CES 2011

Herbert Wong and Alex Yeung manufacture Gutwire cables near Toronto, Canada, where they live. All Gutwire cables, which are distributed by May Audio, are made of triple-braided copper, and all terminations are crimped without solder.

“We find copper is more natural and musical-sounding,” Herbert explained.

The photo shows the newest additions to Gutwire’s cable line. The power cable is the SP Crystal Edition AC cable ($1800/6ft), which lies in the middle of their price spread. Also shown are the EON-Z interconnect ($1600/1m pair) and UNO-S interconnect ($2500/1m pair). By way of comparison, the prices of the company’s top-of-the-line are as follows: the SP-18.1 AC cable ($7500/6ft), Uno-S interconnects ($2500/1m pair), and digital SD-3-SE ($1150/1m).

The terminations on Gutwire’s novel top-of-the-line SP cabling contain Bincho-Tan (white charcoal). Bincho-Tan emits negative ions, absorbs RF and EMI. Herbert first discovered the substance in his water purifier. Intrigued, he began to research it on the net, and learned about its other properties.

Gutwire also manufactures two 4 and 6 outlet power conditioners, the 4 Bar and 6 Bar ($1100–$2600, depending upon the model). Each contains a passive filter, and the top of each is milled from a block of solid aluminum.

In a brief demo, I was struck by Gutwire’s ability to transmit a lovely smooth midrange on the classic recording of Harry Belafonte at Carnegie Hall.

Touraj Moghaddam, based in Windsor, UK, near London, manufactures the relatively new TM Systems Pulse cables. The complete line includes tonearm wires and internal wiring for loudspeakers.

Not yet distributed in the US, Moghaddam’s handmade interconnects ($8000–$9000/1.1m pair) will be followed in February or March by the machine-made Pulse R interconnects ($4000–$5,000), which include special proprietary connectors made of copper alloy. Below them, Pulse B and Pulse C entry-level interconnects are in the works.

Veteran audiophiles will recognize Moghaddam as the 25-year veteran designer of Roksan turntables and loudspeakers. He began designing and manufacturing Pulse cables three years ago after he discovered that some Roksan ‘tables were being used with incompatible cables.

Gary Koh of Genesis, who had invited Moghaddam to exhibit his cables in the Genesis room, noted that they both attended the same college in England 25 years ago. “And now, 25 years later, we discover that we are both making our own cables because of similar concerns, such as their incorrect use by some people as tone controls,” he said.

As a former owner of KLH Nines and original Quads, I have a fondness for electrostatics. MartinLogan has taken the hybrid approach, using electrostatic mid/tweeters and powered dynamic woofers, and this has worked well for them. The latest feature of their approach is the use of DSP equalization, used in the Ethos. This is now being applied upmarket, and the speaker incorporating this approach, now in advanced prototype form (“two or three months from being ready for production”), on demo at CES was a speaker that is expected to sell for $9000–$10,000/pair. The sign said Summit X Jr., but I was told that was just an interim name. The speakers certainly sounded most promising.

The first speaker I reviewed for Stereophile was the Alon IV by Acarian Systems, designed by Carl Marchisotto . I remember it as being a very good-sounding speaker, with outstanding bass, and the dipole midrange giving it an “open” sound. Through the years, for business reasons, the speaker brandname has changed (Nola is Alon spelled backwards), and the company is now called Accent Speaker Technology, but the speakers are still designed by Carl, and his wife, Marilyn, is the company’s wife president. Carl’s more expensive speakers still use the dipole midrange arrangement, but in the more affordable line he has turned to the more common unipolar approach, albeit with his own variations, like separate porting of bass drivers. The latest such speaker, introduced at the 2011 CES, is the Contender ($3400/pair), and it sound like. . .well. . .a real contender.

I first encountered the glass-enclosured Force dipole loudspeaker from Perfect Eight, which combines a full-length ribbon with 8 cone midrange units and a subwoofer handling the load below 60Hz, at the 2008 CES. Their 2011 dem, with the speakers driven by Ypsilon amplification, was noteworthy for having invited Ray Kimber to talk about and play some of his IsoMike recordings. (Ray is seen here on the left in my admittedly rather grainy photo—it was dark—with Perfect Eight's Jons Rantila.) I listened first to soloists from the Academy of St. Martin-in-the Fields performing a movement from the Mendelssohn Octet, then to a Mozart piano sonata movement by Robert Silverman (the latter one of my "Records to Die For" in the February 2011 issue). Despite my skepticism about glass as an enclosure material, the sound was natural and uncolored.

The Estelon speakers from Alfred & Partners ($43,900/pair) were one of the hits of last year's RMAF, so I made a point of taking a listen to them at CES. The ceramic-diaphragm floor-standers were being used in more than one room—Conrad-Johnson was also using them, in their first "live" Show dem in two decades—but I was drawn into the Kubala-Sosna room by the sound of Jimi Hendrix playing "Born Under a Bad Sign." Source was a Korg DSDx2 recorder, which Joe Kubala had used to record the track from LP, and the sound, with Audio Research Reference 5 preamp, Tenor 350M monoblocks, and Kubala-Sosna Excitation cables, was rich, full-range, and clean. The speakers are internally wired with K-S cable.

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:
