Steven Hill, designer and owner of Straight Wire, has released his new Expressivo line of speaker cable ($700/8 ft pair). The cables, which contain four conductors surrounded by multiple spiral shields, include a compressed conductor of special OFHC certified copper and a spiral polyethylene rod that encapsulates the conductor. The net result of his geometry is that the spiral rod only touches the conductor group in a small area, resulting in an effective air-spaced dielectric.
Hill claims that Expressivo’s soundstaging, imagery, and detail retrieval surpass those of his Maestro speaker cable. Expressivo occupies the middle of Straight Wire’s loudspeaker cable line, with three lines above it. The company’s full range of cables ranges in price $1/foot to $150/foot for speaker cable, and from $15 to $900/1m pair of interconnects.
Cable manufacturer Kubala_Sosna has been in business eight years, with business expanding each year. This year, the company’s products were in use in 12 rooms at CES.
Just introduced are two new digital cables, the Emotion S/PDIF ($1500/first meter, $300/each additional meter) and Elation S/PDIF ($2700/first meter, $400/each additional meter). Both cables are a step up from Kubala-Sosna’s previous Expression level.
“We’re raising the bar, no doubt,” said keen recordist Joe Kubala (pictured on the right). In perfect agreement was partner Howard Sosna (left), who designs the cables in collaboration with Joe.
With the new cables used to connect the PS Audio Perfect Wave Transport to the Perfect Wave DAC, I heard impressive bass and captivating warmth coming through the not-too-shabby Tenor Audio Reference 350M monoblocks ($100,000/pair) and Estelon Model XA loudspeakers ($43,900/pair) from Alfred & Partners in Estonia. Of course it helped that Estelon’s entire line is internally wired with Kubala-Sosna.
Derived from Finite Elemente’s Emperor rack, the Soundbase equipment shelf ($1800) is filled with aluminum foam whose random patterning allows it to absorb energy and dissipate it as heat. Immedia’s Stirling Trayle notes that the shelf works as well for turntables as for other components.
Each Soundbase comes complete with four Cerabase Slimline coupling feet that use a combination of three internal ceramic ball bearings and stainless steel for ultra-efficient energy transfer. The Cerabase Slimlines are also sold separately for use under components ($550/set of four). Their three internal ceramic balls represent an advance in “resonance deflection” technology for the company.
Synergistic Research’s Ted Denney was eager to show off the great midrange and bass transmitted by his Galileo System of hand-built cables. His choice of music: Michel Jonaz’ “Le Temps Passé,” a classic recording whose abundance of space and choice of contrasting, slightly gimmicky instrumental timbres makes for one of those ideal audiophile demo discs.
The Galileo System of cables includes speaker wire ($40,000/8ft pair) and interconnects ($25,000/1m pair), the PowerCell LE (limited editiononly 20 are being built for $10,000 each), and the Galileo Element series. All cables work universally, with switchable XLR and RCA terminations. If you switch gear from single-ended to balanced, you don’t have to buy an entirely new set of cables with different terminations. Very neat.
Nate Mansfield, Sales Manager of Kimber Kable, happily showed off the company’s newest products, the complete line of Kimber Select KS 6000 series speaker cables ($4400$18,800/8ft pair, depending upon level and wiring). Introduced in prototype form at CES 2010, the KS series has been shipping for the last six months, and is available in either all-copper, copper-silver hybrid, or full silver configurations. Designed by Ray Kimber, the cable also features a new multi-layer braid that combines stranded and solid core conductors in the same cable. The Kimber Select KS 6000 series represents a technological evolution of the old Black Pearl 88, a highly regarded all solid-core cable which Kimber manufactured in the early 1990s.
Furutech is introducing a new speaker cable brand in 2011, ADL, Alpha Design Labs. Designed to make OCC cable products available to entry-level buyers, ADL cables are the lowest priced cables in Furutech’s current line-up. Prices start at $100/1m pair interconnects, with USB and LAN cables going for around the same price.
Pictured is Furutech’s Flux series of cables, which was introduced last year. The Flux power cable runs $1200/6ft, while speaker cables cost $2000/2m pair. On the left is publicist extraordinaire Jonathan Scull, standing aside Furutech’s Graeme Coley. Also present, albeit unpictured, was Furutech’s Engineer and VP, Frank Yoo.
Joe Skubinski of JPS Labs introduced its first two USB cables, the Superconductor Q USB (approximately $399/1m) and Superconductor 3 USB (approximately $799/1m). The cables are so new that Skubinski had to guess at the prices. Both boast a precision twisted-quad design with dual shields and gold-plated connectors.
Skubinski’s design goals were to transfer the digital signal as flawlessly as possible without radiating noise into adjacent cables. As I left the room, he and the folks from Usher loudspeakers were about to conduct an experiment to see if the Superconductor 3 could successfully transmit music recorded at 352.8kHz.
Allen Sung, owner of XLO (left), introduced the Purple Rush power cord ($7000/6ft). The first product in the company’s new Purple Reigns series, this substantial baby is heavy enough to easily yank a poorly positioned component off the shelf. IMHO, the cable’s oversized proprietary connectors are as impressive as its girth.
XLO’s designer, Jay Victor (right), explained that he wanted to design a power cable that he could use on high-current power amps in his own system. “I started dabbling in cable design when I was in charge of product development at Monster Cable with Demian Martin,” he said. “We were marveling at how much of a difference different power cables made to a system’s sound. I kept refining my ideas of power cable design, until I came up with idea of mixing different conductor shapes to best convey the whole range of bass sound.”
Victor believes that a large solid conductor is great for low bass, a flat conductor is best for mid bass, and a polymer coated Litz works best for highs and transients. He has combined all three in the Purple Rush power cord. The cord also employs an exotic field-balanced winding technique to lower the noise floor and cancel magnetic effects. All in all, five patents are associated with the Purple Rush power cord, which took eight years to develop and refine.
George Cardas stands darped in the new Cardas cables whie the company's Operations Manager Josh Meredith was happy to show off Cardas’ Clear Light Speaker cable ($1048/2m pair). Now the lower end of the Clear speaker cable line, it will soon move up a notch to middle position as another model of speaker cable comes out.
A simplified version of Clear speaker cable ($3726/2m pair), its ability to be produced more rapidly results in its considerably lower price.
Also on hand was the Clear Light Rev 1 interconnect ($856/1.5m pair). Now with a larger diameter, improved shield, and nicer RCA connector, it is still substantially lower in price that the Clear interconnect ($2360/1.5m pair). Next on the horizon is a Clear power cable.
Audiophile sensibilities have long found a comfortable home inside George Cardas’ head. Also in George’s head for the past two years has been the design of a single-driver, dynamic in-ear monitor that would fulfill his desire for a non-fatiguing portable listening experience. The as yet unnamed little gems are just entering production, and are expected to retail in the $300$500 range. A quick listen confirms that George has indeed managed to do something quite special: glorious midrange. I gladly accepted a sample pair for review; I reckon I’ll be spending a good chunk of time with George’s thoughts and sound in my head very soon.
