Carrying the signal...
Caring for the music.
The development of the SR4 and
SR8 speaker cables started soon after the launch of the new JMF Audio's product
line. Between the HQS power amplifiers and the HPM loudspeakers, there
had to be a link of the highest quality. Considering
that significant signal power is drawn, JMF Audio's pragmatic approach
prevailed in this domain too: pursuing the lossless, with musicality. A challenge...
JMF Audio already proposed the
CM4 modulation cable, so the owners of the brand's elements expected an extraordinary speaker cable. As explained
in the History of the brand, 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 back in the 80's. 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 SR4 speaker cable was the first model of this
new generation, then the SR8 became the reference, featuring twice as many conductors and an extremely low
impedance (confirmed with JMF Audio developed measurement tools), guaranteeing an absolute lossless
original SR4 was instantly acclaimed among JMF Audio equipment owners for
the astounding openness and light on the musical rendering. The following
SR4 and SR8 models have elevated the pleasure of listening in numerous
The SR4 and SR8 are
in-house by JMF Audio. The conductors are made
of highly pure long crystals. Starting from SR4-C and SR8 models, the construction
has been totally symmetrical as valued in JMF Audio's designs. The whole cable assembly requires very
precise conductors and shield placement for optimal sound result. The
manufacturing is a long process. The latest SR4-C
and SR8-C models feature the EHF super shield with an additional link to
chassis ground, which further improves immunity
interferences and electrostatic charges that are responsible for sound blurring.
The SR4-C and SR8-C
are distinguished by a soft natural, faithful and homogeneous sound, the rightness
of timbres and an
exceptional coherent deep and wide three dimensional soundstage. Instruments of an
orchestra appear at the real place, letting the listener feel the space
surrounding the musicians.
The SR4 and SR8 cables have
been the link of choice between different configurations of power amplifiers
and speakers for numerous music lovers, passionate or professionals. The SR4 and SR8 cables
also provide a matched link between JMF Audio HQS power amplifiers
and JMF Audio HPM speakers, especially when fitted with JMF Audio's specific LSS terminals
(loss less dia. 6mm PGP gold terminals - 120A current rated).
Since 2016, version C of SR4
and SR8, each individual cable has been 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
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.
