From the April 2004 issue, a must-read for all audiophiles: Keith Howard does the SACD and DVD-Audio math for "<A HREF="http://www.stereophile.com/features/404metrics">New Media Metrics</A>." Using a vast collection of informative graphs, KH explores hi-rez attributes and puzzlers. "In the case of SACD, why provide a potential bandwidth in excess of 1.4MHz, only to fill more than 95% of it with quantization noise?"

<I>Stereophile</I> readers are clearly in <A HREF="http://cgi.stereophile.com/cgi-bin/showvote.cgi?327">favor</A&gt; of our <A HREF="http://www.stereophile.com/digitalsourcereviews/934/">coverage</A&gt; of products like Apple's iPod. But judging by some of the comments we receive, they're split on whether it's been a kick in the pants for music lovers or just added to the downward low-rez spiral of digital audio.

Have you ever been to a rock concert and come away mumbling, "Those engineers must be deaf"? After enduring three hours of an all-out sonic assault, you were probably just a tad cranky, but the facts are that those engineers probably <I>were</I> deaf, or well on their way.

It's safe to say that few audio engineers are more famous than Ray Dolby. On May 1, the founder and chairman of <A HREF="http:// www.dolby.com">Dolby Laboratories</A> was inducted into the National Inventors Hall of Fame in Akron, Ohio, joining such luminaries as Alexander Graham Bell, the inventor of the telephone, and Thomas Edison, inventor of the light bulb and the phonograph.

Last week, Primedia announced the next in a series of editorial upgrades to its Home Technology & Photography specialty group. The group is redesigning its <I>Stereophile Guide to Home Theater</I> magazine to become <I>Stereophile Ultimate AV</I> (new URL: <A HREF="http://www.ultimateavmag.com">www.ultimateavmag.com</A&gt;) starting with the June 2004 issue. Hitting newsstands May 11, the redesigned magazine will feature 16 pages of new and expanded editorial content for high-end audio/video enthusiasts, more advertisers, and an enhanced consumer-friendly design.

Meeting Englishman Tim de Paravicini for the first time, you start to wonder if your mind has slipped a gear, whether premature brain fade has cut in. The conversation seems not only to be racing by unexpectedly quickly, but also subjects you hadn't even realized <I>were</I> subjects are being examined in knowledgeable depth. It was at the end of the 1970s that I bumped into Tim at a trade show in the UK; having wanted to ask his opinion of tube-amp design, knowing that the gangling, wispy-bearded, Nigeria-born, one-time resident of South Africa and Japan, ex-Lux engineer (footnote 1) had cast a magic wand over the Michaelson & Austin product line, I found myself instead being treated to an exposition of color phosphor problems in TV monitors. For Tim is a true polymath, his mind seemingly capable of running at high speed along several sets of tracks simultaneously.

The story of New Acoustic Dimensions, aka NAD, begins in the late 1970s. The company was founded as a dealer distribution collective to design and market reasonably priced serious high-end gear to cost-constrained audiophiles. By eliminating needless features and focusing manufacturing in low-cost production facilities, NAD has successfully delivered audiophile-quality gear for 20 years at prices little more expensive than mass-market department-store schlock.
