CES Unveiled turned out to have little of interest to Stereophile readers—except those who are general technical geeks. (Not that there’s anything wrong with that!) Most of the products on display involved mobile computing, computer peripherals, etc., and the exhibits were simple table-top setups. Major CES exhibitors like Sony and Panasonic were conspicuous by their absence. Samsung just had some of their small digicams. I guess the high performance audio community decided to pass on this event, and it makes sense: what makes these products special can’t be evaluated by just looking at them.

The female staff members of Salon Son & Image are easily recognizable by the blue wigs they wear. I don't know whose idea this represents—Michel Plante or Sarah Tremblay would be my guess—but it's a great way of signalling that the show is going to be FUN. The charming Claudia L'Ecuyer (pictured) prepared my badge. In the background, getting his badge is Jim Griffin of Griffin Audio, Canadian distributor of ProAc loudspeakers.

The "Swiss Army Knife" metaphor has been applied to many audio products, but the metaphor has never been more apt than referring to the new Cocktail Audio X30 ($1899). Made in Korea and imported to North America by Audio Plus/Plurison, the X30 is described as an "all-in-one HD music server/network streamer/CD storage." However, that doesn't describe all of its capabilities. If you look at the connections in the back (bottom of the picture), you'll see speaker connections, so it's also an amplifier. (I'm not sure, but I think the number in the model designation indicates the watts per channel.)

Performing music in a group is all about collaboration and communication. Look closely at this picture of the John Atkinson Trio, in performance on the last day of HE2007. JA is playing a solo, and both pianist Bob Reina and drummer Allen Perkins are listening and watching intently. In his comments after the number, Bob said that they had some differences of opinion about how to end the number, and resolving these differences required some give-and-take in the actual playing. Now that's jazz!

The Computer Audio 2010 seminar on Saturday was very well-attended—I barely managed to get a seat. The presentation was by Steve Silberman of Ayre Acoustics, with technical commentary by John Atkinson. Silberman took an admirably generic and non-partisan approach, barely mentioning Ayre products, and refusing to answer the question "Should I get a Mac or a PC?" I've taken a wait-and-see approach to the whole computer audio subject, and Silberman did not convince me it's time to introduce a computer into my audio system, but I must say that he did an excellent job of describing the options, and if I were to take the plunge I would certainly use the information on the Ayre web site.

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.
