RMAF 2007

I really enjoyed the mellow sound created by the USB-input Benchmark DAC 1 and the Studio Electric T3 loudspeakers. The speaker, with its 87dB sensitivity and 4 ohm impedance, is distinguished by the 6.5" broad-band drive-unit, encased in a stainless-steel sphere, that handles frequencies from 50Hz to 4kHz. Although you can see the diminutive silk-dome tweeter in the photo, the side-firing 8" woofer, which handles the single octave from 25–50Hz, is missing from view. Very, very nice.

I was utterly intrigued by the innovative speakers from Dr. Shelley Katz’s UK-based Podium Sound ($5995/pair). Katz produces panel loudspeakers that mechanically vibrate via electromagnetic drivers. Inherently free from phase error and less sensitive to placement than electrostats, they operate full-range without any filters.

Garth Leerer sure knows how to make a vocal lover happy. As soon as he spotted me entering the Musical Surroundings room, the Oakland-based distributor chose to demonstrate the supreme musicality of the Musical Surroundings’ "Audio Unlimited" system by playing an LP of mezzo-soprano Janet Baker. Recorded in her prime, and sensitively accompanied on piano by the great Gerald Moore, Baker began singing a grief-stricken Schubert song. To say I was blown away by the intensity of her expression, the beauty of her voice, her daring to sing with such naked emotion, and the system's ability to capture and integrate all the different colors and shadings of her instrument only begins to tell the tale. I was transfixed.

Mark Schifter and Walter Liederman of AV123 continue to blow my mind. To their astoundingly low-priced line of quality loudspeakers, only available through the AV123 website, they have added two large loudspeakers from GR Research. Designed by Danny Richie, who previously designed the Epiphany Loudspeakers and is now redoing the crossovers in the Ushers—I am told that Wes Phillips will be reviewing one of Danny’s Usher make-overs for Stereophile—Danny is shown standing next to the GR Research LS6. Priced at $4500/pair, the speakers feature eight 6.5” woofers and six planar magnetic drivers. The LS6 not only boasts a 20Hz–20kHz frequency response, but also features bass drivers that are adjustable according to what the room and system can handle.

"How often do you hear no limiting, no compression, no mixing, and no equalization? Recorded in DSD and played back the same way today" announced the blurb for Ray Kimber's IsoMike dem at RMAF. Inrigued, I entered the ginormous Ballroom F to be confronted by a system costing no less than $507,288! The six pairs of humongous Sound Lab ProStat 922 electrostats were joined by two pairs of a prototype speaker from Sony in Japan, all driven by no fewer than 8 Pass Labs X350.5 monoblocks. Source was Ray's latest four-channel DSD master files stored on a Genex hard-disk recorder and decoded by EMM Labs DACs. Kable was all-Kimber, of course.

I experienced a fascinating comparison in one of the RMAF rooms featuring systems from Colorado dealer ListenUp. With Sonus Faber Cremona Elipsa speakers (review forthcoming) driven by a combination of Musical Fidelity X-T100 integrated amplifier "supercharged" with MF's 550K monoblocks, and Shunyata AC conditioning and power cables, CDs played back on MF's new top-loading CD player were being compared with lossless-encoded files of the same recordings played back over WiFi via a Sonos ZP80 that fed its S/PDIF digital output to the MF player's DAC section. The data were the same, so other than the WiFi connection, there was no reason for the sound to be different. And I did indeed find it very difficult to hear any consistent difference between the two presentations. Perhaps the low frequencies were a little better-defined and extended via CD, but I don't think I could have identified that without knowing which was which. Interesting.

Undoubtedly contributing to the excellent sound I heard from the Vivid speakers in the previous story was this neat 30Wpc class-A integrated amplifier, the L-590A II ($9000) from legendary Japanese brand Luxman, shown here sitting on the top of the stack of Weiss gear. On A Higher Note is now distributing Luxman in the US.
