The speakers make the difference.
"Do Amplifiers Really Sound Different?" With this article, Peter Moncrief, physicist, audiophile and editor of International Audio Review, entered what he called "the great amplifier debate." Mr. Moncrief's answer was an unqualified 'yes." Ian G. Masters, of Audio Scene Canada magazine, explored the same subject and came to substantially different conclusions. The intensity of the debate suggests that the differences--if any--are small.
No such debate rages with respect to loudspeakers. Critics agree "Speakers do make a difference." And few loudspeakers make as big a sonic difference as ESS loudspeaker systems incorporating the revolutionary Heil air-motion transformer (U.S. Patent no. 3,832,499).
The superiority of a loudspeaker cannot be explained in a few words. But it can be experienced in a few minutes.
Last year, in a demonstration of the superiority of its speakers to untrained listeners, ESS ran direct comparisons between ESS speakers and those of its leading competitors. In 42 out of 43 blind listening tests conducted under the supervision of an independent national testing laboratory, students attending U.C.L.A., the University of Wisconsin and Georgia Tech judged ESS speakers superior to those of JBL, Bose, AR, Pioneer, Advent, Cerwin-Vega and Infinity--sometimes by margins of 3 to 1 over far mere expensive competitive models.
This year, ESS has developed an even more simple test that dramatically proves ESS's superiority in transient response and dynamic linearity". Demonstration clinics will be conducted at participating ESS dealers throughout the country.
Don't miss this exciting demonstration. See your ESS dealer, or write to ESS for more information.
