In late March, the trade organization launched a new salvo of lawsuits against 532 individuals and 21 university computer networks across the country—89 of the accused violators used school networks for downloading or sharing large numbers of copyrighted recordings.

From the March 2004 issue, Kalman Rubinson files his report on the <A HREF="http://www.stereophile.com/amplificationreviews/304adcom">Adcom GFA-7805 five-channel power amplifier</A>. KR notes, "It was easy for me to decide on their top-of-the-line five-channel powerhouse, the GFA-7805, because it embodies the same spirit that the GFA-555 did in its time: lots of power, no frills, good value."
