We produce two types of connectors: "banana" and "spade". But our experience shows that banana is more comfortable, and the sound is not inferior as "spade" connectors. Therefore, for the speaker cables, we recommend "banana" connectors.
In entry and standard level cables we use a gilded brass. In premium level cables we use only high quality copper plated with pure gold thickness of 7 and 10 microns.
All our plugs are produced in Taiwan as per our own specifications and designs. Contact parts are mostly made from high quality gold or rhodium plated copper. The bodies of the connectors are made from brass and copper alloys with different types of plating (special lacquers, gold or rhodium). These are high quality high-end plugs.
