Zu Audio goes its own way when it comes to speaker design goals, emphasizing sensitivity and dynamic range. The Utah company's new Essence ($5000/pair) covers almost the entire audioband with a single 10" drive-unit, augmenting this unit's output from the central "whizzer cone" in the top octave with a ribbon supertweeter. Sensitivity is claimed to be in the high 90s! The enclosure is constructed from Baltic birch ply with an outer MDF cladding, and the internal wiring is, of course, Zu's own cable, with cold-forged, solder-less connections to the Cardas binding posts.

The original Coltrane speaker from Swedish company Mrten Design got the thumbs-up from Michael Fremer when he <A HREF="http://www.stereophile.com/floorloudspeakers/205marten/">reviewed it</A> three years ago, so I was not surprised to hear good sound in importer EAR USA's room from the new Coltrane Soprano ($45,000/pair). The Soprano combines a diamond tweeter from Jantzen Audio said to have a 55kHz bandwidth, with two 7" ceramic-cone woofers from Accuton. Other than the 56mm-thick front baffle, the stylin' gracefully curved enclosure is fabricated from carbon-fiber laminate.

Although Mikey Fremer has received a pair for review, I haven't visited his Jersey crib yet to take a listen. So the system in Boulder's room at CES was my first chance to audition Wilson's new MAXX 3. I popped a data disc with some of my hi-rez 24-bit/88.2kHz files in the Boulder 1021 CD player, and a list of the WAV files appeared on the player's screen. The 1021 will play data CDs carrying FLAC, WAV, Vogg Orbis, and MP3 files, and as I found, will decode and play hi-rez files.

I'm sitting here in front of the trusty Toshiba 286 laptop on December 31, 1992, stuck with apparently incurable writer's block; in a couple of hours, we will be taking off <I>en famille</I> for the latest of Larry Archibald's legendary New Year's Eve parties. I wish I had something to write about for this month's "As We See It" essay; I wish...I wish...you know, there are a number of things I really wish for right now, yet I don't believe there is a component out there that can give me what I want.

If I had to pick one amplifier designer as having had the greatest continuing influence on the high-end market, as much as I admire John Curl, Audio Research's <A HREF="http://www.stereophile.com/interviews/894z">Bill Johnson</A>, and Krell's <A HREF="http://www.stereophile.com/interviews/1203dagostino">Dan D'Agostino</A>, the name of <A HREF="http://www.stereophile.com/news/11661">David Hafler</A> inexorably springs to mind. Not because he challenged the very frontiers of hi-fi sound, but because he combined a fertile, creative mind (footnote 1) with a need to bring good sound to as wide an audience as possible, both by making his products relatively inexpensive and by making them available as kits. (The Major Armstrong Foundation apparently agrees with me&#151;they presented David with their "Man of High Fidelity" award at the summer 1988 CES.) It remains to be seen if the Hafler company will continue in this tradition, now that David has sold it to Rockford-Fosgate. But there is no doubt that many audiophiles were first made aware of the possibilities of high-end sound by Hafler products in the late '70s, and by Dynaco in the '60s.

Some reviews take longer to gestate than others. But in the case of Cary's CD 306 SACD Professional Version SACD/CD player, it has taken me literally years to get this review into print. I had visited Cary's impressive facility in North Carolina just before Christmas 2005, when I'd been playing the high-resolution master files of some of my recordings at an event being promoted by Raleigh high-end dealer Audio Advice. Cary's head honcho, <A HREF="http://www.stereophile.com/interviews/399">Dennis Had</A>, had been playing me music on a system featuring his Silver Oak loudspeakers, with the front-end one of the first samples of the original CD 306, playing discs through the two-chassis Cary SLP 05 preamplifier that Art Dudley <A HREF="http://www.stereophile.com/tubepreamps/906cary">ended up reviewing</A> in the September 2006 issue. "Now <I>that's</I> a product I'd like to review!" I enthused, looking inside the CD 306, and I drove back to Brooklyn with a review sample.
