In Room 806, one word said it all: Rega. Demming the Rega RP8 turntable with Rega Exact 2 cartridge ($3400), Rega Apollo R CD player ($1095), Rega Brio R integrated amp with phono stage ($895), and Rega RS3 floor-standing speakers ($1395/pair), the nattily bow-tied Barnaby Fry of The Sound Organisation was having a ball playing Johnny Adams' From the Heart. The system did best on Adams' voice—the voice was great—but when the blues artist sang, "I can't control the vibrations," I'm afraid he was talking about the limitations of the system's bottom reach and bass control. (For starters, I don't believe power conditioning or special equipment supports were in use.) But on voice and piano, Rega x 4 = very nice.

As Halie Loren sang her distinctly un-Peggy Lee version of "Fever," I reflected on how much I love the color and warm of Unison Research electronics. The internal glow of the sound, and the sweetness of the electric keyboard, especially stood out. Yummy.

In the second room sponsored by Arnold Martinez' newly opened Tweak Studio (located in Chicago's Hyatt Downtown) and Colleen Cardas Imports, a SOTA turntable, curiously unidentified on the room's equipment list, and unidentified cartridge and tonearm, were making lovely sound with three products from PureAudio. Designed by Ross Stevens and Gary Morrison, formerly of Plinius, the redundantly titled PureAudio dual-mono vinyl phono preamplifier ($4500) joined PureAudio's dual-mono Control preamplifier ($9500) and Reference 65Wpc class-A monoblock amplifiers ($15,500) to drive My Audio Design 1920S loudspeakers ($3800/pair).

I first heard the dipole Orion 4 speakers ($14,750/pair with Analog Signal Processor), designed by Siegfried Linkwitz and manufactured by Wood Artistry of Healdsburg, California, at the 2011 AXPONA in Atlanta, where they were one of the best-sounding rooms at the Show. They were in too large a room in Chicago, but still managed to sound clean and natural, with a full range of frequencies, driven by Pass Labs amplification with DH Labs cabling. I refer you to me 2011 report for details on the speaker's design but new at Chicago was a refined version of the Analog Signal Processor, with closer-tolerance crossover components, and an amplifier/processor that obviates the need to drive the Orions with 6 or 8 amplifier channels and the resulting confusion of cables.

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'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.

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.

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.

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.
