Concrete Block Amplifiers from Tri-Art Audio

Canadian-designed and assembled, the signal distinguishing feature of Tri-Art Audio amplifiers is that concrete is used extensively in their construction. Tri-Art Audio believes that class-D power amp chips offer superb power but suffer from microphonics, and only when the chip is isolated from vibration can its virtues be truly experienced. The Block amplifiers do just that. The amplifiers are available in various forms, some with and some without level controls, with optional battery power supply, power ranging from 25 to 200Wpc, prices starting at $1995.

Ron Sutherland With His New N1 Preamp

Ron Sutherland of Sutherland Engineering is famous for his phono preamps. At TAVES he introduced a new product: the N1 ($10,000), a line-plus-phono preamplifier. The most striking thing about this product is that it uses Nixie tubes for the display of source number and volume. Nixie tubes are those little tubes that light up to display a number or other characters. It's a charmingly retro look. I didn't think that these tubes are being made any more, and Ron Sutherland confirmed that this is correct; however, he has purchased a huge stock of Nixie tubes, so his customers are taken care of.

Video Display Shoot-Out

It's called Toronto Audio and Video Entertainment Show, but--just between us—TAVES is basically an audio show. This is not for want of trying on the part of show organizers. They've arranged seminars on the TV calibration, the differences between LCD, LED and plasma displays, and set up an elaborate blind comparison involving 20 flat panel displays that included LCD, LED, and plasma designs, all professionally calibrated, and with the brandnames obscured. I thought it was quite an interesting and useful comparison, but on the three occasions that I visited the room, there were hardly any people there—contrast this with the booths where LPs and CDs were being sold (below).

Reev Designs

Reev Designs is a new Toronto-based speaker company, with so far just one model: the large, stand-mounted Aetma ($6950/pair). It's a striking-looking speaker, with wooden extensions on each side that are said to be critical in controlling resonances. Frequency response is claim to extend from 44Hz to 22kHz, ±3dB.

The Zu Omen Def

I know that Zu is a manufacturer of loudspeakers, but what does "Omen Def" mean. I have no idea, but a pair of these speakers was producing a lively sound at TAVES. At $3400/pair ($2900/pair show special), the price seemed eminently reasonable. They were playing vinyl, courtesy of a KLM 15 turntable and Denon 103 Grade 2 (yes, it's still being made) cartridge.

The TTWeights Turntable

Turntables were much in evidence at TAVES. Oracle was here, of course, and another "Made in Canada" line of turntables that I was not familiar with: TTWeights Audio. Located in Newmarket, Ontario, TTWeights have an honest-to-goodness aerospace CNC facility: their website notes that they have just signed a Long Term Agreement to supply the Curtiss-Wright Corporation critical cabin-pressure controls for the Boeing 737 passenger aircraft. This high-tech expertise has been applied to the design and manufacture of turntables. These include the Momentus, Momentus Supreme, and the GEM, which utilize a Duo Drive design: Direct Rim Drive or Tri-Belt. Prices are in the $6000–$15,000 range. This is serious stuff, beautifully made.
