Ah, Brazil...land of coffee, the samba, Pelé, Rio-by-the-sea-o, and tube amplifiers. All right, so perhaps the amplifier connection isn't quite as well-established. But one Brazilian amplifier designer, Eduardo de Lima, has published articles in Glass Audio magazine that are viewed by many as groundbreaking, and his evolving products have been seen at various specialist tube equipment shows. De Lima—president, founder, product designer, and principal owner of Audiopax Sistemas Eletroacusticos—is an electrical engineer who started out designing equipment for a telecommunications company, but since 1995 he's devoted his talents to designing a wide range of audio products, including speakers as well as preamps and power amps.

Aurum Acoustics is one of the Canadian audio success stories. Located in Newfoundland, well away from the Toronto-Montreal technology axis, they've succeeded in breaking into the heady world of ultra-high-end audio with an unusual product: an integrated CD player/amplifier/loudspeaker combination. The price is $32,000, with extras like an isolation rack, special power cables, etc., adding another $4k or so. It's a "turnkey" system, and it works. Designer Derrick Moss has to be given a lot of credit for creating the synergy among the different components of the Aurum Acoustics system. In true audiophile fashion, he continues to tweak the system; the most recent tweaks were some internal changes in the mid/high amplifier, and the use of Crystal Cable for internal wiring. The system at FSI sounded great, particularly when playing Ray Charles' version of "Over the Rainbow."

A compact horn loudspeaker. Isn't that an oxymoron, like jumbo shrimp, or military intelligence? From such venerable speakers as the half century-old Altec Voice of the Theater and the Klipschorn, as well as more modern examples like the Avantgarde Acoustic Trio, horns have always been big. The original Avantgarde Uno was the smallest speaker in Avantgarde's line, but it was still visually imposing, with a big horn midrange on top, a horn tweeter below that, and a powered sealed-box subwoofer at the bottom. (I reviewed the Uno 2.0 in Stereophile in August 2000, Vol.23 No.8, and the Uno 3.0 in August 2002, Vol.25 No.8.) The Uno and its siblings, the Duo and Trio, are perhaps the antithesis of the in-wall loudspeakers beloved by interior designers. These speakers do not fade into the background—not visually or sonically.

The warm-up phenomenon—where a system sounds better after it's been on for some time, the time being much longer than would be accounted for by anything in the measured performance—is well-known to audiophiles, and it often manifests itself at shows. This was the case with the system in the Avantgarde room: Avantgarde Duo Mezzo loudspeakers ($47,250/pair), Avantgarde One preamp ($37,500) and One power amp ($45,000), with Brinkmann analog and Audio Aero digital front ends. I heard the system early on the first day of the show, and although it didn't sound bad, it didn't sound as great as I'd heard Avantgarde speakers sounding. Could it be the room or perhaps the setup? Avantgarde Acoustics designer Matthias Ruff was on hand; between him and Jody Hickson of Globe Marketing, Avantgarde's new North American distributor, they should have been able to sort out the setup, but the sound was definitely disappointing, being on the dry side, a characteristic I don't associate with Avantgarde speakers.
