Lars Goller proudly rests on the GamuT Phi7 (price tbd), which couples five-midrange woofers in what he calls "perfect unison," thanks to GamuT's proprietary DC Coupled Midrange technology and Acoustic Coupled Driver technology. He says the tall, thin baffle, which arrays the woofers along almost its entire height, delivers excellent acoustic coupling to the listening room.

Omaha was showing this nifty little 10Wpc No.OD-300B integrated amplifier ($1400), which was driving Omaha's Omaha Speaker (price tbd). Do I need to say that the No.OD300B uses a pair of 300B tubes? The system sounded warm and spacious. 10Wpc may not sound like much, but the Omaha speaker seemed comfortably driven. Fit'n'finish were impressive.

Logitech, which has acquired <A HREF="http://www.stereophile.com/news/102306logitech/">Slim Devices</A>, was showing its $499 Harmony 1000 remote. The H 1000 has a 3.5" touch screen that allows you to configure a control pad that features only those functions you need regularly. That means that Squeezebox and Transporter owners like me can say goodbye to scrolling into menus three or four command lines deep. That means heavy users like me might actually find a remote worth $499.

Class D HF Component

Forums

I am curious about the high frequency (ultrasonic) output from class D amplifiers. I have seen this output in tests in Stereophile. My concern is that we have always been told that most speaker damage is caused by amplifier clipping and the resulting high frequency energy created by clipping.
Is this ultrasonic energy insignificant compared to the energy created by clipping?
