The Firewire cable employs an entirely new ground breaking structure - DualConduit (TM) - separate cables for the power and signal lines.

Relevation Audio Labs say

"It is widely known that the radiated noise from power cables affects signal cables and damages sound quality when a signal cable and a power cable are installed in parallel or come into contact with each other. However, virtually every Firewire and USB cable available on the market have the signal line and power line in one cable together - we can easily imagine how sound quality is deteriorated by this structure.

Some high-end Firewire and USB cables have independently shielded signal and power lines. However, these two lines are in close proximity in the same cable and are constantly causing noise reflections inside the outer shielding tube which will significantly damage sound quality. The power supply lines in Firewire and USB cables transmit a large amount of 'noise' that is generated by the PC (computer). This 'dirty power' seriously degrades the quality of the signal being transmitted and therefore, audio sound quality is greatly reduced. Although our previous design features discreet shielding for each conductor pole, which is superior to most cables on the market, a feature also included in this latest design, which addresses this issue and is vastly superior to the typical Firewire and USB cable, our DualConduit design offers the ultimate in isolation of the signal lines from the power lines. Our latest-design Firewire and USB cables are equipped with two independent cables consisting of a shielded structure with a 100% shielding effect obtained by using heavy solid and silver plated copper stranded shields. This is the only Firewire and USB cable which is successful in stopping noise interaction between the power and signal lines".
