Monocrystalline

What exactly is this? At Japan's Chiba Institute of Technology a special casting process was developed by Prof. Ohno, which enables a cable extrusion resulting in a very long single crystal silver wire.

Silver

High-purity silver is the metal with the best conductivity. Ordinary silver cables are known for airy openness but also having a distinct, slightly a bright character. A significant reason for this tendency is the fact that these cables basically consist of small crystal pieces, apporoximately 10mm in length, connected to each other. So in 1m of cable there are about 100 “connections“ that have to be crossed, and the delicate music signal is not able to pass through smoothly. Furthermore, these connections are prone to corrosion and the effects of aging, which may cause the sound quality to gradually decline.

Mono Crystal

Monocrystalline cables are different, because they virtually consist of a single crystal. The ensuing lack of “internal connection impedance” has a very positive tonal impact. Profound transparency combined with perfect balance allows music to breathe.

Obviously, monocrystalline silver can not be cheap due to its time-consuming, patent-protected manufacturing process with low throughput, offered only by very few licenzed manufacturers - and the choice of material.
