Alta Audio was showing off their Celesta FRM-2 stand-mounted speakers ($15,000/pair) at AXPONA, driving these two-ways with AVA SET monoblock amplifiers ($5000/pair), which use two of Frank Van Alstine's single-ended MOSFET amplifiers in push-pull to obtain 600Wpc into 8 ohms. The source was Frank's laptop feeding data via a 25' USB cable (!!!) to his Mk.5 DAC and FET/Valve CFR tube preamp. Cabling was all by a brand new to me, Anticables.

The Larson 9 speakers ($14,995/pair) in this room were set up firing across the room width, meaning that the one row of listeners had to sit relatively close. Even so, this system, which used Gamut M250i monoblocks ($25,990/pair) and a Gamut D3i dual-mono preamplifier ($8390), all hooked up with Gamut cables, was definitely "room friendly," producing a comfortable sound from an LP cut of Chet Atkins and Mark Knopler playing "There'll be Some Changes Made."

MoFi Distribution's Jonathan Derda was demming the Wharfedale Linton, 3-way stand-mounted speakers ($1498/pair with stands) using a neat little Quad Artera Solus integrated amplifier ($1999), both products making their US debuts at AXPONA. He played me "Sympathy for the Devil" from the Stones' Beggars Banquet album on a MoFi StudioDeck+U player ($1499 with MoFi UltraTracker MM cartridge) and a Tim de Paravicini-designed MoFi StudioPhono preamp ($299) and this relatively inexpensive system had this old geezer rocking.

I was greeted by a familiar sound from shows past when I went into the first MoFi Distribution room on the Renaissance's third floor: a track from the All Star Percussion Ensemble LP that showed off the superb imaging and terrific transient reproduction of the Manger P2 speakers ($18,995/pair; $21,995/pair in the Rio Palisander veneer being demmed). Using a bending-wave transducer to cover everything from the lower midrange upward, supported below 340Hz by an 8" woofer with a carbon-fiber cone, the P2s sounded perhaps a bit too sweet in the top octaves when the percussion cut was followed by Vivaldi's Four Seasons.

The first of the two ELAC rooms I visited featured the Navis ARF-51 powered tower speaker ($4000/pair). This design from Andrew Jones, shown in my photo, features a coaxial tweeter/midrange unit and three woofers. Level controls allow the balance to be optimized—up to ±1dB for the coaxial unit, up to ±4dB for the woofers.

The smallest model in ELAC's Carina series, the BS243.4 ($1200/pair) represents a departure from Andrew Jones' other designs that feature a concentric tweeter/midrange driver in that it combines a folded ribbon HF unit with a 5.25" aluminum-cone woofer. A reflex design, its port fires downward from the bottom of the enclosure with a slot formed between the base and a plate underneath it. This should make the speaker easier to place in a room where it can't be used well away from the wall behind it.

"What the heck?" Behind the Master Class Area was a giant tan-colored hooded construction, looking like a giant Zamboni machine and labeled "Wynn Audio," with a viewing window at the front.

Getting ready for the first day's visitors in AXPONA's Ear Gear Expo, Ayre's vice president and CTO, Ariel Brown, was busy setting up the Colorado's company's QX-5 Twenty D/A processor ($8950, right) Codex D/A headphone amplifier ($1795, hidden in center, and the new QX-8 D/A processor ($4450 with S/PDIF inputs, $4950 with asynchronous USB input, $5450 with USB and Roon Ready Ethernet, left).

Celebrating 21 years of affordable Music Hall turntables, the irascible Roy Hall (right) was in fine form on AXPONA's opening day, offering show specials.

On my way to AXPONA's Master Class Theater to catch Rob Robinson's seminar on current-mode phono preamplifiers, I was buttonholed by David Janszen. The Janszen name is synonymous with electrostatic drive-units—the midrange unit in the legendary Wilson WAMM was based on Janszen technology—and at AXPONA David was demonstrating prototype electrostatic headphones, the Lotus.
