Kimber Kable DV30 Digital Interconnect
RG6 based high purity copper and foamed PTFE dielectric offer increased bandwidth over the V21. Longer lengths are no problem for DV30.
DV-30 is a super high performance optimized 75 ohm RG6 type cable. It is superior to the V-21, serving as both an excellent digital cable and also a high-quality digital cable. The center conductor is pure solid core copper and insulated with a foamed Teflon dielectric.
Low loss fluorocarbon dielectric
Nitrogen assisted hand soldered termination
In the mid ’70s Ray Kimber worked at a sound and lighting company in Los Angeles. The first big discotheques were being installed at that time. Traditionally sound and lighting systems were not installed right next to each other, nor did lighting systems ever have such an array of noise generating fixtures, such as strobes and other flashing and dimmable lights. But in a discotheque the lights and speakers are installed next to each other. The speaker cable was acting as an antenna array and bringing noise from the lights into the sound system.
In an attempt to solve the problem they encased the speaker cable in a steel conduit. This did help with the noise, but it also had the unintended result of lowering the fidelity of the audio. This happened because the steel conduit interacted with the magnetic field of the speaker cable.
Ray had the idea of some counter-rotating sets of conductors to cancel the magnetic interaction effect, but then also surmised that the counter-rotating sets of conductors would likely not pick up noise even without the conduit. He was correct, the noise was greatly reduced! But, Ray was also quite surprised at the difference in perceived audio quality. It was that discovery of noise elimination and improved fidelity that set him on the path to develop cable designs.
To his great satisfaction the finalized version of his braided wire concept not only rejected the (RF) noise, but allowed the system to sound different, better. It was after this period of discovery that Ray decided to take a risk and began entertaining the idea of selling his new discoveries.
