How can we connect the cables directly to the connectors without letting the current go through solders, brass and platings? Our answer is two piece machined soft plastic plugs. These plugs deliver the least colorations and the fastest speed.

Newly designed solid-core copper wire. Sufficiently thin solid-core single strand wire without plating. These are the necessary and sufficient requirements for a conductor suitable for audio cables. In other words, other characteristics do not matter.
The wire used for 'STRATOS' is a single strand of 0.4 m/m solid-core OFC copper wire. In combination with light and flexible tubing, this cable has a sensitive response to the rise and fall of signals, with uniform, even speed from the bottom end to the top end of audio frequency.

With this kit, you can make interconnects and speaker cables for whatever the length that suites your system. All you need is a wire-stripper (or something to strip the jacket off).

As an interconnect cable, with any components with RCA connectors. As speaker cables, between any amplifiers and speakers.
Do not use them as power cords!
