RMAF 2013

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.

"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.

These nice-looking standmounts are Salk Sound's Exoticas ($6000/pair), which use new high-performance drive-units from SEAS. Driven by an AVA solid-state amp (bottom in the rack), they produced a natural sound on a Kimber IsoMike cello recording. But when I first entered this room, the less-expensive, floorstanding Salk Sound Towers, which sell for less than $2000/pair, were producing a big sound on a Trentemoller track, driven by AVA's Ultravalve tube amplifier ($1995, above the solid-state amp in the rack), which gets 35Wpc from a pair of EL34s per channel. Preamplifier was AVA's new FET-Valve CF.

Colorado Springs-based HiFi Imports were demming their system in one of the Marriott's very large ground-floor rooms. Speakers were the Venture Grand Ultimate Mk.IIs from Belgium ($98,000/pair), which combine Venture's proprietary 2" tweeter, which uses a graphite-pulp-composite diaphragm, with a 7" midrange unit and four 7" woofers. All the lower-frequency drivers use carbon-fiber/graphite-composite cones and the speaker's frequency range is specified as 22Hz–60kHz with a 92dB sensitivity.

Denver retailer Gold Sound was featuring Focal's new tower speaker, the Aria 948 ($5000/pair), in its room at RMAF, in a system featuring a Cambridge Audio 851E preamp ($1799) and Cambridge 851W 200–350Wpc amplifier ($2499), both also new at the show. Front ends were either a Cambridge 851C CD player or a VPI Classic turntable fitted with the 3D-printed tonearm and an Ortofon Cadenza Bronze MC cartridge and amplified with a Parasound Halo JC3 phono preamp.

In German Physiks’ room on the 11th floor of the Denver Tech Center Marriott, the Unlimited Mk.II loudspeakers ($13,500/pair) were mated with Vitus Audio’s RCD-100 CD player ($12,750), RD-100 D/A converter ($11,250), and RS stereo power amplifier. Held together by Purist Audio Design’s Corvus balanced interconnects ($2100/1m pair), fabulously named Aqueous Aureus digital cable ($705/1m), and Venustas speaker cable ($5450/7m pair), the system displayed a lovely midrange with a bit of hard edge on a golden oldie, Sara K’s “If I Could Sing the Blues.” (Who remembers the audio show where this track was playing in at least 7 rooms, if not more?) Regardless, I found the superb sense of depth and air uncanny.

Walter Liederman’s Underwood Hifi showed an $11,600 system that he sells for the discount price of $8995 + freight. At its head were Emerald Physics CS3 Mk.2 open-baffle, controlled-dispersion loudspeakers complete with Emerald DSP2.4 digital equalizer/crossover ($3500/pair). Supporting them were two REL T9 powered subwoofers ($1200/each) electronically bi-amped through the Emerald DSP2.4, an Emerald Physics EP100.2SE amplifier ($2200), one DSPeaker Anti-Mode 2.0 Dual Core for preamplification and room correction ($1200), and a Jolida Fusion tube DAC/Transport ($2300). Also included, prices not supplied, were a Pro-Ject Xtension 10 turntable, PS Audio NuWave phono stage, and Mac mini.
