About the Designer of your HCA-1200II

We created your Parasound HCA-1200II to be among the finest amplifiers ever made for the reproduction of
music. To build a world class amplifier, we turned to world class designer, John Curl. John is considered one
of the most respected designers of our time. His advances in the art of audio have been renowned for over 20
years. And now his legendary quality has been brought to home audio and home cinema reproduction.

John was the designer of the Mark Levinson JC-2 preamplifier in 1974. A landmark product whose perfor-
mance justified its stunningly high price, it inspired the emergence of the high end audio industry. He de-
signed the mastering recorders used by Wilson Audio and Mobile Fidelity, the mixing consoles used by the
Grateful Dead for concerts and recordings, and electronics at the site of the famed annual Montreux Jazz
Festival in Switzerland. Most recently he has redesigned the recording electronics for Stereophile Maga-
zine.

John has published definitive articles on advanced circuit design and the influence of different capacitor
types on the reproduction of music.  He designed the Denneson JC-80 preamplifier, Symmetry electronic
crossover, SOTA head amplifier and collaborated with noted Finnish designer Matti Otala in explorations of
the phenomenon of Transient lntermodulation Distortion.

John also builds the wonderfully musical, quiet (and very expensive) Vendetta Research phono preamplifi-
ers which have earned rave reviews in AudioThe Absolute Sound and repeated Class A distinction in
Stereophile. He designs and builds the products the top reviewers purchase for their own listening pleasure.
Those who can afford his designs have been a privileged few. Take another look at some of the special
features in your Parasound HCA- 1200II - these are the hallmark of the finest,  most musical high-end audio
models which have earned critical acclaim.
And now they're yours.
