It is impossible for an interconnect cable to improve the sound of a CD player beyond its inherent capabilities, although a good cable will of course let more of its ability through, a poor one will hold back the product's performance. We find its more of a fine tuning exercise, the same as putting better quality HT leads under the bonnet of your car. It can have a dramatic impact on the overall performance of your hi-fi or AV system.

And cables do make a difference - in general terms the more expensive a cable the better will be the purity of the copper (or whatever) in its conductors, and thus the easier it will be for signal to get through. And it's not just copper: some exotic cables use silver or even titanium for their conductors, while a few wires from van den Hul, for example, use carbon fibres rather than metallic cores!
With all this choice, how do you choose? we offer a home trial service for some of our cables, and are able to give honest advice on which cable you should try with your system.
