MEXCEL has a single goal: To master new and unprecedented territory for audio cables. Since its appearance in 2004, MEXCEL brought major innovation to the field of audio cables. Mitsubishi Cable Industries, developer of cables for the aerospace and defense industries, teamed up with audio cable specialist ACROLINK for this endeavor. Joint development by those two companies and ESOTERIC has given birth to MEXCEL cables delivering flat transmission characteristics with a wide frequency range going beyond the gigahertz frequency zone. The tremendous information volume carried by gigahertz frequency zone transmission has combined with high-purity 7N Cu (99.99999%) to unleash the potential of audio systems, transcending established concepts for analog and digital transmission cables.
Now the fourth generation of MEXCEL cables is here as the result of our quest for a ultimate musical expression. We have now reached a new milestone with products destined to spur a tide of change never before seen in the history of audio cables.

Gigahertz Level Flat Transmission

A megahertz is ten times larger than 100 kilohertz, and a gigahertz is a further 1,000 times larger, so 1 GHz is 1 billion Hz. At the gigahertz level, extremely accurate waveform transmission without corruption to the signal waveform is possible in digital transmission. Even in analog transmission, flat frequency response can be achieved in the entire audible range.

99.99999% Purity “Stressfree” Processing

As the main conductor, MEXCEL series cables incorporate D.U.C.C.* 7N Cu developed by Mitsubishi Cable Industries. With 99.99999% purity, controlled in a base material production process equivalent to that used for semiconductors where high-level quality assurance is demanded, total metallic impurities are kept to less than 0.1 ppm. With respect to crystalline structure deterioration caused by bending when in use, excellent transmission characteristics are maintained using special “Stressfree” processing developed by ACROLINK for self-annealing at room temperature to preserve the optimal crystalline condition.
* D.U.C.C.: Dia Ultra Crystallized Copper (D.U.C.C.) is a high-purity copper conductor material developed by Mitsubishi Cable Industries. Its crystal grains are grown to many tens of times larger than those of ordinary pure copper, and the crystalline lattice is given unified directionality. The larger the crystal grains, the smaller the crystal grain boundary (boundary between individual crystals), thus providing greater benefit in terms of sound quality.
