LFD AUDIO: Q/A with Dr. Bews. Cable evolution

What can you tell us about cable evolution at LFD please?

Over the past 5 years I’ve been experimenting with different diameters of silver, which form a multistrand conductor. Although this method has been tried with copper, e.g. Cardas, Van den Hul, and others, I believe that silver is better, because it possess better purity and transparency compared to copper.

Essentially the composition and number of different diameters of silver within the multistrand give rise to the overall subjective “frequency response” and “time response”. I suggest you think of each different diameter of silver as a bandpass filter, and the overall response is formed from the combination of each of the separate filters. The trick is to make sure that the overlapping between successive filters is correct, which subsequently dictates the exact diameter of each strand of silver chosen.

As the experimentation progressed, it became apparent that the sound became better as the number of diameters increased, which dictated that the difference between each of the diameters reduced. This is a very labour intensive job, but now we have a formula to determine the size of each strand within the multistrand. If this experiment was only to enable the manufacture of neutral sounding cables. then really it would be a waste of time and money.

But what seems to happen subjectively, as the number of strands increases, is that more detail is revealed in a very natural manner, because time smearing seems to be greatly reduced, so giving greater separation of instruments and vocals. Currently, our best cable uses 23 strands of silver possessing 19 different diameters.
