RMAF 2007

In a room tuned with the amazing Acoustic System Acoustic Resonators to sound good with the glass window exposed, Darren and Bonnie Censullo of Avatar Acoustics displayed a system distinguished by the kind of openness and air that some people would kill for. Products included the Abbington Music Research AMR CD-77 and AMR AM-77 ($8500 each, both outfitted with NOS tubes), Acoustic System Tango Speaker ($13,500/pair), Current Cable Powercord and interconnects, and a host of Acoustic Resonators. If you look closely, you may see one of the diminutive resonators ($200–$2200) on the rear window. This is one system I hope to revisit if time allows. I’d love to hear some of these products in my own listening room, which is far bigger than the hotel suites into which most systems were shoeboxed.

Walking to the Kimber dem, I heard the familiar sounds of the Beatles' "Come Together" coming from the open door of the Usher room. I had to go in. A pair of the Taiwanese manufacturer's Dancer Be-718 two-ways ($2795/pair) was playing the song, fed by the LP release of Love on an Oracle tonearm/turntable fitted with a Zyx Atmos cartridge, which in turn was feeding the Oracle Temple phono stage, Oracle DAC 1000 preamp, and Usher's R.15 amplifiers. Cabling was all JPS Aluminata. Considering the large room, the relatively small Dancers appeared to have no problem filling it with sound. This is a speaker that deserves review coverage in Stereophile, I feel.

Nelson Pass is up to good again. Following the wonderful sound of Ella and Billy I heard in the corridor, I discovered Nelson's prototype open-baffle speaker system. It sports both a Lowther PM6A full-range driver and a pair of SEAS W26 10" woofers. The 40"-high open baffle, which at this stage of the game is not intended to be a final design statement, has no side panels, only a central brace in the rear. The system was bi-amped, with the Lowther driver fed using a 60Hz, 6dB/octave high-pass filter feeding a First Watt F3 7Wpc JFET amplifier. The woofers were driven by a Pass Labs XA30.5 fed by a 12dB/octave active crossover. No equalization was employed. That the sound was so good was especially amazing, considering that the digital front end was pieced together at the last minute after the originally intended computer drive arrived minus its charger chord. I look forward to hearing the finished product.
