Next, we include an interview conducted by Robert Harley with the creator of the CAD-300SEI, The Single-Ended Amplifier: Cary's Dennis Had. Widely credited with the SET revival in the US, Had explains what drives him and his designs.

In his review of the Cary Audio Design CAD-300SEI integrated amplifier, Robert Harley admits up front that he's been "biased against single-ended tube amplifiers because of their quirky measured performances." Can the Cary redeem itself and the SET approach with a single hearing? Harley reports, with a "Follow-Up" from Jonathan Scull.
Madrigal Audio Labs designed the original Mark Levinson No.30 nearly 10 years ago with the idea that, as a Reference Series product, it would never be made obsolete. John Atkinson reviews the No.30's latest upgrade, the Mark Levinson No.30.6 Reference D/A processor, after sending his personal unit from 1992 back to the factory for the required work. What he got back included new D/A converters in the unit's twin towers. Was it worth the effort, and does this processor still define the state of the art? You'll want to read his report to find out.

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 "In Search of the Perfect 300B Tube," 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 . . . "—well, you'll have to read the article to find out!

Federal courts long ago established that music fans have certain "fair use" rights when it comes to making copies of recordings they own. They can transfer recordings from one format to another—such as from LP to cassette tape or from CD to MiniDisc—and they can share those recordings with others, provided that the results are only for private, noncommercial use.
"Fair use" does not include mass replication, however, even if it is for noncommercial purposes. Is Napster, the audio file-sharing Internet service, simply software that lets music fans swap favorites, or is it something more…
Incorporating the company's new "black box" crossover design, the Acarian Alón Li'l Rascal Mk.II loudspeaker captured Robert J. Reina's attention. "I fired up the Li'l Rascals, wondering if I'd catch a glimpse of the dynamic performance I'd heard from the Exotica Grand References at HE2001," explains BJR.
When Art Dudley initially laid eyes on the Reference 3A MM de Capo i loudspeaker, he noted, "At first glance, this speaker looks like a thousand other stand-mounted two-ways on the market." AD then goes on to explain what, other than the odd name, sets it apart.

One of the dirty little secrets of the recording business is that some of its most precious assets are slowly self-destructing. In one example, a popular mastering tape supplied by Ampex to recording studios during the '70s and early '80s has been found to prematurely shed its oxide coating at an alarming rate due to poor quality control of the binding agents that hold the magnetic particles to the Mylar.
Engineers have taken to "baking" these reels of deteriorating tape in a effort to make one or two final transfers before the masters become unusable. But as each day passes, more of the…
UK electronics specialty manufacturer Audiolab has been taken over by leading Grand Prix car-racing company TAG McLaren---or, more precisely, by the TAG McLaren Group. A newly formed company, TAG Electronics Holdings Ltd., will be the parent of both Cambridge Systems Technology Ltd. (which trades as Audiolab) and TAG Electronic Systems Ltd. (which supplies specialist, low-volume electronic engine-management systems to exclusive high-end automobile brands).
TAG McLaren Group's Managing Director, Ron Dennis, shows his mastery of mediaspeak in the following statement: "I am very excited…
"I wouldn't characterize my life as 'a search for bigger and better toys,' but I am intrigued by interesting things—like the Impact Airfoil 5.2 loudspeaker system," says Brian Damkroger as he steels himself for another review. BD goes in search of an answer to the Airfoil dilemma: "big toy, new toy, neat toy, better toy?"
Robert Harley finds himself in a small listening room and assesses the Aerial Acoustics Model 5 loudspeaker to see if it is able to complement his petite environs. Harley notes, "Any manufacturer of large loudspeakers who has set up such a system in a CES hotel room can…
Back in 1996, Martin Colloms reviewed the Krell KAV-300i integrated amplifier, asking, "Is Krell risking its reputation?" He needn't have worried, as the 300i has gone on to become a popular audiophile classic.
Thomas J. Norton looks at an amplifier's output impedance to understand its effect on a system's performance. In Questions of Impedance Interaction, TJN looks at three loudpeakers' interactions with the same amp to illustrate this important phenomena.
At the point of Stereophile's 30th anniversary in 1992, Founder J. Gordon Holt asks Where Did We Go Wrong?. "I've been…
