Back in January 2007, Bob Deutsch reviewed the single-driver Eclipse TD712z loudspeaker from Japanese manufacturer Fuijitsu Ten. He was impressed by what he heard from this idiosyncratic full-range speaker, but the brand never established a strong foothold in the US market. CES saw the reintroduction of Eclipse to North America, now distributed by On A Higher Note. A new version of the TD712z, the Mk.2, made its debut at the Venetian, along with the TD520W subwoofer. "Female voice—simply perfect!" I scrawled in my notepad, there always being special to the presentation when you dispense with a crossover.

Arcam used to CES to launch a “statement” integrated amplifier, the FMJ A49. Priced at $5000, the A49 offers 200Wpc into 8 ohms (with the first 50W in class-A), 400Wpc into 4 and features a class-G output stage, fully balanced topology, MM/MC phono stages, and a onboard power supply for Arcam’s rSeries of wired and wireless DACs. While Arcam’s lower-priced products are made in China, the new amplifier is the first products to be manufactured in the USA, at the parent company’s facility in Rochester, New York.

When I interviewed Thiel’s new owner Bill Thomas (right in photo) at the 2013 CES, he was bullish about the company’s future. However, I felt that future was going to be dependent on whom Bill hired to head up the Kentucky company’s engineering team. At the 2014 CES, Bill introduced me to that person, Mark Mason (left), who had come to Thiel from PSB, where he had worked alongside veteran speaker engineer Paul Barton. Bill and Mark are flanking the new TT3 speaker, which is intended to replace the CS3.7 as the company’s flagship when it comes to market in the late summer. Bill feels that with Mark now leading the engineering, Thiel can be taken to a larger customer base.

Yes, those are moving-coil woofers. From Martin-Logan, the electrostatic company. ML’s new Motion Series speaker, to be priced at around $3000/pair when it is available in the late summer, is a big brother to the Motion 40 tower. The speaker uses the largest yet Folded Motion XT tweeter to come from MartinLogan, marrying it to a 6.5" midrange unit and a pair of 8" woofers. and although the company is still based in Kansas, its speakers are now made in Canada. Though it was demmed with Peachtree amplification, the speaker suffered from the suboptimal room acoustics.

VANA’s Kevin Wolff was showing off the new Liszt speaker, which is expected to sell for $15,000/pair when it becomes available at the end of the first quarter of 2014. This impressive sounding speaker has been in development for two years and combines a new version of VA’s distinctive flat coaxial HF/MF unit with three woofers operating below 150Hz, these mounted in different sub-enclosures and loaded with two vents.

The German ADAM company has been developing the idea of the Air Motion Transformer HF unit, originally developed by Dr. Oskar Heil. The latest version of their tweeter, the X-ART tweeter, is featured in the Mk.II version of the Tensor Beta loudspeaker ($25,000/pair), which was being demmed with Cary electronics. The X-ART tweeter is married to a folded-ribbon upper-midrange unit, a new lower midrange unit and two woofers, all mounted on a solid aluminum baffle. The enclosure is made from 1” and 2” MDF panels, extensively crossbraced. Interestingly, waffle-shaped inner panels are loosely filled with steel shot, which absorbs vibrational energy. The speaker is also supported on fluid-filled feet to further absorb vibration.

With new US distribution, by the Katli Audio Co. from LA, the Taiwanese Usher loudspeaker manufacturer premiered its Grand Tower flagship ($37,800/pair) at CES. Combining Usher’s diamond-dome tweeter with two in-house 7" midrange units and two Eton 11" woofers, the Grand Tower weighs 500 lbs and has a claimed low-frequency extension of 24Hz, with a 90dB sensitivity. My experience of a percussion recording suggests that both specifications are valid!

The Polar Vortex weather and its associated flight cancellations prevented Convergent Audio Technology’s Ken Stevens from reaching Las Vegas until the third day of the show. However, once he arrived, he set up a system featuring Vandersteen 5A Carbon speakers, connected by Stealth cables to his new JL5 Triode "Baby CAT" stereo power amplifier. This 100Wpc (8 ohms) amplifier costs $12,000 with amorphous core transformers and Black Gate capacitors, $10,000 with silicon-steel transformers. The circuit features what Ken calls "OptiBias"—Ken describes this as "somewhere between constant current and constant power"—which keeps the bias current of the output-stage KT120 tubes independent of fluctuations in the AC supply voltage. Those who feel tube amplifiers can’t rock hard in the bass should have experienced the Led Zeppelin track I auditioned in Ken’s room.

On first glimpse, Nola’s Carl Marchisotto appeared to be demming the same Concert Grand Reference Gold loudspeakers he had shown at the 2013 CES. However, those were the preproduction protypes and the 2014 show featured the production version. Costing the same $197,000/pair, the speaker features a new ribbon supertweeter taking the response up to 100kHz and two new Gold Technology woofers operating below 40Hz. Driven by an Audio Research Reference 75 stereo amplifier and an Audio Research Reference 10 preamp, with source two United Home Audio Tape decks running 15ips, 2-track analog tape and hooked up with Nordost Odin cabling, the sound in this room had an impressive, full-range sweep that usefully loosened up as the show progressed and the speakers/system broke in.

Jason Serinus mentioned the Rosso Fiorentino Florentia loudspeakers ($99,995/pair) in his report on the Graaf amplifier in the Avatar Acoustics room below. This four-way speaker enclosure features aluminum front panels and glass side panels and weighs 361.5 lbs. The midrange and treble units are mounted in an open baffle, while the top-mounted woofer and the twin 12" subs are mounted in sealed enclosure. The subs are driven by a 1500W amplifier and the sensitivity is claimed to be 89dB.
