CES 2013

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.

The new Octave V110 push-pull pentode integrated amplifier ($8300) from Germany, distributed by Dynaudio, is a KT120-based product whose protection circuit is described as “bullet proof.” To demonstrate what that means, speaker wire terminations on one of the channels were intentionally crossed; not only did nothing blow, but the left channel, which was properly connected to a loudspeaker, continued to play. The Octave V110 is thus the perfect amp for folks who use battery cables to jump-start their cars, and then celebrate by clapping both clamps together.

I have been impressed by the sound of the line-source Scaena speakers at previous shows, but nothing had prepared me for the drop-dead gorgeous, real silver finish on the Silver Ghost 10th Anniversry Edition speakers at CES. Costing a breathtaking $153,000/system with the active subwoofers, the Silver Ghosts were driven at CES by the battery-powered Veloce amps and preamp and connected with the High Fidelity cables that Jason Serinus wrote about earlier in this Show report. (The regular speakers cost a relatively more affordable $83,000/pair.)

The German Voxativ Ampeggio Signature by Schimmel loudspeaker ($32,500/pair) was Stereophile's surprise Product of 2011, wresting well-balanced sound from its single drive-unit. At the 2013 T.H.E. Show, designer Inès Adler showed her Ampeggio Duo ($100,000/pair), which still uses a single full-range drive-unit, but this time field-coil–energized and with a wooden cone, said to have the same mass as a conventional paper cone but 100x stiffer. The large, wide, piano-lacquered enclosure horn-loads the rear of the cone and the speaker is claimed to have a –3dB point of 25Hz. Driven by KR amplifications, the 100dB-sensitivity Ampeggio Duos produced the kick drum on Dire Straits' "Sultans of Swing" with surprising weight.

According to T+A (Theory plus Application) ElektroAkustik's Lothar Wiemann, the manufacturer is one of Germany's largest electronics companies. (It is distributed in the US and Canada by Dynaudio North America.) This company makes the 1000 W M10 monoblock hybrid amplifiers ($33,0000/pair), where the output stage uses tubes to handle the voltage and transistors handle the current.

Have you ever attended one of those speaker demos where a large pair of floorstanding speakers were supposedly playing, and then it was revealed that the speakers playing were small hidden ones? (I recall Joseph Audio doing one of these.) Well, it was something like that in the Totem room, but not intentionally. The speakers that I thought were playing were the Metal floorstanders ($12,000/pair) and I was particularly impressed by the deep, dynamic bass produced by these speakers.

And then . . . in discussing the performance of the speakers with designer Vince Bruzzese, I found out that the speakers playing were not the Metals but the much smaller bookself-type Fires ($6000/pair) . . .

The synergy is palpable between Triode Corporation's Japanese-made electronics, distributed by Santo Oropel's Twin Audio•Video, and Acoustic Zen's loudspeakers and cables, masterminded by Robert Lee. At CES, Triode premiered the imminently available TRX-M300 8W into 8 ohms triode monoblocks (approx. $14,000–$15,000/pair). Built around a 300B tube driven by a 91A tube—there are one 300B, two 91As, and one 274B—the 60 lb monoblock includes auto-bias, and has a frequency response of 10Hz–50kHz, +0, –3dB.
