Audiophile Inquiries: Unleashing the Potential of High Permeability Braiding in Audio Cables: Elevating Performance to New Heights


Audio cables are the unsung heroes behind high-fidelity sound reproduction. While their significance is widely acknowledged, the fine technical details that shape their performance are often overlooked. Among the key elements that significantly impact audio cable performance are braiding, film shielding, and the innovative application of high permeability braiding. In this article, we will explore the profound effects of high permeability braiding in audio cables and its ability to enhance overall audio performance.

Braiding: Enhancing Durability and Reducing Interference

Braiding involves the interlacing of multiple conductive wires or strands around a central core in a cable. This technique offers a multitude of benefits, including increased durability, improved mechanical strength, and effective reduction of electromagnetic interference (EMI). Different types of braiding, such as loose, tight, or concentric, contribute varying advantages.

One of the primary advantages of braiding is its ability to mitigate external interference. Audio cables are often exposed to EMI generated by nearby electrical equipment or radio waves, leading to unwanted noise and reduced sound quality. Here, braided shielding acts as a protective barrier, creating a Faraday cage that diminishes the impact of EMI on the audio signal.

Enter High Permeability Braiding: Revolutionizing Audio Quality

While traditional braiding techniques are effective in combating EMI, high permeability braiding takes things a step further. By utilizing braiding composed of materials with high magnetic permeability, audio cables can achieve unprecedented performance improvements.

High permeability braiding is capable of significantly reducing the impact of low-frequency electromagnetic interference, specifically in the audio frequency range. This unique property allows for exceptionally clean and accurate audio signal transmission, resulting in enhanced sonic fidelity.

With high permeability braiding, cables can better isolate the audio signal from external magnetic fields, ensuring a pristine audio experience. This technology is particularly advantageous in scenarios where audio equipment and cables routinely encounter magnetic fields, such as in recording studios or broadcasting setups. By limiting the influence of low-frequency magnetic interference, the audio signal remains pure and uncorrupted, allowing for faithful reproduction of the original sound.

Synergy with Film Shielding: A Comprehensive Shielding Solution

While high permeability braiding excels in combating low-frequency magnetic interference, it may not be as effective against other forms of electromagnetic interference. To provide comprehensive protection, audio cables often combine high permeability braiding with film shielding. Film shielding, typically composed of conductive materials like aluminum foil, adds an extra layer of defense against high-frequency interference.

By integrating high permeability braiding with film shielding, audio cables create a robust defense mechanism against a broad range of interferences. Together, these shielding techniques minimize the presence of noise and distortion, resulting in unparalleled sound quality and audio fidelity.


The introduction of high permeability braiding has revolutionized the performance of audio cables, offering an unprecedented level of sound quality and fidelity. By harnessing the benefits of high magnetic permeability materials, audio cables equipped with this innovative technology can effectively mitigate low-frequency magnetic interference, ensuring pristine audio signal transmission. When combined with film shielding to combat high-frequency interference, the result is a comprehensive defense mechanism that guarantees a pure, unadulterated audio experience.

While braiding, film shielding, and high permeability braiding play essential roles in audio cable performance, it’s important to consider other factors as well, such as conductor material quality, gauge, and overall construction. By taking a holistic approach to cable selection, audiophiles can indulge in an audio experience that surpasses expectations. Embracing high permeability braiding opens new horizons for audio enthusiasts, allowing them to enjoy unparalleled sound reproduction that captures every subtle nuance and breathes life into their favorite music.

After thoughts

I know many people will want to know just how big of a change can be expected. The answer is the shielding effectiveness of high permeability over braided film shielded cable material can be as high as 2,000 db all the way down to zero hertz. Which means any noise getting into the system is not getting there through the cable, but the connectors and equipment cases which are not typically magnetically shielded.

One reviewer that reviewed a magnetically shielded cable I designed put it in his second smaller system the first time he tested it. I had informed him they needed another 30 hours to sound as designed. When he finished the review he was working he put the cables on the system. The next morning he called at 6am and told me he had been up all night. He had never heard anything like it before. He talked for hours, at which point my cell phone battery died. I do have one analysis of what technical difference such a design can made to a system, 20 db drop in noise floor was claimed in that paper. I only know of 2 engineers who have designed such cables for the audio business, one being myself. Please note not everyone likes this type of cable, it all depends on what makes your ears and mind happy.

So, is it possible to purchase a product like a simple power cord and improve its performance by adding shielding? Yes! See Furutech video page for more information on shield integration.
