Don Keele's Circular-Arc Speakers

The Chicago Show was my second opportunity to hear the unique circular-arc line array speakers designed by legendary audio engineer Don Keele, who was for many years the speaker reviewer at the long-gone Audio magazine. The 5'-tall CBT36 covers a 36° vertical arc, and with its 72 ¾" tweeters and 18 3.5" midrange units, all sourced from Dayton, projects a tailored wavefront that both allows for a very wide sweet spot from where a stereo image can be perceived and doesn't fall off with distance in the usual manner. The speakers used a DEQX digital crossover and were being driven by an Acurus amplifier. They were operating down to 45Hz, below which a subwoofer took over.

Peachtree Packs 'Em In

Peachtree's room was typical at AXPONA, packed with an enthusiastic crowd of listeners enjoying the music all weekend. The Peachtree Nova125 that Sam Tellig reviewed in January ($1499) was being demmed with the MartinLogan Montis speakers that Robert Deutsch reviewed in September 2012 ($9995/pair). The speakers were certainly not let down by the inexpensive amplifier—"The Nova125 will handle any source, any speakers," proclaimed Peachtree's Jonathan Derda (below)—who played me Rickie Lee Jones on LP on a Pro-Ject turntable with Phono Box dual-mono phono preamp, the sax-and-bass duet on Sting's "Standing on the Moon, from a Turtle Records hi-rez file, and even a luminous-sounding MP3 streamed from Spotify.

Kyomi–CAT–Verity–Stealth

Verity's US distributor John Quick (right) shows the Amadis speakers, with Brian Wasserman

Back in 2009 I recorded classical pianist George Vatchnadze for a live-vs-recorded dem. As well as being a superb classical pianist and teacher—he teaches piano at Chicago's DePaul University—George has a parallel life as an audio retailer. His company, Kyomi Audio, had two 8th-floor rooms at AXPONA, featuring Verity Amadis speakers ($30,000/pair) driven by CAT amplification and hooked up with the huge and expensive helium-filled Stealth cables. Sources were either an Acoustic Signature turntable fitted with a Funk Firm arm and Colibri cartridge, or an Esoteric transport feeding data to a prototype non-oversampling D/A processor from Stealth, this featuring the AD1865 DAC chip.

The Marten Djangos

In the second Kyomi Audio room, E.A.R. USA's Dan Meinwald was doing an effective dem of the Marten Django XL speakers ($15,000/pair) that Erick Lichte favorably reviewed in September 2012. He used a prototype CAT tube amplifier, a CAT SL1 Renaissance tube preamplifier, and an Esoteric K-1 DAC with standalone clock fed audio data from Amarra. Cabling appeared to be all Magnan. With the Swedish speakers set up firing along the room's diagonal, low-frequency room modes were tamed and vocal music blossomed, whether it was Peggy Lee singing "Fever," Paul McCartney singing a demo of "Mother Nature's Son," or Neil Young live from Massey Hall.

Super Salk

Bob Walters of the Bay Area Audiophile Society often refers to Jim Salk's loudspeakers as one of the best buys in high-end audio. Certainly I have never heard them sound better in a show context. Using an AVA ABX switch ($1499), Salk Audio switched between three of its speakers: Salk Silk Bookshelf ($3499/pair), Salk Supercharged SongTowers ($3495/pair), and, the largest Salk SoundScape 8s ($7995/pair). The 8 uses the same RAAL ribbon tweeter, Accuton midrange, and 12" passive radiators as in the two larger SoundScape models (not shown), albeit with two 8" drivers.

Laufer Teknik Wows

Both at and post-show, Buffer (aka L. Langdon Ergmann, Jr.) was charmingly apologetic. Having read my "As We See It," "There's No Business without Show Business," in the April issue of Stereophile just hours before I walked into his Laufer Teknik room, he knew that his inability to supply a list of components and prices, add a track to his Memory Player from one of my six USB sticks, or even tell me what music was playing on his own music server (as in "We don't have an internet connection, so we can't identify the track") had left him a prime candidate for the Duncecap Dealer of the Day award.

Marantz and Boston Acoustics

There was a lot of major explication going on in the Marantz room, as in you'll hear some music if only you'll entertain our track-punctuating spiel, but when I did hear a bit of Chris Jones on the just introduced Marantz Reference NA 1151 network audio player/DAC ($3500), my interest was piqued by the depth and weight of the sound. Better yet was Sensemayá from the Channel Classics hybrid SACD of music by Revueltas. Here, the new Marantz Reference SA 1153 SACD/CD player ($4000) and Reference PM 1153 integrated amplifier ($5000), feeding Boston Acoustics M350 loudspeakers ($2500/pair), surprised me with their big soundstage and engaging depth. Even if the core sound of the lowest percussion wasn't totally fleshed out, the way the system delivered what highs and lows the speakers (45Hz–30kHz ±3dB) could produce suggests this may be some of the best audio equipment Marantz has yet released.

Excitement from JansZen and exaSound

My first opportunity to hear the exaSound e20 DSD/DXD/PCM DAC ($2500) did not disappoint. The company that self-effacingly identifies itself as "exaSound," with a small "e," played along with surprisingly extended Janszen 2A2.1 electrostatic loudspeakers ($7495/pair),, which are reputedly flat to 40Hz, and the Bryston Power Pac 250 amp ($2350) to deliver a beautiful smooth, wide soundstage on a DSD recording from Channel Classics.

International Phonograph Inc.

I wish I could say something of import about International Phonograph Inc.'s room, which was showcasing the Artisan Fidelity turntable. The marvelous TAD Reference One loudspeakers were mated with Lamm electronics to play master tapes of jazz and other genres. Alas, there was far more talking than music going on when I stopped by, and the promised equipment list never made it to my inbox. Hopefully, others can fill in the blanks in the comments section below.

Anything But Vaporware

Handsome Vapor Audio Cirrus Black loudspeakers ($3995/pair)—I don't have a clue as to why speakers of blond wood are named "black," unless it’s a Harry Potter reference—mated with exotically named Arte Forma Due Volta monoblock amplifiers ($5500/pair) and Thalia preamplifier ($2250), a B.M.C. DAC1 ($5690), Antipodes DV2 music server ($3299), Antipodes Reference speaker cables ($2200/set) and interconnects ($1900), Balanced Power Technologies PC-9LN power cables ($499) and BP-3.5 power conditioner ($2399), and ATS Acoustics room treatments to produce sound that I found nicely illumined, albeit a little hard and unyielding. The system may not have penetrated to the heart of the music, but the sound was very attractive, solid, and well-controlled.
