Firemine S/PDIF

from 99.00

Designed specifically for S/P-DIF digital audio transmission—and of course it does an amazing job, and for less than the rest. Inner conductor is a high conduction copper deposit, which despite its large diameter (roughly 18 AWG), has a very low conducting area as the conducting material is deposited on a core. Results of this process are: unprecedented precision, excellent durability and efficient/repeatable manufacturing—Firemine is a truly excellent performance to cost digital audio cable. It is on the stiff side but, you can bend it into place without fear of damaging the cable or its performance.

Proper 75 ohm signal to ground spacing and dielectrics; a simple combination of common stock polyethylene and a proprietary catalyst which produces a micro-cellular foam. The combination of materials and processes yields a very uniform density dielectric. Standard foamed dielectric processes produce a medium with much larger cells with much thicker cell walls, and radial density variance. These inconsistencies in the dielectric mess with impedance and reduce stand-wave ratio performance.

Two shields: one, a foil bonded directly to the dielectric achieves 100% area shielding, ultra low mass, and characteristic impedance uniformity. The second is an aluminum braid that provides the high magnitude shielding component.

Firemine Direction of Signal Propagation

Firemine is not a permanently directional cable. It can be used in either direction. However, we pay close attention to direction of manufacture of all points, and identify this by placing the labels at the source end, with the text reading in the direction of recommended signal flow. “Firemine” as printed would read away from the source (transmitter), toward the load (receiver). Example: player > preamplifier. Connecting it with the labels at the source ensures matching channel fidelity, increased burn-in speed, and allows the user to easily identify direction after cable or gear swapping. 

Burn-in

Firemine will require some play before it’s fully burned in, roughly 200 hours. We do not recommend any burn-in devices or special recordings. We do recommend music you enjoy, preferably upbeat full spectrum recordings. Rock, roots, full orchestra, most film scores, big band.... For the possible how and whys about burn-in please see our Answers section.

Firemine Maintenance

No maintenance is required for the cable or the connector.
