coned woofer in an attractively curved enclosure filled with wool. Frequency range is specified as 30Hz–60kHz, impedance as 4 ohms, and sensitivity as 88dB/2.83V/m. Driven by MSB's M202 tower amplifiers and MSB digital source, the sound was much larger than I was expecting from these stand-mounts.

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.

Looking at the ginormous horn speakers in the Silbatone room, all I could think was "how did they get them through the door?" The speakers were a hybrid, the lower half being vintage Western Electric with field-coil–energized 18" woofers, and the midrange and highs being modern recreations from GIP in Japan.

I hadn't been aware of the Silbatone brand before this CES. Their website says that "The goal of Silbatone Acoustics is to recreate the musical enjoyment of the great theater systems in the home, creating practical realizations for today's serious music listeners." Okay. It turns out that their beautifully constructed power amplifiers ($150,000, depending on tube choice) are vehicles for unusual and rare tubes. The amplifier seen in front of the speakers, for example, used square-base Marconi DA100 broadcast modulation tubes (around $5000 each) for the outputs, with pre-WWII Siemens ED red-base tubes as the drivers. The audiophile air in this room was rarefied, indeed.

Internally, Ayre's new VX-R stereo amplifier features the same carved-from-solid-aluminum chassis construction as the famed MX-R monoblock. And that chassis is packed full!

The German T+A brand is now being distributed in the US by Dynaudio North America and having only been aware of their electronic products, I was surprised when I went into the T+A room at CES to see a large pair of speakers, the Solitaire CWT2000s ($45,000/pair). However, "I have been designing speakers since the company started," explained T+A's Siegfreid "Siggi" Amft, seen here with his creation.

The speaker features an electrostatic tweeter, 45mm wide but mechanically split into three 15mm-wide sections. as the frequency increases, the crossover increasingly cuts off drive to the outer sections, maintaining lateral dispersion. Adjacent to the tweeter is an array of six 6" cone midrange units, with the higher frequencies mainly being handled by the central units, again to optimize dispersion. Two pairs of 10" woofers complete the driver complem3nt, one pair being mounted each side of the enclosure and driven in-phase so that their reactive forces cancel. The sealed-box alignment is said to give a –dB point of 37Hz. Two more, smaller, less expensive Solitaire models will be launched later in the year.

The T+A speakers were bring driven by T+A M10 hybrid monoblocks ($33,000/pair), which use a tube input stage capable of delivering the full output voltage required by the speakers, with then a solid-state current amplifier providing the necessary cone-controlling grunt.

In prior Show reports, we have photographed Tidal's Jörn Janczak standing next to his speakers. But as Jörn stands 6' 8' in his socks, I made him crouch by the Sunray ($151,000/pair). so you can get an idea of how big this bi-amped speaker really is.

As at the 2010 CES, the rest of the system included two BAlabo 500Wpc stereo amps ($77,500 each), and the BAlabo BD-1 24/192 DAC ($37,500). Preamp was the BAlabo BC1 ($60,000) and the source was the Blue Smoke music server. Cabling was by Argento. I listened to a recording that many were playing at CES, piano/bass/drums jazz from the German Tingvall Trio, and was impressed by the effortless sweep of full-range sound produced by this admittedly very expensive system.

The Talon loudspeaker brand has been revitalized since it was purchased by Richard Rives Bird. Richard is see here with the new Phoenix, a floor-standing three-way with ceramic drive-units. The Phoenix costs $72,000/pair in passive form, which is what was being demmed at CES, driven by VAC amplification. The crossover is mounted in a separate compartment at the rear of the woofer section and an upgrade (approximate price $15,000) is planned whereby the passive crossover module can be replaced by one containing a line-level crossover, Rives' PARC bass equalizer to provide room correction, and a class-D amplifier to drive the woofers.

The Lotus Group's Granada speaker ($125,000/pair) combines 21st-century technology—a digital-domain crossover realized with DSP, including room correction—with distinctively retro loudspeaker engineering—frequencies above 200Hz are handled by a single Feastrex unit featuring a field-coil magnet and a paper diaphragm with a coincident "whizzer" cone. The paper used for the diaphragms is sourced from a Japanese "National Treasure" paper maker, Ichibei Iwano, and the surrounds are made from lambs' skin. Two woofer handle the bass and all three drivers are open at the back to give a dipole radiation pattern. There is also a rear-firing 0.75" dome tweeter to maintain the speaker's power response in the top octave. (The treble energy from the whizzer is emitted in a quite narrow frontal beam.)

My photo doesn't do justice to the beauty of this speaker; the rest of the system included Musical Fidelity AMS-50 class-A amplifiers, a Steve McCormack VRE-18 preamp, a Hanss T-10A turntable with phono stage and fitted with Dynavector DRT XV-1t cartridge,with interconnects and power cabling by Pranawire and speaker cabling by Acoustic Revive. Total system costs was $324,245! Listening to Joan Armatrading's "Show Some Emotion" then the Roy DuNann-recorded The Eleven LP by Art Pepper, I was struck by the effortless nature of the sound and the sheer musicality of the system, though I have to admit that instruments didn't quite sound tonally correct.
