CES 2007

At CES 2006, Jon Iverson and I were impressed by Studio Electric's $8500 Type One modules, even though the mating $3500 XLR woofer modules weren't operating. This year Studio Electric was showing off a pair of the $15,500/pair Type Two towers, which were pure art deco chromed metal work.

Many of the best-sounding rooms at the show employed Ayre's $16,500/pair 300W MX-R monoblock amplifiers. Yes, they look small enough to be class-D amplifiers, but they're pure analog. How'd they do it? The entire enclosure is the heatsink and Ayre's Charlie Hansen designed a special low-rise transformer, used in pairs, to keep the chassis so compact.

Press conferences can sometimes be tedious affairs, with the presenter going on-and-on about his company's past accomplishments, and how even greater things are coming in the future. But this description did not apply to the press conference for Usher Audio Technology at this year’s CES. This was more like an informal party for friends than the prototypical press conference. People stood around and chatted for a while, and then Atul Kanagat of MusikMatters, Usher’s North American distributor, talked briefly about how Usher’s line of high-value/high-performance loudspeakers is intended to bring more music lovers into the hobby. We then listened to some music through some very-nice-sounding Usher speakers. Pictured are PR consultant Jonathan Scull (whose name should be familiar to Stereophile readers, Usher chief engineer Joe D’Appolito (whose name should be familiar to students of speaker design), Tsai Lien-Shui (President of Usher), and Atul Kanagat.

VTL introduced a new phono preamplifier at CES, the $6500 TP-6.5 Signature Phono Stage, as well as an upgraded MB-450 Signature monoblock amplifier. Using the single-chassis configuration of the TL-6.5 line preamplifier, VTL's phono preamplifier follows its hybrid design approach, using a low-noise J-FET to drive high-current 12AU7 tubes. It features switchable, five-corner, passive RIAA filtering. Gain, cartridge load impedance, phase, muting, rumble filter, and power on/off can be switched by remote.

Behold bills itself as "true digital audio" since it maintains audio as a digital signal up to the amplifier stage. The 600Wpc BPA768 (US price TBD) incorporates 768kHz/24-bit signal processing, a switch-mode power supply, an analog output stage, and an integrated power conditioner.

The 150Wpc Boulder 865 integrated amplifier (approximately $10,000) is only four days old, so we tiptoed into the room in order not to wake it up. Richard Maez (seen here at the back of the photo) was elated that the 865 had actually made it to the show, but he was even happier to run down the details.

When it comes to directivity in loudspeaker frequency response, the trend has been to make them less directional, both vertically and horizontally, so that the speakers would be less sensitive to seating position and allow more then one person to enjoy the same tonal balance. The new Copernicus II ($21,000/pair with powered subwoofers and digital equalization/phase correction) from Alltronics Technical Systems takes the opposite approach, going for maximum directionality/focus. The drivers form a vertical line source with a concave curve, the speakers being "aimed" at a seated listener. Not only that, but there's a motorized control moving the speaker up and down to match the exact height of the listener's ears when seated. These are what I'd call "bachelor’s speakers!" They are certainly not designed for listening by couples, but the upside is the the soundstage can be extremely precise and three-dimensional, and the sound itself was well-balanced and dynamic.
