Domination of solid single track cable

Most speaker cables on the market consist of a multi-strand wire conductor which is made by many twisted thin wires. (Also Litz type speaker cable is made up of a group of multi-strand wire conductors)

Due to stranded wire conductor being flexible and easy to use, most speaker cables on the market are made with a stranded conductor, however, multi-strand and Litz type wires generate stray current called “Strand jump phenomenon”.

This straying current causes incidental sound and distortion in the signal transmission and is the cause of impurities and gradation of sound.

SPC-REFERENCE uses a solid single-core structure in which the straying current is not theoretically generated.

This allows a signal transmission extremely faithful to the original source without the incidental impurities in sound and distortion.

In addition, flexible handling is achieved, by examining and improving the cable structure closely, we also achieved excellent flexibility.

Air Insulation

We were able to implement air layers by installing dummy tubes, thus improving the conductivity and reduce vibration.

The conductors are virtually floating with six thick and thin dummy tubes. This also creates an excellent shielding effect, a superior dielectric constant and vibration control, giving optimum conductivity and a high quality, full-bodied sound.

100% shielding with a copper foil

SPC-REFERENCE is equipped with a copper foil shielding for a 100% shielding effect.

Most ordinary speaker cables do not have any shielding, or they use mesh type shielding.

The mesh type shielding is full of open spaces and is unable to completely eliminate noise. Furthermore, the meshed shielding itself generates stray current which reduces the sound quality.

Also, shielding with aluminum foil or magnesium foil is not effective for the audio frequency range, this type of shielding pollutes the sound with the materials own characteristics.

Copper foil shielding is the most effective for the audio frequency range. This creates a superior signal transmission with high S/N ratio.

Tourmaline containing sheath

The outer sheath of the SPC-REFERENCE contains natural tourmaline powder.

Tourmaline is an ore with slight potential which generates negative ions with an external stress such as electric current or vibration.

SPC-REFERENCE can avoid electrical and transmission losses by generating negative ions itself when an electrical signal is passed through the cable.

We have a clear and pure sound with a solid single-core conductor. An open and vast sound stage is created by the air-insulation, full-bodied and superior tone created by the tourmaline sheath.

The Cost to Performance ratio is simply superb.
