As to the manufacture of the cables:

Raw materials: For the cable itself, it starts with the copper used in the cable. While Oxygen Free Copper (OFC) sees copper alloys that are electrolyticaly  refined to become 99.9% pure, contrary to salesman’s hype, this OFC does not promote any better performance than when using standard copper and where we value it more for its chemical purity setting a manufacturing standard over any electrical conductivity. While Oxygen Free Electronic (OFE or called OCC) wire is available and in which is in fact 101% more efficient than OFC and regular copper wire, for audio applications there is no “audible’ or “electrical” benefit.







This copper is then drawn through a die, creating a strand of wire that is very thin. This strand of copper wire is then annealed, (heated),  so that it becomes flexible.

These fine single strands of solid copper are then spooled awaiting the weaving process where these single strands are then combines and then woven with a very tight and controlled pitch creating a copper wire awaiting the next step, adding an insulating cover, thus creating an insulated  “core” of stranded wire.


In the KirmussAudio top of the line  “Adrenaline” audiophile high resolution cable, 72 strands make one conductor: then 24 such insulated cores are used, 12 for the plus terminal identified by its clear Polyolefins insulation showing the copper weave, and 12 for the negative pole with white insulation.


Cables are terminated with Rhodium Plated Banana tensile cinch banana jack connectors, and then are sweep tested before packaging and shipment.

End result: The 24 core design results in a neutral 2 x 7 Gauge stranded OFC conductor using the Litz wire braid concept providing a uniquely qualified very affordable loudspeaker cable with excellent voltage response, imaging, soundstage, and timber highlighting your source!

An Introduction to KirmussAudio Hi-Resolution Loudspeaker Accessory Cables

There has been much debate among audiophiles as well as engineers as to the truth that cables make loudspeakers sound better or worse. One would say and many manufacturers would  advertise where the best replication of the source material is to have a “direct connection” between the amplifier output with the speaker itself, therefore forcing their point of view where a $23,000 cable would outperform a $300 cable set. ..but alas, drivers, mid range and tweeters that make up a loudspeaker sees an amplified audio source pass through a complex set of components and coils in a crossover within the speaker enclosure thus already affecting what would be termed a direct one to one connection.  While many manufacturers also test their designs trying to match a reference, one needs to understand  the fact where the ultimate loading also varies between speaker manufacturer with the same amplifier. That is why there is much discussion about cables, sound and auditor’s perceptions.  Hearing is believing and in any purchase, the entire system either works or does not not work for an audiophile.

Just as there is no such thing as a perfect amplifier, there is also no such thing as a perfect load. Speakers are especially horrendous in this respect having significant reactance, which varies with frequency. There is no such thing as an amplifier with zero output impedance and as a result all amplifiers  are therefore influenced to some degree by the load. The load being also modified by the audio signal carried by the loudspeaker cable.

An ideal load is perfectly resistive which has no reactive elements  such as inductance or capacitance are present. Hence the reference to a “direct connection”.  Just as there is no such thing as a perfect amplifier, there is also no such thing as a perfect load. Speakers are especially gruesome in this respect, having significant reactance, which varies with frequency. They of course are connected by the speaker cable to the amplifier. Get the drift?

Then how then do cables affect soundstage and the like?  Many a time, this is all one’s personal perspective. As a manufacturer of cables, there are though, technical resources to review and appreciate.

One aspect is where the LR Series Circuit and LC Resonant circuit of the cable introduced between the speaker and how the amplifier itself reacts to the various crossovers within the loudspeaker and how they play into the loading of the amplifier’s output as well as reverse reflections to the amplifiers output are in fact of consequence.

While amplifiers have 4 and 8 ohm outputs, twin (zip wire) cables all have significant inductance which increases proportionally in length. With an amplifier rated at 20 Watts and with an 18 gauge rated zip cord of 12 feet saw the response change 2.9 dB, quite significant, when now increasing length  to a length of 18 feet. This change was audible and unacceptable. All amplifiers are affected by the load, and therefore all amplifiers must show some degree of sensitivity to the speaker lead and speaker.  How it affects one’s perception of  soundstage and imaging is up to the audiophile. In fact, keeping the same speaker and cable and changing amplifiers also changes the perceived soundstage and imaging, as amplifier final circuits are all different and react differently to cables.

As a result, all KirmussAudio cables strive for a balance and for a near neutral affectation as part of the tank circuit the loudspeaker cable creates as the intermediary carrier between the amplifier and loudspeaker.

The Kirmuss Audio’s “Adrenaline” model cable features this approach. Added, terminations are made using Rhodium plated copper.  Rhodium is considered best in class of all the platinum metals family for resistance to corrosion and tarnish. As it is extremely hard, it is better than gold plating. In speaker applications we see many audiophiles move cables around, Rhodium is a better choice for this making this contact on both amplifier and speaker ends. As this happens frequently, our banana jacks feature a tensile “cinch”, holding the able in place.
