LATEST ADDITIONS

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 300–400 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.

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.

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.

“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.

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.

TAD didn't appear to be demonstrating anything new in their large penthouse suite at the Venetian, but designer Andrew Jones was getting such an enormously involving sound from the Compact Reference CR-1 stand-mounts ($37,500/pair plus $1800/pair for stands) that I had to stop to take an extended listen. Jones had some of HDTracks' new 24/192 files that he was playing with Amarra and one track, featuring Hammond organ, double bass and drums, had the audience stumped. (The fellow in front of me even held up his iPhone and ran a song ID app, only for the screen to flash "No Match.") Then I twigged: it was a jazz arrangement of Pink Floyd's "Money," with sound to die for. DAC, preamp, and power amps were also from TAD.
