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.

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.

"This won't be a short job," says Arcam's president, John Dawson (footnote 1). He's talking about the challenge of engineering the next generation of Arcam home-theater products to embrace the new high-resolution video formats. It's possibly the biggest technical challenge English company Arcam has faced since, almost exactly 30 years ago, Dawson and his original business partner, Chris Evans, launched their first product&mdash;an unpretentious, 35W hi-fi amplifier called the A&R Cambridge A60.

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.
