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.

Scottish manufacturer Tannoy was showing the Carbon Black version of the Kingdom Royal speaker ($85,000/pair), which adds carbon-fiber trim panels, individually machined metal components, and a “specially formulated” paint on the cabinet surfaces. The speaker combines a 12” Dual-Concentric driver with a supertweeter and a 15”, vented woofer with a corrugated surround for maximum linearity. The Kingdom Royal looked elegant indeed, and driven by Cary single-ended power amplifiers with Cary’s new streamer as source, the full-range, wide-dynamic-range sound was equally elegant.

The Belgian Venture company introduced its Vidi speaker at CES. Costing $30,000/pair, the floorstanding, three-way Vidi speaker combines two 4" midrange units with a 1" tweeter and two 7" woofers, these mounted on the speaker’s sidewalls. All the drive-units use AGC (Abaca Graphite Composite) diaphragms. The crossover operates with first-order slopes at 250Hz and 3kHz and the speaker is specified as having a frequency range of 30Hz to 40kHz. Used fullrange but with an AW500 subwoofer also operating below 70Hz, the beautifully gloss-finished Vidis did a creditable job with the the live Bootleg Series recording of Bob Dylan’s "Desolation Row," played back from a laptop running the XX HighEnd software feeding digital data to a Weiss Medusa DAC. The opening up of the soundstage as the initially mono recording, made with a Nagra tape recorder, was spliced to the stereo backup tape when the Nagra ran out of tape, was delicious.

Jon Iverson already reported on the Antelope DAC, but as I have just favorably reviewed their SCM 7 v.3 minimonitor for the forthcoming April issue of Stereophile, I was more interested in the active ATC SCM100SL Towers in the room. This speaker combines ATC's proprietary soft-dome midrange driver with a 1" tweeter and 12" woofer, tri-amped by ATC's Anniversary amplification. With a laptop running JRiver Media Center feeding data to the Antelope Zodiac-Platinum DAC with its Voltikus power supply, the 24/96 transfer of Steely Dan's "Babylon Sisters" was reproduced with tight, well-controlled low frequencies.

Like Stephen Mejias at the 2013 Rocky Mountain Audio Fest, I have been impressed by the German Zellaton speakers when I have heard them, both at shows, and at a dealer event I attended in 2012 at Fidelis Audio in New Hampshire. With foil-covered drive-units, a crossover from Duelund Coherent Audio, and driven by Trinity balanced phono and line preamps and 200Wpc CH M1 amplification from Switzerland, the three-way Reference speakers sounded forceful and detailed.

"One touch," that’s all it takes for you to enjoy your music, said B&O CEO Teo Mantoni, introducing the Danish company’s BeoSound Essence music-streaming system to the press at CES, and compared that one-touch solution to the current compendium of 10 swipes and presses that you need to playback a Spotify playlist from your smartphone. Mr. Mantoni is holding the elegant Essence Remote in his hand; a ring around the small aluminum puck controls volume and play/pause, forward and backward buttons are embedded on the top. The circular puck is available as wall-mount and desktop versions, and a remote box both connects to the playback system and is the center for AirPlay streaming, DLNA streaming, Spotify Connect, QPlay and Internet radio stations.

I’ve had a couple of conversations the past couple of years with mastering engineer Dave Collins about the D/A processor he was designing for Manley Labs, the company run by his wife EveAnna Manley. The 2014 CES saw the consumer debut of the Heart Monitor Controller 24/192 DSP ΔΣ [Delta-Sigma] DAC, which was being demmed in a system featuring Manley’s 25th Anniversary monoblocks, which use KT120 tubes. There are four digital inputs and Dave has kept the fully differential signal path as short as possible. Silicon includes a SHARC DSP and AD1955 DAC chips and harmonic distortion has been kept to a superbly low –120dB, and even that is the subjectively benign second. Price has yet to be decided.

Jon Iverson reports elsewhere on Light Harmonic's cost-no-object Sire DAC. But the bigger buzz at the 2014 CES was the LH Labs Geek Pulse, a desktop DAC and headphone amplifier. Except that this product does not yet exist!

The CES is traditionally where we give awardees their well-deserved Products of the Year awards. Here is the complete line-up for 2013, waiting in the Stereophile room at the Venetian, just before the show started on Tuesday January 7.
