What do Supra do?

They design their own cables in their own production

All of our soldering team are holders of soldering certification to Military Quality Standards

Directionality Assurance
All Supra cables are constructed with attention to consistent and equal ‘direction’ in all the conductors. Simplistic electronics theory says there is no ‘directionality’ in conductors, but assumes conductors are perfectly isomorphic. It also ignores the inherently directional nature of signal and energy flow. Yet electricity could not be sold without ‘energy flow directionality’.

They use huge machines to produce exactly the right product for a particular use.

They export to 38 different countries around the world.

And with over 30 years of production history and experience, you can be sure that they are doing a lot of things "just right".
