John Tchilinguirian: Energetic Speakers

Canadian speakers from such companies as Mirage, PSB, and Paradigm have acquired international reputations for offering good sound at more-than-competitive prices. The latest Canadian speaker manufacturer to hit the big time might well be Energy, which has actually been around for about 15 years, but has only recently introduced a flagship speaker. Energy's $6000/pair Veritas v2.8 earned Tom Norton's commendation for having produced one of the best sounds at the 1993 Las Vegas WCES. [TJN's">http://www.stereophile.com//loudspeakerreviews/551/">TJN's review appears in this issue.—Ed.]


Ed Meitner: Audio Maverick

Ed Meitner is one of those rare individuals who charts his own course in audio product design. From his platterless turntable of the mid-1980s to his new Intelligent Digital Audio Translator (IDAT, reviewed elsewhere in this issue), Ed Meitner's products have been distinguished by original thinking and innovative engineering. Although not all his designs have been commercially successful, in each he has attempted to advance the state of the art by rethinking fundamental principles.


Ed is also pursuing an ambitious project that would radically change the way recordings are made. It began when he recorded an electric guitar through a 10" guitar-amp loudspeaker and was dismayed that it was impossible to even come close to capturing and realistically reproducing this apparently simple sound through another 10" speaker. This experience launched his investigation into why reproduced sound is never mistaken for live music, a quest that may result in a radically new recording technique.

Mike Moffat: Re-Creating the Musical Event


His background may have been in tubed audio product design, but Theta Digital's Mike Moffat is now at the forefront of computer-based digital processor development. His Theta D/A processors are among a handful of products that use Digital Signal Processing (DSP) chips and custom filtering software instead of off-the-shelf filter chips (footnote 1). I recently visited Mike at the Theta factory to get his current ideas on digital audio reproduction and what goes into designing a good-sounding processor. I began by asking Mike if he had always been an audiophile.

Steve McCormack: It's All In The Details

Steve McCormack has carved out an unusual niche for himself in high-end audio. While working as a hi-fi salesman, Steve successfully modified an amplifier for a customer and promptly decided that there was a market for improving the sonic performance of other companies' products. Thus The Mod Squad was born, a company Steve and long-time partner Joyce Dudney Fleming established to offer high-end modification services.


As Reviewers See It

Every summer, I invite a representative sample of Stereophile's equipment reviewers to the magazine's Santa Fe HQ. For the third successive year, I decided to tape some of the free-for-all discussion that takes place and offer readers the opportunity of peeking over the participants' shoulders by publishing a tidied-up version of the transcript.

Nelson Pass: Simple Sounds Better

As one of the founders of Threshold Corporation, its present chairman, and its longtime technical head, Nelson Pass has had a hand in the design and implementation of the products to come out of that company since its inception. His SA-1http://www.stereophile.com/solidpoweramps/16threshold">SA-1; power amplifier and FET">http://www.stereophile.com/solidpreamps/987fet10">FET 10 preamplifier have been long-term favorites of Stereophile founder J. Gordon Holt and I reviewed the Threshold">http://www.stereophile.com/solidpoweramps/1290thresh">Threshold SA-12/e power amplifier a year ago (Vol.13 No.12). I cornered him on a visit to Santa Fe...


David Manley: Tubes, Logic, & Audiophile Sound

As founder of California-based Vacuum Tube Logic of America, David Manley is at the forefront of the current renaissance in vacuum-tube audio equipment. In addition to manufacturing some highly regarded audiophile components, VTL has introduced a line of tubed professional equipment that is finding its way into recording studios. David has a lifetime of experience in tube electronics, recording studio design, disc cutting, music recording, and most recently, analog/digital and digital/analog converter design.

Stereophile's Writers on an Audio Quest

One Saturday afternoon in August 1990, a number of Stereophile's writers—John Atkinson, Arnis Balgalvis, Robert Deutsch, Larry Greenhill, Robert Harley, J. Gordon Holt, Richard Lehnert, Guy Lemcoe, Lewis Lipnick, Peter Mitchell, Tom Norton, Dick Olsher, Don Scott, and Bill Sommerwerck—gathered together in the magazine's Santa Fe, NM listening room to discuss the "Recommended Components" listing that was due to appear in the October 1990 issue. To add a little Tabasco to the proceedings, JA had invited AudioQuest's main man Bill Low (above) to give a short talk on whatever subject was uppermost in his mind that weekend, to be followed by an open discussion.

Audio, Precision, & Measurement: Richard Cabot

Dr. Richard Cabot is one of today's foremost authorities on audio measurement and testing. Formerly an instrumentation designer at Tektronix, Dr. Cabot is now Vice President and Principle Engineer at Audio">http://audioprecision.com/">Audio Precision. The company's System One, a computerized audio test set (used by Stereophile), has revolutionized the way the world measures audio equipment.
