CES 2013

While the sound and music in Philip O’Hanlon’s On A Higher Note systems is uniformly excellent, I had an especially good time listening to his smaller desktop system: MacBook running Audirvana, a pair of passive Eclipse desktop speakers, and Luxman’s new DA-200 USB DAC/preamp and M-200 stereo amp ($2790 each).

I sought out Manley Labs, manufacturer of tube amplifiers and preamplifiers, at CES. The system in their room included a Music Hall mmf-2.2le turntable, the Chinook phono stage that impressed Michael Fremer last August ($2250), a Steelhead phono preamplifier ($8000), a pair of Snapper monoblock 100Wpc tube amplifiers ($7650/pair), which use four EL34 output tubes, driving Neat Acoustic Ultimatum XLS speakers. EveAnna Manley mentioned after the show that she was working on a secret, prototype1 DAC that promises "to beat all comers." I greatly enjoyed the audio I heard in the Manley Labs room at CES. I had to agree with the saying on the rug that appears at every Manley abs exhibit: "Tubes Rule!"

The Phoenix, a large, attractive-looking three-way design with ceramic-diaphragm drivers, can be had in passive form for $75,000/pair or in active form for $95,000/pair. The active form includes a 500W class-D amplifier for the woofers and incorporates the Rives PARC low-frequency equalization. Demmed with VAC amplification driving the HF and MF sections, the active Phoenixes worked well on Charles Mingus Mingus, Mingus, Mingus, Mingus album, the low end sounding more evenly balanced than in most other rooms.

I had auditioned the Estelon X-Diamond speakers ($65,000/pair) at the 2012 Newport Beach Show, but the room there was not allowing the speakers to sound at their best. Driven by top-of-the-line, class-A Vitus amplification, these speakers, which use the 1.2" Accuton inverted diamond-dome tweeter, along with a 7" Accuton ceramic-cone midrange unit and an 11" Accuton ceramic-cone woofer, sounded much better at CES, even though the dem room was one of the infamous split-level rooms at the Venetian.

Invented by Oskar Heil and made popular by speakers under the ESS name in the ‘70s, the Air Motion Transformer (AMT) tweeter and midrange have lost popularity for a while, but have made a major comeback in speakers made by a number of manufacturers, including ADAM Audio in Germany. The Column Mk.3 ($7000pair), reviewed by Kal Rubinson in August 2012 was used by Cary Audio at CES, and had what I now think is a sonic signature that’s apparent in a variety of loudspeaker designs: low in coloration and detailed without being overly bright.

Although a number of speaker manufacturers use Heil AMT drivers, only one company has the rights to use the name of the original speaker company that used Heil drivers: ESS. Headquartered in South El Monte, CA, ESS Laboratories LLC (which we might call “ESS Reborn”) also owns the rights to the original slogan, “Sound As Clear As Light.” Unlike the speakers by ADAM Audio, GoldenEar, etc., these speakers look just like the original ones from ESS. President and CEO of ESS, Ricky “Rico” Caudillo, seen in the photo, told me that he wanted to stay with the original, highly-successful designs, but in recreating these designs managed to improve them in a number of ways, most notably in producing wider dispersion. A brief listen to the LD12 ($3295/pair), modeled on the original ESS Monitor, left me with a very positive impression.

Distributed in the US by Colleen Cardas Imports, the new Moos Mini Aero speakers ($2499/pair) represent a serious attempt to get good sound from powered wireless speakers. Founder of the Australian company, Tom Celinski, shown in the photo and once with Linn, told me that the two drive-units are ScanSpeak Revelators and, in fact, the speakers are assembled by ScanSpeak. A USB2.0 interface guarantees bit-accurate transmission of digital audio at up to 24bit/96kHz. The wireless data are fed to a DSP-based digital crossover running on Analog Devices SHARC floating-point chips. Thee crossover in turn feeds the data for each drive-unit to a quad mono differential Wolfson DAC which drives a Hypex 200W class-D amplifier module. The sound was open and spacious. The speaker, which was honored with an International CES Innovations 2013 Design and Engineering Award, is scheduled to start shipping in April.
