Audience was demming their tiny ClairAudient 1+1 bipolar speaker ($1800/pair, available this month), driving them with their 400W Wavepower monoblocks $18,000/pair including Au24 SE PowerChords) via Au24 cables. Front end was a Bryston BDP-1 media player and BDA-1 DAC, and Audience’s Adept Response aR6-TS conditioners cleaned up the AC. As you might expect from such small speakers using two full-range drivers, the stereo imaging from this system was superbly stable and exquisitely well-defined, though double basses did sounded more like cellos, there only being so much low-frequency energy you can extract from 3" drive-units, even when loaded with passive radiators.

Over at T.H.E. Show, Audience were demming the ClairAudient 1+1 bipolar speaker ($1800/pair), which uses two of the small full-range A3S drive-units developed by Roger Sheker, one on the front, one on the back, loaded with two passive radiators on the speaker's sides. The sound was dynamic, with surprisingly extended low frequencies.

The Audio Alternative's big room on the ninth floor was one in which I spent more time than I had intended, such was the spacious sweep of sound produced by the Vandersteen Model 7 speakers ($50,000/pair with premium M7 crossovers) driven by Audio Research Reference 250 monoblock amplifiers ($25,990/pair). A CD of Joe Williams singing a vocal version of Miles Davis's "All Blues," recorded 20 years ago with the then-groundbreaking Colossus digital system kept me in my seat. The source components were supported on one of Harmonic Resolution Systems' excellent racks, BTW.

This bijoux little asynchronous USB DAC ($249), which uses an ESS Sabre DAC and Gordon Rankin's Streamlength code, made its public debut at Newport Beach. It was being demmed in one of retailer Optimal Enchantment's rooms with Audio Research amplification and Vandersteen Treo speakers. Add a PC or Mac, a 1m 3.5mm–dual-RCA Evergreen cable from AudioQuest ($29) and you're in business.

As I was leaving the Venetian after closing up the Stereophile room on the last day of CES, I bumped into AudioQuest's Steve Silberman in the elevator. "I've got one left, take it," he said and handed me the little USB thingie in my photograph. "It's going to cost $49 and will be available in the spring."

Stephen Mejias mention Garth Powell's passion for what he does in his report from the Furman room at CES. AJ Conti, the man behind turntable manufacturer Basis Audio, has a similar passion for what he does. His current attention is focused on getting the drive belts for his well-regarded turntables as flat as possible, to eliminate the last vestige of drive-system spuriae from the audio recovered from vinyl. Dissatisfied with the highest precision he could get from commercial ground-belt vendors, he invested in his own production machinery.

Though I have shown in the photo the prototype of the new BAT P1 phono cartridge, developed by Peter Lederman but with a feature unique to BAT that is said to reduce stylus jitter, the star of this large room was the pair of Scaena line-source speakers ($66,000/system) that were driven by BAT's new Rex tubed amplifier ($15,000, used here bridged for mono) but also proved unphotographable (at least by me). (You can find Jason Serinus' photo of the speaker at the 2010 Axpona here.)

The rest of the system included a Silver Circle Pure Audio 5.0 AC conditioner, Kubula-Sosna Master Reference cables, Critical Mass Systems stands, BAT VK-P10 phono preamp, BAT Rex line stage, Scaena subwoofers, and a Spiral Groove SG-2 turntable and Centroid tonearm. Listening to Marc Cohn's "Riding on a Ghost Train" and Miles Davis's "So What" from LP, it was though I were hearing these familiar pieces for the first time. There was a stability to the high frequencies, a clarity to the midrange, a depth to the low frequencies, that thrilled.

i saw a familiar face when I went into the Veloce room, as Mark Conti, who designed the unusual Impact speakers from a few years back, is now involved in this line of battery-powered amplification. My eyes were attracted by the Veloce Platino LFT-1 linestage in the photo ($12,500), which will run for 70 hours before needing recharging, but driving the Marten speakers in the room via Purist cables was a pair of battery-power monoblocks ($12,000/pair). Battery power? Yes, the input stage, based on a 6922 tube, is transformer-coupled to a high-efficiency class-D output stage based on the Hypex module designed by famed Dutch engineer Bruno Putzys. A charge will last 40–80 hours depending on the speaker's load impedance, Mark told me.

With Benchmark's high-value DAC1 D/A headphone amplifier getting a little long in the tooth—our original review was in July 2003—it was good to hear the new DAC2 HGC ($1995) at Axpona. The DAC2 uses an asynchronous USB2.0 interface, will decode DSD files, has five digital inputs, two single-ended analog inputs, balanced and singled-ended analog outputs, two headphone outputs, and features a hybrid analog/32-bit digital volume control that preserves resolution. Analog signals are never digitized; digital signals never pass through an analog potentiometer; yet both analog and digital volume are controlled with a single knob.

As with past HI-FI Shows, we asked visitors to HI-FI '98 to vote for the room that offered what they thought to be the best sound. The ballot in the Show Guide asked visitors to list the best, second-best, third-best, and worst sounds, for which I allocated 3 points, 2 points, 1 point, and -1 point, respectively. Any exhibitor that received more than 0.7% of the total votes cast is listed in the Table. I've tried to include both the exhibitors and the brands demonstrated, as listed in the Show Guide and in our report text in the September issue of the paper Stereophile. My apologies if I've left anyone out.
