Maybe it's my selective perception, but there seems to be a resurgence of single-driver speakers. The Gemme Audio Vivace ($4100) uses a 4" Fostex driver in a complex horn-loaded enclosure. Sensitivity is 92dB, which is not high by horn standards, but the claimed bass frequency extension is 20Hz, which is extremely low by any standard. They played some organ music at the demo, and I can't say that I heard anything close to 20Hz. The bass was impressive by single-small-driver standards, however, and the speakers had the coherence that this sort of design is known for. Gemme Audio is a small company based in Montreal, with only two products: the Vivace and the Tanto ($5100), a more conventional two-way system. Getting into the crowded audio marketplace is a difficult feat for any speaker company that doesn't have a full product range; the fact that Gemme has been picked up by distributors in the USA, the United Kingdom, France, Sweden, and Ukraine tells me that they must be doing something right.

Red Wine Audio is the name of the company making amplifiers designed by one Vinnie Rossi, "an electrical engineer with a true passion for music and implementing the electronics that recreate it," whose name, if you pretend that Vinnie is spelled with one "n," means "red wine" in Italian. (Actually, "vini rossi" means "red wines," but let's not quibble.) What makes Red Wine Audio amplifiers interesting is that they're all battery-operated. The system being demoed used a pair of the Red Wine Audio Signature 70 monoblocks ($2999/pair), driving single-driver speakers ($2495 MaxHemp or $949 Super 3XRS) from Omega Speaker Systems. The source was a battery-powered computer server, so that the only AC-powered devices in the room were some table lamps. I can't say whether it was the battery power source or some other aspect of these designs, but the sound was uncommonly natural and easy-on-the-ears. The small Super 3XRS speaker, which uses a proprietary 4.5" Omega hemp-cone driver, had a coherence and focus that reminded me in some ways of the $7000/pair Fujitsu Ten Eclipse TD-712z single-driver speaker that I reviewed in the January, 2007 issue. Shown here are Vinnie Rossi (left) with Omega Speaker Systems' designer Louis Chochos and the Red Wine/Omega system.

Dan Wright's career in audio started as a modifier of D/A converters and CD players. Although his company, ModWright instruments, still does digital source component modifications (he says he finds SACD players to be the best candidates for modification), he has also developed his own preamplifiers and phono stage. The latest of Dan's preamps is the LS 36.5 balanced tube line stage ($4995), which uses his own custom-designed MWI capacitors, 6H30 Russian Super Tubes, and a 5AR4 tube-rectified power supply. He also introduced the new SWP 9.0 SE phono stage at FSI.

Eli and Ofra Gershman of Gershman Acoustics have been exhibitors at just about every audio/home theater show that I've been to in the last few years. They always manage to have good sound, but it's been a while since they've had a new product. They had one this time: the Sonogram ($2500, shown in photo) has a conventional box shape that's unlike their exotic-looking Black Swan, Gap 828, and Avant Garde models. However, I'm told that while the outside appears conventional, appearances can be deceiving, in that the internal structure resembles the pyramid shape that characterizes their higher-priced models. I quite enjoyed the sound of the Sonograms, driven by Linar amplifier and Simaudio CD player.
