Patrick Chu, creator and designer of the $80,000/pair, two-way, Mandarin Supreme loudspeaker, explained that the products’ name is a synthesis of two words: Loimin means "delightful understanding" and Chay means "ateliar or studio." The frequencies from 750Hz upwards are handled by a 1" tweeter loaded with a 19" horn comprised of alternating layers of cherry and oak wood. The bass, which is rated down to 22Hz, is handled by 10" and 12" woofers. This composite was by far the least active speaker material I've come across. Rapping it with my knuckles was like tapping on granite. The woofer enclosure was made of concrete with a cloth covering. I didn't ask about the loudspeaker's weight because I didn't want to know. The nominal impedance is 8 ohms, and the voltage sensitive a very high 92dB. Although I didn't audition any familiar reference recordings, the speaker had a dynamic sonic texture with a midrange emphasis.

Music Hall's Roy Hall can usually be relied on to introduce some high-value components at each CES or HE show, and he didn't disappoint this time, either. The Music Hall Trio is a combination CD player, integrated amplifier (50Wpc), and AM/FM tuner (80 assignable presets, remote controllable). Not bad for $999—and, given Roy's track record, it's pretty certain to sound good, too.

I never know what to expect at the "Ask the Editors" sessions, traditionally moderated by Stereophile editor John Atkinson (above). Sometimes we get a lot of people looking for advice on potential purchases of equipment, questions about arcane aspects of amplifier design, questions about cables, about double-blind testing, where the future of audio lies, and, of course, questions about what we thought of the sound in specific rooms at the Show. This time, many of the questions dealt with, of all things, music! There were opinions expressed about the major symphony orchestras of today vs those of the past, and great performances available on LPs. Don't these people know that we're all supposed to be a bunch of equipment-loving geeks?

"That's an impressive soundstage for a two-way monitor," I thought looking at the diminutive Confidence C1 loudspeaker, but hearing a wide, deep soundstage. Dynaudio's 25 lb pound, two-way ($7000/pair plus $450/pair for two) features a 7" woofer and the Danish company's acclaimed Esotar2, 28mm, soft-dome tweeter. The drivers are mounted on a baffle that is said to be decoupled from the cabinet. Dynamic range was superb driven by Simaudio Moon W-7M monoblocks, thought JA, who thought that this system's reproduction of Stereophile's new Attention Screen CD was one of the best he heard at the Show.

Several of Stereophile's editors were excited about the compact and inexpensive Audioengine 5 amplified speakers ($349/pair), which were bringing forth some sweet sounds playing files directly from a laptop. New to the Audioengine line is the tiny 2 (seen here, $199/pair), which offered a sound surprisingly similar to that of its bigger brother. The music was clean and clear, and conveyed an emotion that belied the speaker's size. Like the A5, the A2 keeps all of its electronics in the left speaker but, unlike the A5, it uses a front slot port for bass performance.

Todd Eichenbaum, design engineer at Krell, walked me through the design of their new amplifier, the $10,500, 300Wpc 302. The power supply employs a 3kVA toroidal transformer, built-in power conditioning, a current-mirror input stage, a push-pull driver stage, and low negative feedback (8dB) around the output stage. It was paired with the $10,000 Evolution 222 stereo preamplifier.

Well, few people have. In a stunning collaborative effort, Rives Audio, RPG, Modex, Talon, VAC, Wadia, XLO, and Silent Running set up two rooms designed to demonstrate that even the best audio components need a little help from intelligently applied digital EQ and room treatment. Two rooms, almost mirror images of one another, with essentially the same system—only one room used EQ and treatment and the other didn't. Here's the system rundown: Wadia 581i disc player ($9450), 100Wpc VAC Alpha integrated amplifier ($10,000), Talon Thunderhawk loudspeakers ($25,000/pair), XLO Signature 2 interconnects ($00/m). XLO Signature 2 speaker cable ($2700/2m), XLO Argentum XP3 power conditioner ($600), and Silent Running Craz Reference isoRACK ($6000, as configured here).

As you can see from Larry Greenhill's photo, Chord's RED Reference CD player ($28,500) is one sexy piece of kit. The gleaming metalwork, the sturdy clamshell clamp, its swooping lines—it's just gizmoidally drool-worthy.

I tried to get an arty shot of Bob Reina playing the Steinway. His chromaticism and inspired soloing made me aspire to a higher level of craft.

Peak Consult's Per Kristoffersen poses with his new floorstanding two-way Princess loudspeaker ($10,500/pair). "You know," he said, "it is really quite amazing what you can get out of a 5.5" driver."

Late Sunday afternoon, with only about an hour left before the show closed, it was still standing room only in the Music Hall room. Perhaps that had something to do with the choice of music. I walked in to be greeted by the naughty sounds of the Bear Family Records compilation, Eat to the Beat: the dirtiest of them dirty blues, featuring song titles I can't even mention here.

Masataka Tsuda designs and manufactures both Concert Fidelity and Silicon Arts components. What's the diff? Concert Fidelity is his tube line; Silicon Arts Design represents his thinking on—you guessed it—solid-state.

The Audioengine team is also looking at alternative cabinet materials. On display was a prototype A5 housed in lovely, sustainable bamboo. While the electronics remain the same, the bamboo models will incorporate added dampening.

Krell Industries' new Modulare Duo loudspeaker system was the one active exhibit in their suite, playing music from an excellent sampler of audiophile favorites. Todd Eichenbaum, shown standing next to the $35,000/pair, 300 lb system, explained that the separate woofer and satellite units were made of machined billet aluminum, as with Krell's original LAT-1 speaker system, but the Modulare’s drivers and passive crossover circuitry have been designed for higher current handling. The low-frequency cabinet contains three 8" aluminum-cone woofers, while the satellite section marries a 1" ScanSpeak ring-radiator tweeter, and a 6.5" aluminum-cone midrange driver.
