About Supra Cables
Quick Access
Swedish engineering, published specifications, sensible prices
Supra have been making cable in Sweden since 1976, and the company's character is easy to describe: everything is specified, nothing is mysterious, and the prices are lower than the engineering warrants.
That last point is the reason they get recommended so often. A Supra speaker cable or LoRad mains cable will publish its conductor size, its construction, its capacitance and its compliance with Swedish and European electrical standards. There is no story about proprietary metallurgy, and there does not need to be one, because the construction is good and the specification says so.
The LoRad mains cables are the range we sell most of. They are properly shielded, correctly rated and available made up or by the metre with Supra's own plugs, which makes them one of the few straightforward upgrades in the mains category.
The Cat 8 network cables have found their own following for the same reasons: solidly built, fully specified, and priced so that trying one is a small decision.
Supra also make an unusually wide catalogue of general-purpose cable, which is useful when a job needs something specific rather than something premium.

LoRad covers the mains cables, Ply and Classic the speaker cables, and EFF-I the interconnects. Most Supra cable is available made up or by the metre with their own connectors.

In this way, you can play your music stored on your computer or mobile phone/tablet or media player, via your hi-fi system (if the aforementioned DAC is connected to an audio input of your stereo system).
