in electronics, Jean-Marie Fusilier founded his company in 1974. It specialized in high frequency and infra red
remote control systems for critical industrial and defense applications. The audio department was created in 1985, as
a side project named JDF Audio driven by the passion for higher fidelity music
playback. At that time Jean-Marie Fusilier who had significant experience
in tube amplifiers design, developed ultra linear audio solid state power amplifiers
with an unprecedented approach : high voltage rails for improved
resolution, high current enabled outputs for the best control of the
speakers, selected and matched transistors for linearity, selection of
high purity materials to carry the signal, ultra short path circuit
design, direct coupling, enormous internal energy reserve for best
transient response, made to measure passive components by specialists in
aerospace and defense, use of techniques and
components normally intended for telecom and radar systems... to serve the
a presentation in Germany in 1988, these innovative power amplifiers
caught the attention of René Zingg, the passionate sound engineer and
owner of the newly built Soundville studios in Luzern, the first
world-class recording studio in Switzerland.
Zingg asked for the evaluation of the JMF Audio power amplifiers
technology for the control room (the isolated room in which the sound
engineer and the producer evaluate the technical choices and monitor the
overall sound result). A stereo amplifier was compared to the already
installed famed Swiss mono blocks. René Zingg was so amazed by the
natural sound that Tom Hidley, the American designer of the studio, was
advised to come and listen. Tom Hidley approved but challenged
Jean-Marie Fusilier to build a power amplifier with 3dB more level. This
meant twice the output power! The technology did not allow it a such, but
of course the challenge was taken up.
Nashville, USA, the music
city, 1989. The greatest studio complex of Nashville
(recording/mixing/mastering operating 24h a day), designed by Tom Hidley
and standing as his reference, was the place where critical measurements
and sound evaluations of the new JMF Audio purpose made HQS3200 mono
amplifiers had to take place. Comparisons with the installed trusted Swiss
made mono blocks were carried on by the highly focused engineers.
Measurements first: No phase shift... The engineers were used to measuring
a significant delay between the input and the output in high frequency,
even on reference power amplifiers. They checked the measurement
instruments again, but Jean-Marie Fusilier informed them this was
normal... The noise floor was the lowest... normal again. Then other
engineers evaluated the sound. They spent all
night placing tapes on the reel-to-reel desk, replaying and listening to
their previous productions... On the next morning the faces were marked by
hours of questioning. The JMF Audio power amplifiers sounded more
transparent, more natural, more accurate with undistorted bass.
Marie Fusilier's creation was simply faithful. An
engineer said: "if we had used these power amplifiers, we wouldn't
have mixed the way we did...". This
conclusion resonated in the studios world where engineers put
great confidence in the monitoring system...

the studio had to be preserved.
