With their simple circuits and low, even zero, levels of loop negative feedback, the sound quality of single-ended triode amplifiers is very dependent on the specific output tubes used. In "<A HREF="http://www.stereophile.com//features/229/">In Search of the Perfect 300B Tube</A>," Peter van Willenswaard finds that not all tubes are created equal. Measured and auditioned in his survey of 300B power tubes are samples from Golden Dragon, JJ Electronics, KR Enterprise, Sovtek, Svetlana, Valve Art, and Western Electric. "If you want the best," sums up Mr. W, "there's only the . . . "&mdash;well, you'll have to read the article to find out!

Music file&ndash;sharing service <A HREF="http://www.napster.com/">Napster Inc.</A> appears to be losing its fight against the <A HREF="http://www.riaa.com/">Record Industry Association of America</A>. On May 8, judge Marilyn Hall Patel of the US District Court in Northern California rejected two of Napster's key defenses: that it is a "mere conduit" of information, like a telephone network; and that it had made serious efforts to prevent "repeat offenders" from using the site. Telephone companies, Internet service providers, and other types of information services are exempt by law from being responsible for the information transmitted over their systems, provided they make reasonable attempts to control abuses. Napster doesn't qualify on either count, Judge Patel found.

Digital downloading is all the rage with the major record labels. <A HREF="http://www.emimusic.ca/">EMI Recorded Music</A>, a unit of <A HREF="http://www.emigroup.com/">EMI Group PLC</A>, announced May 10 that it will make some of its massive catalog available as digital downloads beginning this summer. More than 100 albums and 40 singles will be offered on a trial basis, according to a company press release dated May 10. EMI's musical spectrum covers every genre, including pop, rock, jazz, classical, Latin, Christian, country, rap/urban, and dance&mdash;a roster of approximately 1500 artists. Labels under the EMI umbrella include Capitol, Angel, Blue Note, EMI, Priority, and Virgin.

I can't resist reading about a company's flagship loudspeaker&mdash;the price-no-object product that embodies the most advanced ideas from a company's research and design department. Flagship loudspeakers tend to be large, heavy, and complex, and are designed to perform best in large rooms; often, each part of each driver is hand-built to the highest level of quality, with precisely tight tolerances. The cost? Don't ask. Some two-channel, audio-only flagships cost more than a BMW M5 sports sedan or a Porsche 911.

In this issue's "Letters" column, you will find comments from readers who are bothered by what they perceive to be this magazine's emphasis on reviewing very expensive technology. Yes, we do cover a lot of cutting-edge technology, and it is, of necessity, expensive. But our experience has been that that technology invariably trickles down to products that real people can actually afford.

Each year we do a survey to see which dealers deserve special mention. Who has impressed you the most in the last 12 months?

The continuing legal attacks on <A HREF="http://www.napster.com/">Napster</A&gt;, the free file-sharing software, and on <A HREF="http://www.mp3.com/">MP3.com</A&gt;, the downloadable music site, have spooked investors, according to the financial press. MP3.com's stock got hammered hard, dropping by about 40% almost immediately in the wake of a <A HREF="http://www.stereophile.com/news/10737/">recent decision</A> by US District Court judge Jed S. Rakoff in favor of the <A HREF="http://www.riaa.com/">Recording Industry Association of America</A>'s copyright-violation complaint against the Internet startup.
