LATEST ADDITIONS

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.

“Go check out the Constellation Audio room,” said Jon Iverson. So I did. As I entered the room filled with unworldly looking gear I spied Michael Fremer, engrossed in one of his famous mix CDs, burned from his vast vinyl collection. Michael, ever the gentleman, relinquished the sweet spot to me and both of us took in some big, clean, transparent sound. Driving a pair of $150,000 Tidal speakers was Constellation’s Hercules amplifiers ($70,000 each), which are each able to put out a kilowatt of juice into 8 ohms and runs its first 250W in class-A.

The visual design of the amps is both striking and understated, clad in an all aluminum chassis. Each side of the amp has a diffuser grid which hides the amp’s heatsinks and allows for a chimney action to help cool the amplifier. All that aluminum also serves the purpose of mass-loading the amps to control vibration. Internally the amps mechanically float the sensitive signal carrying parts. That attention to vibration damping could be heard as stillness and ease, particularly when I played a high-resolution file of Robert Silverman playing the final fugue from Brahms’ Variations on a Theme by Handel. My time in the Constellation room was stellar.

The Metrodome may have collapsed but Minneapolis-based Bel Canto sure hasn’t. Brand new at CES is the C5i, a DAC/integrated amp/headphone amp that sells for the feel-good price of $1895. The amplifier, said to be stable into 3 ohm loads, puts out 60Wpc into a 8 ohms. The amp also includes two S/PDIF digital inputs, a USB input capable of handling 24bits/96kHz data, a moving-magnet phono input, an RCA line input and a headphone amplifier. I marveled at this little gem’s price but also its sound as it played files from a nearby laptop driving a pair of Joseph Audio speakers. This was my first room of CES 2011 and it was a great start!

Also on display was Bel Canto’s new headphone amplifier (shown right), a product so new it doesn’t yet have a proper model number or name. Bel Canto’s John Stronczer let me take a listen to the amp through a pair of in-ear headphones. The sound was lovely, but I couldn’t really get the cans to stay in my ears (I must have very large ear canals).

When I checked out the back of the headphone amp I noticed that it was in the signal path of the room’s big rig. The DAC3.5VBS’s outputs went into the headphone amp and the outputs of the headphone amp went to the rig’s amplifiers. I asked John, “What gives?” He told me that he has been experimenting with using the new headphone amplifier as a unity gain buffer, taking advantage of the headphone amp’s ultra-low output impedance. John said that he hears improvements in the system using this configuration and that Bel Canto is exploring new applications for this technique. No price has yet been set for this headphone amplifier.

Last year I marveled at the visual design of Resolution Audio’s Cantata Music Server. This year, Resolution debuts a new matching integrated amp, the C50 ($4000). The C50 puts out 50Wpc. According to Resolution’s Jeffery Kalt, on paper the C50 doesn’t look much different than most integrated amplifiers. However C50 benefits from custom capacitors, a unique application of feedback above the audio band, and a circuit layout that minimizes eddy currents. The C50 must be doing something right as it made a modest pair of Epos speakers sing with clarity, focus and body, sounding great song after song.

Aotearoa. The Land of the Long White Cloud. New Zealand. The home of the Maori, Kiwi birds, an upcoming shoot for Peter Jackson’s film The Hobbit, and Plinius Audio. On display in the Plinius room was the Hiato integrated amplifier ($9100). The Hiato is a 300Wpc integrated, able to kick out peaks of 50A of current. The amp is a high-biased class-A/B design that allows the first few important watts to benefit from class-A purity and then switch over A/B for greater efficiency and maximum power. The Hiato had me grooving to Stevie Wonder’s “Boogie on, Reggae Woman” and stopped me in my tracks playing a live duet version of Johnny Cash singing “Don’t Take You Guns to Town” with none other than Willy Nelson. The Hiato can also be installed with an optional phono preamp which brings the price up to $11,000.
