Carrying the signal...
Caring for the music.
As it has
been explained in the pages related to the history of the make, the type and the purity of
the materials and their associations for sound neutrality has been the
second point of research of Jean-Marie Fusilier. Indeed his main activities
were in high frequency electronics, in which field engineers pay great
attention to materials and shields for proper signal propagation and
signal integrity. The CM4 is the result of years of development,
formerly in cooperation with specialists in vinyl playback in Europe. The CM4 cable was then
presented along with the HQS power amplifiers and was systematically chosen by
the descerning studio
professionals and music lovers in the USA, Europe and Asia. Excellent
products stand the test of time.
manufacturing of the CM4 cable draws upon exceptional tooling and
materials. The conductors are made
of extremely pure long crystals. The construction is totally symmetrical as
always with JMF Audio's designs. The whole cable assembly requires very
precise conductors and shield placement for optimal sound result. By design, the CM4 cable
preserves signal integrity, is virtually immune to microphonic effect (vibrations) and electromagnetic
interferences that are both responsible for sound blurring.
The CM4 cable is distinguished by a
soft natural, faithful and homogeneous sound, timbres rightness and an
exceptional coherent deep and wide three dimentional soundstage. Instruments of an
orchestra are at the right place and sound natural.
CM4 cable has linked audio devices in different setups with excellent
results. It also
creates a matched link between JMF Audio elements (DXC2.2 converters, PRS1.5 preamplifier, HQS power amplifiers). The philosophy is
preserved, especially with the latest cable version.
can manufacture single ended (RCA connectors) versions on demand, which
starting from revision E, take full advantage of the symmetrical design of
CM8 is based on the CM4 and features advanced mechanical damping and shieldings for superior immunity to noise, electromagnetic
interferences and vibrations. As a result the CM8 has a greater diameter
and a different finish. The manufacturing of the CM8 is a longer

identified with a serial number with the corresponding manufacturing and
measurement notes stored in JMF Audio's files. Before delivery every cable
has passed through a break-in period and listening tests in our studios for
verification compared to our references. We are proud to deliver our
latest models to you in the deluxe boxes they deserve.
