Oxyfuel RCA Interconnect

Oxyfuel RCA Interconnect


Zu Audio Oxyfuel delivers on its promise of high value. It is a pure, stripped down coax design featuring a large diameter, pure copper deposit tubular outer conducting path for signal, micro-cellular foamed PE dielectric with a bonded high conductance, low magnitude aluminum shield. If you are looking for an audio, analog or digital, coaxial interconnect that really will improve the fidelity of your system and don’t need fancy hi-fi salesmanship, slick packaging, or foo dust the Oxyfuel is your cable. Yes, it is stiff, but you can bend it into position without risk of harming performance or durability.

OxyFuel Direction of Signal Propagation

Oxyfuel 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. “Oxyfuel” 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. 


Oxyfuel 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.

Oxyfuel Maintenance

No maintenance is required for the cable or the connector. The connectors on Oxyfuel are heavy gold plated, high copper brass alloy. They are very unlikely to ever need cleaning. Regarding contacts generally however, we offer the following information.

If the contacts of any connector become dull or tarnished you will need to clean them. This is likely to never be a problem with nickel, gold or rhodium platted connectors. Pure copper or silver contacts that are not plated may require cleaning. If your connector contacts are nice and bright, don’t worry about it; and the only time you need to check them would be if you disconnect the cables. In fact, anytime you are making an electrical connection make it a habit to inspect the contacts and clean them if they are tarnished or dirty.
