SR8 (SR4) speaker cables line







SR4B (top) / SR8 (bottom) 

The development of the SR4 and SR8 speaker cables started soon after the launch of the new JMF Audio's product line. Indeed between our HQS power amplifiers and our HPM speakers, there had to be an ultra qualitative link. JMF Audio already proposed the extraordinary CM4 modulation cable, so clients expected an extraordinary speaker cable from JMF Audio. As explained in the presentation section of this web site, 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. We started with the SR4 speaker cable and ended up with the extraordinary SR8 reference, featuring twice as much conductors section and an extremely low impedance, which is required for a loss-less link. 


The SR4 and SR8 are built in-house by JMF Audio. The conductors are made of highly 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.


Compared to other hi-end or professional cables, the SR8 provides a sweet natural and homogeneous sound, which means a great accuracy of timbres and an exceptional coherent deep and wide 3D soundstage. Instruments of an orchestra appear at the right place and sound natural. The SR8 cable is immune to the microphonic effects (vibrations) and electromagnetic interferences that are both responsible for sound blurring (i.e. dynamics compression, harshness, soundstage reduction, resonances). 

It has to be noted that some cables manufacturers have made their reputation on providing magic-box featured cables; most of them showing variable impedance and corrupting signal phase. Some say it is necessary in order to to cope with common systems problems. We believe these are wrong solutions. Precision as seen by JMF Audio has proven superiority to any tweakings when it comes to true musicality.  


The SR8 cables provide a matched link between JMF Audio HQS power amplifiers and HPM speakers. Moreover the JMF Audio's specific LSS terminals are used at both ends (LSS loss less dia. 6mm PGP gold terminals - 120A current rated). However the concept is not exclusive ; the SR4 and SR8 cables have linked JMF Audio HQS power amplifiers to a good number of other speakers at client's places with great results.

Although the SR8 has become the JMF Audio reference, we decided to upgrade the SR4 speaker cable to make it a light variant of the SR8. It is referenced as SR4B. As opposed to the SR8 that features JMF Audio LSS specific terminals, the SR4B features standard fork terminals.

Clients' comments:

Mr. J-P. (HPM500, HQS9001, PRS1.5, DXC6.10, SR8, CM4B)

"I am coming with my Transparent cables to compare to the SR8, if you agree [...] Well, ok, understood..." (2008)


Mr. O. G. (HQS7001, DXC2.2MKII) formerly Jena Labs cables

"The more JMF Audio elements I add (CM4B, SR8), the closer I get to the natural sound I have always looked for" (2012)


Mr. A. M. (HQS9001, PRS1.5, SR8, CM4) large Avalon speakers

"I purchased my previous expensive cables because my speakers were said to have been designed using them. In the end the SR8 provides a much better control, definition, soundstage and overall musicality" 


Mr. W. (HQS3200) TAD drivers studio monitors, Asia 

"My friend thought his speakers may be getting old. We tried my SR8 cables on them and they felt young again! [...]. He'll surely order a set soon" from friend M.I. (HQS7001, PRS1.5, CM4B, SR8)


Mr. D.H., (HPM500, HQS9001, PRS1.5, CM4B, SR8) 

"I replaced all my highly regarded speaker cables with JMF Audio SR8. There was no point in keeping them."


Mr. L.R. (SR8, PC3) formerly Stealth cables

"I received the cables last Friday, which allowed me to listen longly over the week end. Needless to tell you what the SR8 bring me since you know them better than anybody, I am just totally satisfied."


Mr. S. D. (HQS6002, DXC2.2, CM4, SR4) JBL speakers

"Now that I use the SR4 cable, I can turn up my monitors tweeter gain to 0dB, which was unbearable before" 




Initial release, unique pure long crystal conductors, successor of SR4A.

SR8 is the JMF Audio reference speaker cable (UHP ultra high precision)

SR4B: Release of B version, as a smaller and more affordable version of SR8 and featuring traditional fork terminals

Previous models:

SR4(A) Conductors splitter made of walnut with laser engraved signs and logo. This cable does not feature the unique PLC pure long crystal conductors.


Initial release, different metals for conductors, possibility to screw forks, banana or JMF Audio dia. 6mm terminals. This cable does not feature the unique PLC pure long crystal conductors.
