What makes it so good?
Ray Kimber famously discovered the sonic advantages of crossing wires when he was installing discotheque sound and lighting rigs in the 1970s. He found that the speaker cables were acting as an antenna for noise generated by the lighting and that this noise was then being injected into the sound system. One existing option was to encase the speaker cable in a metal conduit. This helped reduce the noise but also had the unintended consequence of lowering the fidelity of the audio, as the steel was interacting with the magnetic field of the speaker cable.
Ray initially surmised that the solution to this issue could be to use counter-rotating sets of conductors to cancel this magnetic interaction effect, but then also considered that the counter-rotating sets of conductors may not pick up noise even without the conduit. He was correct, the noise was greatly reduced!What did surprise him, though, was that the final woven design was so effective that not only did it reject RFI but also had a significant effect on perceived sound quality. It was this discovery that convinced Ray to develop the cable specifically for the audio market.
Over the years this woven design has formed the basis for a whole range of Kimber Kables and is the core principle that runs throughout. This means that, although 4PR is at the start of the range, its basic design is, in essence, the same as that of the range-topping Select speaker cables. That’s why it has remained in the range for all this time; simply because that woven principle is just as effective today as it ever was, and that means 4PR represents outstanding value for money.
A high end starter cable?
When you buy 4PR you’re buying into a cable geometry that’s unique to Kimber Kable. That’s why we say that 4PR really is a budget high-end cable.
Because of the unique way it works, it brings a musical quality that cannot be replicated by standard cable designs. It is not at all unknown for owners of high quality systems to buy 4PR as a first dip into the waters of audiophile-quality speaker cable and the hang onto it simply because it sounds so good. Does that mean there’s never any reason to move from 4PR? Of course not. As you move up the range, you’ll benefit from the use of better materials and additional conductors. But it does mean that, no matter what level of system you own, 4PR will never disgrace itself.
The long term performer
33 years after its introduction, Hi-Fi Choice magazine gave their award for Best Speaker Cable to 4PR, stating that "For sheer musical enjoyment, no other cable tested this year is on a par with the 4PR"; no mean feat for the old guy! A year later, it also won their group test with the comment that the cable featured “many high-end virtues at a budget price, including lovely detail and very well-judged bass, plus sweetly extended treble”.
A first step
If you are yet to try Kimber speaker cable in your Hi-Fi, this is the perfect place to start. It’s an ideal partner for amplifiers from the likes of Arcam, Cambridge Audio, Cyrus, Naim or Audiolab – amongst many others. All of these have the potential to present a very musical performance and 4PR will help to release this. 4PR is suitable for both standmount and floorstanding speakers, though you’ll find the latter would benefit even more from the additional conductors found in 8PR if they are larger models (the doubling of conductors will help to move those larger drivers more efficiently). 8PR’s additional conductors are also advantageous if you have longer runs of cable between your amp and speaker.
