So where did we leave off? I think you were wandering around the listening room clapping your hands. You were, I hope, listening to the slap echo and noting how it changed as you meandered about. That's probably just when someone near and dear bumped suddenly into the room and gave you that peculiar look we audiophiles know so well. Try to explain what you're doing.

For years, credit cards have allowed people to earn points toward air travel and automobiles, so earning credits for audio and video gear seems a no-brainer. Last week, Sony Electronics and Citibank launched the <A HREF="http://www.sony.com/sonycard">Sony Citibank Card</A>, a co-branded credit card that allows consumers to earn points toward the purchase of a variety of Sony entertainment and merchandise.

HDCD and <A HREF="http://www.hdcd.com">Pacific Microsonics</A> appear to be on a roll these days. The HDCD process, developed to coerce 20-bit performance out of the 16-bit CD format, is gaining several new licensees and is also appearing in more devices, as evidenced by several recent announcements. The company is also looking ahead to future DVD formats with an agreement intended to couple HDCD benefits with higher sampling rates.

Saturday, September 26, thousands of enthusiastic audio-savvy attendees began swarming through the massive cavern of the Moscone Center's North Hall in San Francisco. They will continue to swarm until late Tuesday, September 29, the last day of the 105th <A HREF="http://www.aes.org/">Audio Engineering Society</A> Convention. The convention has attracted hundreds of companies whose products are extravagantly displayed in the huge space beneath the Yerba Buena Gardens. Demonstrations of new products and technologies also take place in smaller rooms off the main floor. Research papers are being presented in meetings throughout the four-day event.

James Bongiorno needs your help. The legendary electronics designer, whose pioneering work with fully complementary solid-state amplifiers has become part of engineering's standard lexicon, is battling liver cancer.

It's cheating to say that the best sound I've heard at the English Show was at Martin Colloms' house on Saturday night---cheating the same way it is when someone asks that question and I (or some other reviewer) piously responds that some live music event ranks above any exhibitor. Martin, of course, has an advantage over anyone at the Show. He set up his own listening room and had all the time he needed to boot. Even so, his system, consisting of a Krell KRS-25 and FPB 650Ms and Wilson Audio WITT IIs, was astoundingly fast, rhythmic, and dynamic.
