Gutwire's Good Cables
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.
Torus Power from Plitron
Joining WireWorld, Thiel, and Bryston in their impressive exhibit in the Sands/Venetian Convention Center was power specialist Plitron. Based in Canada, the company has spent 28 years in R&D and manufacture of toroidal transformers that are utilized by many of the leading companies in the audio industry. Five years ago, Plitron decided to introduce their own Torus Power line to demonstrate their full implementation of their work with toroidal isolation transformers and power conditioning.

Arthur Kelm, formerly chief engineer in a number of recording studios including Record One, the Record Plant, and Skywalker, designed the Torus Power Ground One power conditioner panel that uses Plitron transformers. “I have known that power is the foundation of every audio/video system,” he explained. “It’s also the most misunderstood application you have. People just don’t understand power and its importance.
“The major advantage of using an isolation transformer is that you now have a very low impedance to plug into, and you can rebond neutral and ground which is where 90% of your noise comes from in electrical systems.”
The complete Torus Power line includes units from 2.5 amps up to 300400 amps. The lowest priced unit, the RM 2.5 ($999), handles 2.5A. The company’s most popular units, ideal for dedicated audio systems, are the RM 15 ($2000) and RM 20 ($3000). There is also a custom installation series with 60A and 100A units, plus Ground One panels for use in all-home AV and theatres. Some models include automatic voltage regulation.
TM Systems: New Name; Familiar Face
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.
Music Hall's Leland Leard
Bob Deutsch captured this image of Music Hall’s Leland Leard, an image equal to that which I hold in my mind. Anyone who knows Leland Leard will agree that Bob Deutsch released the shutter at just the right time. Say the name, “Leland Leard,” and I will see this wild, carefree smile. Leland would have just finished talking about the new Seu Jorge album or the USB-1 turntables he’s sold to Chicago’s Dusty Groove or the beautiful girl down the hall.

Here, however, Leland is demonstrating how to expose the old-fashioned baffle which hides behind the Epos Epic 2’s slick baffle cover.
People say that Leland and I look alike, but I don’t see the resemblance. Leland wears tighter jeans and frillier shirts, and has a much better smile.
New MartinLogans
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.

Revamped Polks
“What’s new?” is the question that comes up first with established manufacturers when considering whether there’s something worthy of a blog item. In Polk Audio’s case, the answer was “Everything!” According to Polk rep, Jim Crowley, their entire home audio line has been revamped, with changes in the cabinetry, drivers, and crossovers. Perhaps the most significant change is that now, for the first time, some Polk speakers feature a midrange driver. And with all that, Polk loudspeakers continue to be reasonably priced: the pictured LSiM is a modest-by-audiophile-standards $4000/pair.

Nola's Contender
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.

New from Peachtree & Aerial Acoustics
Peachtree was showing off its new iNova integrated DAC/preamp/amplifier, the replacement for their best-selling Nova. The iNova upgrades some parts from its predecessor including better capacitors, a 24-bit/96kHz USB input and an upgraded iPod dock. The amp is rated at 80Wpc and will sell for $1799.
Continue Reading »
The iNova was hooked up to the brand new Aerial 7T speakers, which employ some major cosmetic, and structural changes from previous Aerial speakers. The 7T ($9850/pair) is a three-way loudspeaker, nominally rated at 4 ohms and 89dB sensitivity. The finish on the cabinet, made from MDF bent to shape, was excellent. (Though the enclosures are made in China, the speakers are manufactured in Aerial’s Massachussetts facility.) Playing files from a server to the iNova, Aerial 7T sounded huge and clear with fantastic bass extension and articulation.
I was impressed by the fact that the Peachtree was able to drive these speakers with such scale and authority.
Ray Kimber Keynotes for Perfect Eight
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 photoit was darkwith 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.
