RMAF 2013

"Together, We Make Beautiful Music" proclaimed the one-sheet that was handed to me in this room. "You are listening to a complete audio system that cost under $15,000," it continued, adding that "we put together this relatively modest playback system to better demonstrate the musical purity and refinement produced with products manufactured by: Mojo Audio, Atomic Audio Labs, VH Audio." $15,000 doesn't sound "relatively modest" to me, but the sound in this room was surprisingly good considering that the speakers were a DIY design using a full-range 8" unit and the amplifiers were vintage Allen organ tube models, based on the Williamson circuit.

I went into the SimpliFi room expecting to see the excellent Weiss MAN301 media player and effective DSPeaker room correction and D/A devices. Yes, there were there at RMAF but SimpliFi's Tim Ryan wanted to talk about the Swiss Klangwerk Ella active speaker ($15,000/pair) shown in my photo. This modest-looking floorstander uses DSP to make it work as a time-aligned virtual point source. A constrained layer-damped Corian front baffle supports an advanced Aerogel-dome tweeter from Audax and a 5.5" woofer; two more 5.5" woofers covering the same passband are placed on the speaker's sides, and all three are reflex-loaded with a downward-firing port. The advantage of this design is that it has a wide listening window on both vertical and horizontal planes, explained Tim, and indeed, on Dire Straits' "Brothers in Arms," I found that I could move up and down and from side to side without any significant change in the perceived balance.

At the 2012 RMAF, Ayre Acoustics had decorated their room in the Marriott's tower to resemble a 1950s bachelor pad, complete with lava lamp. This year, the theme was Charlie's Records, complete with racks of bargain LPs offered for sale. It was great to see Ayre founder Charlie Hansen (left, above) back in action at a show, after a long hospitalization. The system featured JBL K2-9800SE speakers driven by Ayre's VX5 power amp and KX5 preamplifier, with source either an Ayre DX5 universal player or an Ayre/Bauer DPS turntable amplified by an Ayre P5 phono preamplifier.

How wonderful to finally catch up with Scott and Paul McGowan, and to discover how good PS Audio’s prototype class-D amplifier with Hypex modules sounds in its temporary housing. Equally exciting was the just-launched NuWave Phono Converter (NPC, $1895), which combines a phono stage with an A/D converter that can archive LPs in both PCM and DSD formats. Paired with Von Schweikert VR-35 loudspeakers ($10,000/pair) and a custom subwoofer, the system delivered impressive deep bass on a track from Turkish artist and DJ Mercan Dede’s Breath, and lots of color on a track by Chesky artist Marta Gomez.

Sergey Sorokin, who deserves kudos as Russia’s first high-end manufacturer, arrived at the Marriott Denver Tech Center from Moscow a day before other exhibitors to ensure that his set-up was as close to ideal as the room allowed. Nonetheless, as John Atkinson and I learned upon listening, one of his Israeli-sourced, hand-wound transformers was damaged in transit, and insisted on humming/buzzing along with the music. Despite the unexpected accompaniment, the voice of Lorraine Hunt Lieberson singing Handel (Avie SACD) exhibited absolutely gorgeous tonalities. The great artist’s hushed sounds, even through the transformer noise, were something special. The period instrument orchestra’s bass foundation was also solid and superbly rendered.

German loudspeaker manufacturer ELAC showed its prototype Air-X403. Scheduled for launch at CES2014, the wireless loudspeaker system includes a passive model ($2800?) and an active baby with a 210Wpc, class-A/B amplifier ($4000 range total). This black, bottom-ported speaker system did a very nice job on a track by Diana Krall, a singer John Atkinson enjoys, and I do in moderation. I would never have expected such a good midrange from such small speakers.

In the room put together by Rutherford Audio of Denver, Genesis’ 7.2f loudspeaker ($12,500/pair), whose servo-controlled bass extends down to 22Hz; Burmester’s 089 CD player ($33,000), Phono 100 ($20,000), and 956 amplifier ($19,000); Thorens’ TD 2035 Black with TP92 Genesis cartridge (price given as $6399 table, priceless cartridge); and Genesis cabling made for an ear-opening combination. An LP of Count Basie and his Orchestra’s “Me and you” had huge dynamic range, a nice and warm midrange, and an aggressive top. My JVC-XRCD of Sarah Vaughan and Basie was a bit mellower, but the top was again bright.
