CES 2011

“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!

All of Bel Canto’s equipment was powered by their VBS-1 Virtual Battery Supply ($1495), which effectively takes their equipment off the electrical grid. The VBS technology was debuted at last year’s CES, but new this year are the VB-Ref power cables which connect the 12V output of the VBS-1 power supply to the component. Having tried these cables out in my own system at home during my audition of the Bel Canto DAC3.5 VBS, I can testify to their ability to bring out the best in this new Bel Canto gear.

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.

The audiophile community was greatly shocked by the death, in September, 2009, of speaker designer Jim Thiel. My acquaintance with him was restricted to brief chats at shows, but he has always impressed me as a modest, gentle man, with a singular devotion to the pursuit of making the most accurate and musically pleasing speakers. Somehow, I thought he would always be around.

The Thiel/Bryston room had a system featuring the Thiel SCS4T ($3690/pair) speakers and a pair of new prototype Thiel USS subwoofers (price and delivery date TBD), partnered with Bryston electronics and digital source. The sound had that famed Thiel clarity, and an astonishing sense of depth on the well-known Misa Criolla recording. The SCS4T is the last speaker that Jim Thiel had a hand in designing: a fitting tribute to one of the greats of the world of audio.

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.

I think it was at least a couple of years ago that I first heard that Atlantic Technology—a speaker manufacturer that I associate more with value-for-money than cutting-edge products—was working on a patent-pending technology that combines reflex, acoustic suspension, inverse horn, and transmission line approaches to bass loading. Dubbed Hybrid Pressure Acceleration System (H-PAS), this is said to combine the best aspects of each approach, with deep bass extension, good system sensitivity, and reasonable enclosure size.

Well, the patent has been granted, and the floor-standing AT-1 ($2500/pair) is the first speaker to utilize the H-PAS approach. (According to Atlantic’s Peter Tribeman, they have licenzed H-PAS to five other companies—which he understandably declined to name.)

Having listened at CES to a pair of AT-1s, in a system that included top-of-the line Halo by Parasound electronics, I’m convinced that they’re on to something with this technology. The AT-1 is a modestly-sized floorstander, with two 5¼” woofer/midrange drivers, and yet it generated bass of such extension, power, and control that left me and others who attended the demo shaking their heads in disbelief. The sound was otherwise fine, too: tonally well-balanced (the bass was there only when it was on the recording), and a precisely-defined soundstage. Most impressive.
