When I attended the Audio Engineering Society convention in October 1987 (my first time in over eight years; full report in this issue), I was impressed by the incredible technology now available to composers of music. I was also dismayed, however, by the extent to which so-called purist audio, as well as "acoustical" music, have been consigned to oblivion by the pro audio community. It was clear, both from the exhibits and the many conversations on which I eavesdropped, that audio professionals are no longer concerned about fidelity, in the sense of trying to reproduce sounds accurately. A "real" sound has become to them merely raw material of no value except as something to be processed, manipulated, folded, bent, and spindled to produce any sonic effect except the original one. About a third of the products displayed at the 83rd AES convention were tools for doing that.

During the past 10 years, perfectionist audio has garnered for itself an impressive accretion of lore, much of which has never been accepted by the so-called scientific community.

Many audiophiles who have only recently subscribed to Stereophile will be surprised to find that those clunky, heat-producing, short-lived tubes that reigned up through the mid-'60s are still Executive Monarchs in the mid-'80s. Why, for Heaven's sake? Because, despite everything, people like them.

A reader who asked to remain anonymous wrote to tell us the results of some tests he saw conducted on one of our top-rated loudspeaker systems. Frequency-response checks showed that the system had virtually no deep bass, a midbass peak, a midrange slump, and a high-end rise. Further checks had shown gross distortion at input levels of over about 6W, and a definitely limited (although adequate for Row-M listening) maximum output-level capability. Said reader then went on to ask how we could possibly consider such a speaker to be one of the best available.

Before launching into Stereophile's first-ever report on a Mark Levinson product, an important point needs to be clarified. Although Mark Levinson products were originally made by Mark Levinson, they are no longer. Au contraire, Mark Levinson products are now being made by Madrigal, Ltd., which bought Mark Levinson Audio Systems' assets and trademark two years ago. Mark Levinson's products, as distinguished from Mark Levinson products, are now being manufactured by a company called Cello. But the subject of this report, the Mark Levinson ML-7A preamplifier, is a product of Madrigal, Ltd., not of Cello. Now that I've made that all perfectly clear, we may proceed.

Is it possible to make a $700 "mainstream-audio" power amplifier sound exactly like a high-priced perfectionist amplifier? Bob Carver, of Carver Corporation, seemed to think he could, so we challenged him to prove it.

In my rather jaded report">http://www.stereophile.com/asweseeit/the_1986_winter_ces/">report from the 1986 Winter CES (Vol.9 No.2), I remarked that there was nothing really new in the field of high-end audio. Well, I was wrong. I overlooked the Acoustic Sciences Corporation Tube Traps, a patented new acoustic device designed by Arthur Noxon (president of ASC). The Traps represent the first practical and effective solution to a perennial audiophile problem: standing waves in the listening room.
