Swedish manufacturer Sjofn was luring visitors into its room with an attractive woman drawing their attention to a poster on the wall outside the door announcing (the clue). Inside the room was a pair of unprepossessing stand-mounted speakers, driven by a Hegel amplifier via Supra cables. The two-way, ported Sjofn speakers ($999/pair) were taking full advantage of their boundary loading to produce a big sound.

I hope this doesn’t gross you out or make you cancel your subscription or anything, but SEXY (in all caps) is the first word that came to my mind when I walked into the room hosted by Tone Imports, DeVore Fidelity, Well Tempered Labs, and the Box Furniture Co.

There was a lot of pretty stuff to look at and listen to in here.

The Audio Alternative's big room on the ninth floor was one in which I spent more time than I had intended, such was the spacious sweep of sound produced by the Vandersteen Model 7 speakers ($50,000/pair with premium M7 crossovers) driven by Audio Research Reference 250 monoblock amplifiers ($25,990/pair). A CD of Joe Williams singing a vocal version of Miles Davis's "All Blues," recorded 20 years ago with the then-groundbreaking Colossus digital system kept me in my seat. The source components were supported on one of Harmonic Resolution Systems' excellent racks, BTW.

Here's the SACD in its multichannel glory, newly arrived at RMAF!

"Dimensional Purity" is the promoted benefit of Richard Vandersteen's approach to speaker design, and in one of the two rooms I went into at RMAF organized by Fort Collins retailer The Audio Alternative, the Vandersteen Tréos ($5990/pair) were living up to that promise. Driven by an Audio Research Vsi60 integrated amplifier ($4495) with the source the Bryston BDP-1 digital player and BDA-1 DAC, all hooked up with AudioQuest cable, Mark Isham's Blue Sun reproduced with excellent bass extension and clarity and a laidback but detailed midrange.

This was posted on the wall of his RMAF room by one manufacturer who still makes his products in the US. The message seems clear enough, even if it over-simplifies what is actually a complex situation—see my September 2011 "As We See It" on this subject.

A highlight of the 2011 RMAF was the first public demonstrations of James Guthrie's 40th-anniversary surround mix of Pink Floyd's classic Wish You Were Here, hosted by Acoustic Sounds' Chad Kassem (shown in my photo) and James Guthrie. With a system comprising five ATC professional active monitors fed by a Playback Designs SACD player, Showgoers were treated to a complete playback of the album from the SACD, to be released next month.

From the opening sound effects that tracked from the rear to the front, to the final fade on "Shine On You Crazy Diamond Part 9", listeners were immersed in the re-creation of one of the finest rock albums of all time. I felt Guthrie's surround mix was true to the band's original two-channel intentions while expanding the soundfield to take full advantage of the multichannel medium. "Magnificent!" I scrawled in my notebook. The Studio Six SPL meter on my iPhone indicated that the sound pressure reached 106dB—the experience was like being at the highest fidelity rock concert ever!

A quarter century ago, it was de rigeur for show exhibitors to use a Linn Sondek LP12 as the source. The only Linn I have found at RMAF so far was in one of the Audio Alternative rooms, which was using the fully loaded LP12/Ekos SE/Radikal/Urika/Keel LP player/phono stage with a Lyra Kleos cartridge ($23,905). But with Wilson Sasha W/P speakers ($28,900/pair) hooked up to a Rega Osiris integrated amplifier ($8995) with AudioQuest cables, the sound of Dusty Springfield's "Son of a Preacher Man" from the new APO 45rpm pressing of her classic Dusty in Memphis album was vividly real-sounding.

I first encountered DEQX when Kalman Rubinson and I reviewed the NHT Xd speaker system a few years back, which featured its digital signal processing to implement its crossover and response optimization. The Australian company was putting on an impressive dem of its HDP-3 standalone processor at RMAF, showing the sound of a pair of Gallo Reference speakers driven by Parasound Halo amplification could be first optimized in both time and frequency domains, then its interaction with the room. DEQX's Larry Owens, shown in the photo, enthused about an unanticipated benefit of the speaker correction was the reduction in loudspeaker intermodulation distortion.

The Hyperion, Soundsmith’s new top-of-the-line moving-iron phono cartridge, utilizes a cactus needle cantilever. (That’s a cantilever made of a cactus needle.) Inspired by (the always dapper) Frank Schroeder and designed by Peter Ledermann, the Hyperion’s cactus needle cantilever provides both stiffness and damping—qualities which, according to Ledermann, had previously been mutually exclusive.

In my opinion, one of the coolest-looking systems of the show was pieced together by New York City’s Audioarts: Rethm Maarga loudspeakers ($8750/pair), Fi amplification, and a Lector CDP-6 CD player. The sound was just as good as the appearance: immediate and realistic, with a rich, detailed midrange.

It was a pleasure to finally meet Nick and Jennifer Atocha, makers of the most beautiful record cabinets I’ve ever seen. In the imaginary future of my mind, I will live in an old brownstone with extremely high ceilings, wide plank floors, cool chandeliers, a spiral staircase, a grand fireplace, a secret library, sky lighting, and at least three or five (I don’t like even numbers) of Atocha’s record cabinets.

Jennifer very slyly warned me of the possibility—no, inevitability—of my dear Ikea Expedit shelves collapsing beneath the weight of all my precious vinyl. I frowned.

“Do you have children?” she asked.

New from the Norwegian Hegel company at RMAF was the HD11 D/A processor ($1200), which features a 32-bit TI DAC but also a unique impedance-optimizing circuit on one of its coaxial S/PDIF inputs. Single-ended digital audio connections are specified to be 75 ohm transmission lines, explained Hegel's Anders Eitzeid, but not all all datalinks conform to that specification. (The RCA plug is a major source of the impedance mismatch even when the cable itself has a characteristic impedance of 75 ohms.) The impedance mismatch creates reflections that corrupt the integrity of the RF datastream, increasing jitter.

In the BorderPatrol room, we listened to that company’s beautiful-looking S20 300B single-ended power amplifier ($13,500) and EXT1 preamplifier ($12,250), driving a pair of Living Voice Avatar OBX-RW loudspeakers ($10,895/pair).

Similar to the system we enjoyed at the California Audio Show, here we heard the beautiful Sony SS-AR1 loudspeakers ($27,000/pair) with Pass Labs X600.5 power amplifiers and XP-20 preamplifier, Parasound Halo JC3 phono preamp, Clearaudio Concept turntable, and an EMM Labs XDS1 SACD player. Speaker cables were Kimber Kable's KS-3033, interconnects were Kimber's KS-1111, and AC cables were Kimber's PK-10 Gold.

The system sounded rhythmically nimble and certain with big, fleshy images, a rich midrange, and warm, full bass. Easy to listen to and easy to enjoy.
