Description

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 link.

The 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 different setups.

The SR4 and SR8 are hand-built 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 from electromagnetic 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 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.
