Premiere Design

The history of recorded music is a long and storied one that is worth preserving for future generations. Unfortunately, the earliest examples of the recording arts are difficult if not impossible to hear anymore. Many wax cylinders and shellac discs are crumbling in archives, unable to be played because any physical contact with a stylus would cause irreparable damage. Even those that can be played often suffer from lots of surface noise and scratches that cause clicks and pops. And many are broken, making even the most careful stylus-based playback impossible.

When you think about the components of any audio system, things like speakers, power amps, and source devices undoubtedly come to mind. You might even consider the room as a component. But what about the seat in which you sit to enjoy the music? Most chairs are not designed specifically for that particular endeavor, leaving you with a pain in the neck and/or back after extended periods, and some actually interfere with perceiving the best possible sound. To overcome the limitations of this "forgotten component," a Swedish company called <A href="http://www.klutzdesign.com">Klutz Design</A> has developed the Ballerina Sweetspot, a prototype chair that is optimized for just one thing&#151;listening.

To celebrate its 30th anniversary, Danish speaker maker <A href="http://www.dynaudio.com">Dynaudio</A> released a special-edition model called the Sapphire in 2007. Limited to 1000 pairs worldwide, the final 30 will be wrapped in an exclusive gloss-blue piano-lacquer finish.

Recently, I posted an <A href="http://blog.ultimateavmag.com/ultimate-tech/let_there_be_let/">entry in the Ultimate Tech blog</A> about a new type of tweeter called the Leading Edge Transducer (LET). In that article, I made some statements to which reader Noah Katz, a structural engineer and, presumably, an audiophile, took exception. At first, I was going to ignore him because he refused to engage in a dialog about it. But, being me, I couldn't resist digging deeper to uncover the truth. After all, one of my guiding principles as a technical journalist is to get the facts straight, and if I don't&#151;which, as a human, is inevitable once in a while&#151;I feel compelled to correct my mistakes.

Audiophiles know the name Mark Levinson well. After his eponymous first enterprise was purchased by Harman International&#151;which means he can no longer use his own name on audio products&#151;Levinson went on to found several other highly regarded audio companies, including Cello and Red Rose Music. Now, in a story exclusive to <I>UAV</I>, the audio designer, recording engineer, and professional musician is launching his latest venture from his adopted home country of Switzerland, calling it <A href="http://www.danielhertz.com">Daniel Hertz, S.A.</A>&#151;"Daniel" after his father and "Hertz" after his mother's great-uncle Heinrich Hertz, whose name is now used as the universal unit of measurement of frequency.

Transducers&#151;devices that convert one form of energy into another&#151;are among the most mature technologies in the audio world. The most common musical transducers are microphones, which convert the mechanical energy of acoustic sound waves into electrical signals, and speakers, which do exactly the opposite. Both have been around for a century or so, and despite a few innovations and variations, they haven't changed much in all that time.
