There were two causes for excitement in Room 1534: the premiere of the Stenheim Alumine Three ($29,900/pair), the Swiss company's newest three-way floorstander, and the return of Einstein Audio to the US. The latter comes courtesy of its new brand ambassador, Walter Swanbon of Fidelis AV. The sound wasn't perfect—it was a little peaky on what may have been an unnaturally bright Deutsche Grammophon LP of Geza Anda playing Mozart's Piano Concerto No.17, but it was still wonderful (and, sadly, the only Mozart I heard at the show). That a totally different, winningly smooth sound came from Intervention Records' reissue of the LP Joe Jackson Live in New York suggests that an LP of someone else playing Mozart's PC No.17 might have been a better choice sonically.

A room sponsored by multiple companies and overseen by Steven Norber of PranaFidelity immediately won me over with its gorgeous midrange. "So beautiful and warm and all-embracing," I wrote in my notes as I listened to a surprisingly good-sounding 1991 CD of David Wilcox on a substitute basic Pioneer Elite player used as a transport. I also loved the sound of an LP that melded the artistry of two greats, Louis Armstrong and Duke Ellington.

"Handcrafted In Germany" it proudly says above AVM's new Rotation R5.3 Cellini Edition belt-drive turntable, with its acrylic Illumine platter softly glowing blue. With its 10" AVM tonearm, the R 2.3 will cost in the region of $8900 and, fitted with an Ortofon Cadenza Black cartridge, did justice to Diana Krall singing "Indeed I Do." (For what it's worth, while many showgoers dismiss Krall as an over-exposed pop singer—I'm looking at you, Jason Victor Serinus— I respect both her musicianship and her piano playing.)

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."

Once again I experienced the mellow core of the Jeff Rowland sound. This time, it was in the room he shared with Joseph Audio and Cardas Audio, where the big news was the premiere of the Joseph Audio Perspective2 Graphene speaker ($14,999/pair). When I entered, a track from a recording I know very well, Rosa Passos and Ron Carter's Entre Amigos, was sounding far more mellow and toned down than on my system. This setup also brought out the mellow core of a sweet violin in the Bruch Scottish Fantasy.

As soon as I entered the second Kyomi Audio room and heard a track from Alice Coltrane and Pharoah Sanders' great recording Journey in Satchidananda, I realized that it had been far too long since I'd had the pleasure of listening to Dan Meinwald's eclectic and thankfully outside-the-norm music selections. Meinwald, a longtime member of our industry who has spent a considerable time working for EAR USA, had paired the EAR Acute Classic CD player ($6795), V12 integrated amplifier ($9795), and, in a world premiere, the company's new Phono Box phono preamp ($1895 in black) with a Merrill-Williams 101.3 turntable ($8995) with Helius Omega Standard tonearm ($3695) and Koetsu Rosewood cartridge ($3495). Speakers were Marten Django L ($10,000/pair) and cabling Magnan Silver and Signature.

Retailer, concert pianist, and pedagogue George Vatchnadze, whose shop Kyomi Audio contributed products to at least five rooms at AXPONA, assembled an impressive system distinguished by a wonderful, warm midrange and excellent bass tonality. On vinyl, which is all I heard, the system's strengths came to the fore in the classic RCA Living Stereo recording by Fritz Reiner and the Chicago Symphony Orchestra of Prokofiev's Lieutenant Kije suite, where the depiction of depth and space was superb. "Soundstaging for days," I wrote in my notes, while also praising the system's midrange. I also loved the warm, smiling midrange core and the ability to hear artificially added reverb on Ella Fitzgerald's recording of "Cry Me a River" from Let No Man Write my Epitaph, and the excellent bass tonality on "Use Me" from the MoFi reissue of Bill Withers' Greatest Hits.

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.
