There was something odd about the clock on Jim Thiel's office wall. I didn't get it at first, other than noting that instead of the minutes being marked off at 12 five-minute intervals, Jim's clock had 24 markings. That was it: as well as the number "12" in its usual place at the top of the face, there was another "12" at the bottom, where the "6" usually is. The clock that Jim built was typical of everything this laconic loudspeaker engineer is involved in: logical, functional, and different from what anyone else in the same field does. In his cigarette-strained drawl, Jim explained that the short hand of his clock always points toward the sun: directly up at noon, directly down at midnight. That's the way a clock should be, declared Jim, and when you're in his company, it's hard to see how he could be wrong.

In an announcement that could stun the neophyte custom CD compilation business and concurrently impact future prospects for the $12 billion music recording industry, <A HREF="http://www.supersonicboom.com/">superSonic BOOM</A> has signed an exclusive licensing agreement with Ergon Technology for a patented manufacturing process covering customized audio products. Like <A HREF="http://www.openmarket.com">Open Market</A>'s announcement last week that it had received patents from the US government for its e-commerce technology, superSonic's announcement raises more questions than it answers.

March 9, <A HREF="http://www.akm.com">AKM Semiconductor, Inc.</A> introduced the AK5392, a 24-bit stereo analog-to-digital (A/D) converter based on its proprietary dual-bit delta-sigma technology. The AK5392 reportedly achieves a dynamic range of 116dB, said to be a 15dB improvement over other single-chip alternatives.

Remember how your Uncle Charlie used to hole up in the basement with his ham radio rig? He'd spend hours down there, tweaking his equipment and chatting in an arcane jargon with fellow hobbyists around the world.

On March 12, <A HREF="http://ovonic.com.">Energy Conversion Devices, Inc.</A> announced that <A HREF="http://www.sony.com">Sony Corporation</A> has expanded its royalty-bearing license under ECD's proprietary phase-change rewritable optical-memory technology to include advanced technology for use in rewritable CD and DVD optical-memory products. Phase-change technology, invented by ECD, is used in PD and CD-RW rewritable optical-memory discs.

Coming soon on the <A HREF="http://www.madrigal.com">Madrigal Audio Laboratories</A> website is <i>La Folia</i>, a music webzine. Edited by Mike Silverton, <i>La Folia</i> sets out to supplement the audiophile press by directing its emphasis at recordings elsewhere neglected: present-day art music (aka "classical"), free and improvisational jazz, category-defying hybrids, and whatever else strikes their "clutch of sweet-spot stuckees as rare and well done."

High-quality, low-cost loudspeaker systems are not an everyday blessing. The <A HREF="http://www.stereophile.com//loudspeakerreviews/361/">Rogers LS3/5a</A> has survived for more than a decade precisely because so few US manufacturers sought musical accuracy as distinguished from high output and powerful bass. The economics of loudspeaker manufacture also don't lend themselves to economy. The cost of woodwork is driving the price of speakers up almost as fast as the cost of sheet-metal work is escalating the price of electronics.
