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.

For anyone who's been around the audiophile block a few times, Conrad-Johnson Design is a brand that needs no introduction. My first acquaintance with Conrad-Johnson was before I began writing for Stereophile (more than two decades ago—time sure flies fast when you're having fun!). I was in the market for a new preamp, having become convinced that my Dayton Wright SPS Mk.II was the weak link in my system, and had narrowed my choices to two similarly priced products: a solid-state model made by PS Audio (I'm not sure of the model number), and the tubed Conrad-Johnson PV-2ar. They were carried by different dealers, who allowed me to take their preamps home over the same weekend for a direct comparison. I was impressed by both preamps, and was sure that either would represent an improvement over the Dayton Wright, but in the end decided to go for the PV-2ar. I later traded it in on a dealer's demo unit of another Conrad-Johnson preamp, the PV-5. And, as it turned out, one of my first reviews for Stereophile was of Conrad-Johnson's PV-11 preamp.

I must admit that, for a long time, I found it difficult to accept the idea that a major portion of one's audio budget should be spent on the preamplifier. Speakers, yes—they produce the sound; amps drive the speakers, so they're important. And source components? Well, everyone knows it's garbage in/garbage out. But a preamp? Even the name suggests something that's not quite the real thing, like pre-school, pre-med, or premature. Unlike amplifiers, they don't have to contend with loads that sometimes approach a short circuit, and heat dissipation is not normally a problem. What's the big deal?

Another room that made no claim to being anywhere close to "entry level," featured the ultra-expensive Constellation electronics (Virgo preamplifier, $27,500, Centaur monoblocks, $54,000/pair, and Cygnus Media Player, $29,000). The speakers were the Magico S5s; at $29,500/pair, these are below the median of the Magico price range. The sound was admittedly lovely. Pictured (left to right) are Irv Gross of Magico and Peter Madnick of Constellation.

"Are You a Sharpener or a Leveler?" was the title of my "As We See It" in the February 2009 issue. The terms sharpening and leveling come from work in the field of perception by the early Gestalt psychologists, sharpening referring to the exaggeration of perceived differences, leveling to the minimization of those differences.

Montreal dealer Coup de Foudre's Wilson/Dan D'Agostino room had Wilson's new Sasha II speakers ($29,900/pair), combined with Dan D'Agostino's Momentum Line stage preamp and stereo power amp ($32,000 and $29,000, respectively). The sound was truly excellent.

Walking the halls of the Venetian, you often hear music emanating from the rooms, the sound prompting you either to want to check it out or to walk on by. I was attracted by the music coming from the room identified as Crystal: a clear, lively sound that could be appropriately described as "crystalline." I assumed that the exhibitor was Crystal Cable, which I knew to make some excellent speakers, but which have prices above my CES report coverage limit of $10k/pair. Nevertheless, I went into the Crystal room to have a closer listen—and discovered that the exhibitor was not Crystal Cable, but a company called Crystal Acoustics, based in Greece.

A CD player that combines the transport from a Sony PlayStation, an output section using rare New Old Stock tubes, and no remote control? That’s the DynaStation II CD player ($6000), said to have a cult following in Germany, and now imported by Avatar Acoustics. You can have it somewhat cheaper if you want less esoteric tubes, or pay more if you want even more esoteric ones. The system with Ascendo System E speakers, using the DynaStation II as the source, sounded really good, though.

This Kim Kristiansen slide illustrates the effectiveness of Dali's SMC/linear drive magnetic system in reducing distortion. I believe the lowest curve shows the distortion levels of this the woofer—built completely in-house—that uses the linear drive magnetic system with SMC.

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.
