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.
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.
To celebrate the 25th anniversary of Purist Audio Design, founder/designer Jim Aud has just introduced their 25th Anniversary cable. Shown at T.H.E. Show for the first time, the 25th anniversary line consists of interconnects ($8100/1m pair) and speaker cable ($18,000/1.5m pair).
“Basically we’re using solid silver, single crystal wiring surrounded by Ferox 103, which is a proprietary doped silicon,” Aud explained. “Our other cables only use copper or copper alloys, and don’t use the Ferox 103.” While Purist still makes two cables that contain fluid, the 25th Anniversary cabling does not.
Symposium Acoustics has released its upgraded Turntable Top Aircell Level ($1499). Designed to be used with Symposium’s visually arresting Isis Rack, the Turntable Top provides isolation and damping through four AirCell isolators that are level-adjustable for off-center loads. This means that if you have a table or transport with a heavy motor or power supply on one side, you can still level the shelf. Leveling is accomplished via four small underside holes, one in each corner quadrant of the platform, that are accessed with a supplied 1/8” Allen key.
Gary Koh of speaker manufacturer Genesis was happy to show off the new Absolute Fidelity Interface cables. Being sure to note that the product does not use the Genesis name, because it has been designed to be used with all loudspeaker brands, it has been give its own dedicated Absolute Fidelity website.
“To me, a cable should not function as a component; it should be an interface between two components,” said Koh. “Since every component is different, and draws power differently, I’ve designed different cables to interface between different components.”
The Absolute Fidelity Interface line currently includes the Loudspeaker Interface ($3000/2m pair); Turntable Power interface, Amplifier Power interface, and Component Power interface (each $1800/1m pair); and Component Interface (for use between source components, $1800/0.6m pair).
Koh explained that, a few years back, when he could not find a cable sufficiently transparent to do full justice to his Genesis 1.2 loudspeaker, he began rolling his own. Steve McCormack and a few other designers he works with were so impressed with the cable that they urged him to market it.
“I didn’t really launch them,” Koh said with a smile. “They just started selling. You can call this the official launch.”
Distributed for the first time in the US by Robert Kelly of Kelly Audio Technologies in San Diego, the unusually designed Bertram cable comes in copper, silver, and gold configurations. Pictured is Proxima 2 balanced silver interconnect ($8000/1.5m pair).
Designed by Soren Bertram of Denmark, Proxima 2’s silver ribbon wire is flattened and twisted into what looks like a braid. Boasting an air dielectric and laser-welded terminations, it is third down from Bertram’s top-of-the-line. Also available are the Proxima 2 silver speaker cable ($25,000/2m pair), signal cables, and power cords.
Some readers may recognize Kelly as the former speaker designer for EgglestonWorks and Cello. Out of the business for a number of years, he has returned with an intriguing portfolio of Scandinavian-sourced products.
Kerem Kücükaslan, whose surname means “Little Lion,” was born in Istanbul, where he resides for at least part of the year. Fluent in English, he received his BS in industrial engineering at WPI and a minor degree at MIT.
Kücükaslan founded Echole four years ago in New Hampshire. On display at T.H.E. Show was the complete line of Obsession Signature: speaker cable ($11,000/6ft pair), interconnects ($7500/3ft pair), and power cords ($6850/6ft).
Parts for Echole’s two cable lines, Echole Obsession and Echole Obsession Signature, are manufactured in both the US and Turkey. The wire, which is manufactured in Japan, consists of a proprietary ratio of silver, gold, and palladium. (The Obsession line has less gold and palladium that the Obsession Signature).
Glenn Phoenix, President of Westlake Audio, was touting the loudspeaker company’s cable muffs. Made of foam, the muffs are used to support and separate cables. They are also said to benefit cables that are under-damped.
“We have a rule in the company to keep cables between 2” and 4” apart,” he said. “Putting left and right channels too close together can increase crosstalk, while positioning them too far apart may lead them to generate and pick up interference.” I hope I got that right.
Westlake Audio manufactures cable muffs with a number of different size holes and slots to accommodate a wide assortment of cables other than the extremely thick variety. Prices range between $59.50 and $88/set.
Debuting at CES 2011, Running Springs Audio’s Elgar Powerline conditioner is so new that Dan Babineau has yet to produce product literature. A trickle-down, opening price-point piece ($999/6 outlets), it can handle 1800W maximum. The 100% passive, noncurrent-limiting design employs the same filters as all other Running Springs Audio products, but uses a smaller-laminate inductor to increase dynamics.
Designed for smaller, modest systems, the Elgar Powerline conditioner is hand-built in Anaheim, CA. “It does three things really,” Babineau said. “A high quality circuit breaker, it also takes care of atrocious noise anomalies, and cleans up the power without negatively affecting the source. This has always been my goal since I started the company ten years ago.”
Jim Fosgate’s forthcoming Signature headphone amplifier (right), scheduled for release in the second quarter of 2011, has an industrial design that echoes his Signature phono stage (left). Combining a tube input stage with a solid-state output, it will include a loudness control, spatial enhancement circuit, and built-in DAC. Scheduled for distribution by Musical Surroundings of glorious Oakland, CA, its price has yet to be determined.
