LATEST ADDITIONS

After several years of collaboration with Lew Johnson and Bill Conrad with McCormack Audio, Steve McCormack went it alone a year or so back with SMc Audio. He was demming SMc's first product at RMAF, the $6800 VRE-1 line preamplifier ("VRE" stands for "Virtual Reality Engine"). The solid-state design uses Lundahl and Jensen coupling transformers and uses J-FETs in a zero-feedback circuit. Unusually, it dispenses with the otherwise ubiquitous solid-state voltage regulators in its power supply. Instead, it uses a choke-smoothed voltage rails, which Steve feels eliminates any trace of "transistor" sound. Next to come will be a matching phono stage.

The penultimate room I went into on the RMAF's final day was being shared by SMc Audio and Audience. I was assuming the latter company was demonstrating its well-reviewed AC conditioner and cables, which indeed it was. But I was not expecting to see and hear <I>loudspeakers</I> from the Californian company. The ClairAudient LSA 16 (LSA for "Line Source Array) was designed by the late Richard Smith, cofounder of Audience, and features 4, 8, 16, 24, or 32 50mm drive-units, used full-range, with no tweeters or crossover (something I have not seen since the Ted Jordan designs of the late 1970s). A separate subwoofer handles the low bass and with a very high claimed sensitivity, the ClairAudient design will produce very high spls in-room, but with great clarity. The sound of the 16-driver version in the RMAF room was a little lacking in top-octave air, but was otherwise very detailed. The rest of the system comprised a McCormack Audio UDP-1 universal player, McCormack monoblock power amps, and a preproduction example of Steve McCormack's new SMc VRE-1 line preamp.

We might have neighbors&mdash;and they could be closer than we thought.

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.

The NSR Sonic Research D3 Concerto Sonata loudspeaker ($4495/pair) was reportedly making a lot of waves at its world premiere. Displayed in not completely broken-in prototype form, with tweaking of crossover and capacitors still to come, the speaker is claimed to have 93.7dB sensitivity. The bottom of the enclosure features an exclusive "Acoustic Projection Lens." The lens, developed over the course of 30 years by its guitarist/luthier/locomotive engineer designer, is claimed to act as a sonic prism that overcomes randomly generated frequencies. The company also offers the much larger D1 Concerto Reference ($32,000/pair). Both speakers have back panels that intentionally resonate like an instrument, a feature that JA points out was first seen in the controversial B&#246;sendorfer loudspeakers.

When I entered the room assembled by Matrix Systems of Pennsylvania, Joe of Critical Mass (maker of excellent, hand-crafted supports for amplifiers and other components) was playing a recording of jazz vocalist Mary Stallings (Maxx Jazz). I was immediately captivated, both by the sound, and by Stallings' artistry. When Joe recognized me and asked me if I wanted to play some of my own music, "No way!" I exclaimed. "Let the music continue."

I have commented in previous blogs on the easy, unforced and natural sound of Moscode hybrid electronics. Here, the Moscode 402 200Wpc hybrid amplifier was paired with Quad 988 electrostatic speakers that were bolted to custom bases, Esoteric DV-50 universal player, and Cardas Golden Reference cables. Since neither George Kaye nor Gage Rommel was in the room at the time, I was unable to determine what tubes were being used in the amp. But the ability to easily roll tubes in this unit makes it a dream for people like myself who love to tailor the system's sound to their specific preferences.
