There is a bewildering array of interconnects available on the market from cheap to exhorbitant prices. Good interconnects are important, there's no point in having high quality equipment connected together with cheap cables that don't allow the full frequency range to pass through unaffected.
You can make up your own high quality interconnects using the cable and connectors in this category. It is particularly useful when you want cables of a particular length that's not a standard size, or using connectors that are no longer readily available like DIN. However, please also check out the Interconnects sub-category in Hi Fi Accessories as you might be surprised just how inexpensive some of the ones we offer are.
