LATEST ADDITIONS

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.

Needing a shot of the real thing after a particularly disappointing dem from another manufacturer, I headed down the hall to hear Aurum Acoustics' total package. ($48,000 gets you the Integris CDP CD player, Integris Active 300B amplifier and speakers, Integris two-shelf Isolation Rack in matching veneers, 2m power cable, Aluminum Base kit, and Loudspeaker Grille Kit. As I said, the whole package.

Mark Levinson showed a design study for its Reference No.53 monoblock amplifier in its Hilton suite, which will replace the previous flagship, the No.33. Although details are not finalized, Levinson's Walter Schofield suggested that each monoblock chassis will be rated in the neighborhood of 500W into 8 ohms, and will be priced at approximately $20,000.

The McIntosh MC 275 power amplifier has been born yet again. It's the Count Dracula of power amps. It refuses to stay dead. Introduced in 1961, the Mac 275, in its original hardwired edition, was produced until 1970. This was the amp I desired while in college but couldn't afford. I remember the Mac 275 fondly&mdash;rather like girlfriends from my college years.

It's called the "Cocktail Party Effect." You may be immersed in the middle of a crowd of audiophiles all talking at once, but when someone says something that catches your attention, such as your name, you can focus on the sound of that person's voice and exclude the babble. The noise suppression can be 9&ndash;15dB; <I>ie</I>, the sound being concentrated on seems to be three to four times louder than the ambient noise, according to <A HREF="http://en.wikipedia.org/wiki/Cocktail_party_effect">Wikipedia</A&gt;. The exact mechanism of the Cocktail Party Effect is not known, but it is conjectured that it has something to do with the binaural nature of human hearing: the fact that we have two ears allows us to apply spatial discrimination to what would otherwise be a jumble of sound.
