For far longer than I've been attending the January Consumer Electronics Show (CES), it has overlapped with the AVN Adult Entertainment Expo. Indeed, in the old days when the high-end portion of CES was housed in the Sahara hotel and casino, the two shows shared the same venue, leading to one of the more bizarre culture collisions known to modern man (one was certainly never in doubt as to who was there for which show).

The penultimate night of CES is traditionally the night of the industry party thrown by <I>Stereophile</I> and <I>Home Theater</I> magazines&mdash;the 2007 CES saw the event taking place at Le Cirque club at the Paris Hotel. The good and great in high-end audio can be seen in the photograph and while we will not be giving points for identifying guests, we will kick the game off by pointing to Arcam founder John Dawson, in the white shirt ordering drinks from the bar at the top left. (A larger version of the photograph is posted in our <A HREF="http://forum.stereophile.com/photopost/showphoto.php/photo/1073">website photo gallery</A>.)

The unquestionable sonic high point of my second day at CES was the opportunity to hear two of the larger, floorstanding speakers in the line that has already brought us the much-touted $20,000/pair Magico Mini "bookshelf." The largest and most expensive of the pair is the $120,000/pair M6 (Model 6). First released one year ago, this four-way floorstander includes three 10" woofers, one 7" mid-bass driver, one 5" midrange unit, and an air motion-transformer tweeter. Weighing 650 lbs, with an enclosure of extruded aluminum, the speaker is said to extend from 28Hz to 50kHz, with a 90dB sensitivity and a 4 ohm impedance. The M6 recently won the Grand Prix Award from Japanese magazine <I>Stereo Sound</I>, and was featured on the cover of its December 2006 issue.

Canadian speaker company PSB has majored in high-performance affordable speakers, with its tiny <A HREF="http://www.stereophile.com/standloudspeakers/792psb">Alpha</A&gt;, introduced in 1992, becoming on of the best-selling speakers of all time. Designer Paul Barton (above), however, has been working on a flagship PSB speaker, which he demmed at the Lenbrook suite at the Hard Rock Hotel. Yet to be named, the new speaker will cost a still-affordable $4500/pair and spearheads a new line of six models to be introduced in the second quarter this year.

Covering a Show as large and as geographically diffuse as the CES invariably leads to moments of writer brainfade. I auditioned Sonus Faber's new Elipsa loudspeaker in the Sumiko suite at the Venetian on Tuesday evening just before the Show closed but had run out of space on my camera's memory card. Back in my hotel room Thursday evening, after the Show had closed until January 2008, I found my note to myself on my PDA reminding me that I needed to take the Elipsa's photo for this report. So words will have to suffice, I am afraid, as well as a link to Sonus Faber's <A HREF="http://www.sonusfaber.com/index_altri.html">website</A&gt;.

You'd think there was not much more to say when it came to horn speaker design. Yet there, in one of the Venetian's 29th-floor rooms was audible proof that progress can still be made. Designed by Japanese engineer Tetsuo Kubo (above), the <A HREF="http://www.kubotek.com">Kubotek</A&gt; Haniwa SP1W33 horn speakers ($60,000/pair) use Electrovoice drivers loaded with midrange and low-frequency horns that continue the Tractrix flare around to the rear of the horn to minimize edge reflections. A separate DSP processor, the FPIC-100 Sound Signal Controller is used to correct the horns' phase characteristics independent of the amplitude response.

Having waxed ecstatic over the big M&#228;rten full-range loudspeaker on display at last October's Rocky Mountain Audio Fest, I was delighted to discover the somewhat smaller $30,000/pair The Bird on display in two virtually square, air-walled conference rooms at the Sands/Venetian Convention Center. The three-way speaker, with a 6 ohm impedance, boasts a frequency range of 28Hz&ndash;45kHz, and is 89dB sensitive at 2.83V.
