Transparent Magnum Opus Speaker Cable

MAGNUM OPUS Speaker Cable is designed to mate with the finest amplifiers and speakers ever made. It works well with other TRANSCENDENT Transparent System Companions in the best systems to lift the listener effortlessly out of his or her listening seat to the best seat in the concert hall. When the goal is no-compromise performance at the absolute highest level, MAGNUM OPUS Audio Cables will ensure that your system can take you there.




Based upon thousands of hours of listening tests and a growing database of performance characteristics of amplifiers over a period of more than 20 years, MAGNUM OPUS Speaker Cable (MOSC) made its debut in 2014. The goal was to surpass the performance of OPUS Speaker Cable and create an even more ideal link between amplifiers and speakers — the most demanding cable design challenge. MAGNUM OPUS SPEAKER CABLE is handcrafted in the USA and has set a new standard and continues to advance the state of the art for all products in the Transparent line-up, including the original flagship OPUS Speaker Cable.

Most MAGNUM OPUS owners have spent years assembling and investing in their dream system in a quest to get closer to the music. MAGNUM OPUS Speaker Cable is the linking solution to help dream systems deliver upon their promise of thrilling “you are there” listening experiences every time you press “on” and cue up your favorite source material. All network components are matched and measured at the edge of what technicians can control in production. MOSC reveals the full potential of the best amplifiers and speakers in the world.

If you are going to add one cable to your system, MAGNUM OPUS will give you the most commanding taste of what your system is capable of achieving from feeling and hearing the full power of the orchestra to every nuance of tonal shading and harmonic resolution within the original performance space. It also transfers well-defined bass energy down through the bottom octave and provides a quieter interface for low-level audio signals than OPUS Speaker Cable.

Network components are also specifically chosen and matched more closely to suit the electrical characteristics of the cable and its length, and the network itself is calibrated more precisely to the electrical output characteristics of your phono cartridge. This extra level of precision adds considerable time to the painstaking manufacturing process which takes several days to complete, but it’s worth it. From feeling and hearing the full power of the orchestra to every nuance of tonal shading and harmonic resolution within the performance space, MAGNUM OPUS Speaker Cable is the vehicle to help transport you to another musical place and time. Rendering the musical space of the original performance upon a black, silent background melts the noise and distractions of the day away.

Vibration and resonance control also go to new heights. The components that comprise each network are encased in electrically neutral epoxy and then surrounded by a massive carbon fiber network housing that has been contoured specifically for the purpose of reducing standing wave reflections. Carbon fiber is nonmagnetic, light, and stiff. The thinner, stronger network housing provides a large cavity for damping epoxy loading, and the non-magnetic qualities of carbon fiber allow the free and full expansion of electromagnetic fields thereby freeing your system to reveal micro dynamics and harmonic music information more accurately.

A thick carbon fiber sheet embedded in epoxy resin further stiffens and damps vibrations in the custom-machined, constrained-layer damped acrylic carapace platform. Isolation feet stabilize the carapace platform and also reduce resonances and vibrational interference. Acrylic platform fasteners have a specific torque pressure and bore deeply into the epoxy-loaded carapace to cancel any residual resonance and vibration.

Gold plated, solid tellurium copper connectors are customized to your amplifier and speaker terminations to make superior contact and transfer power more efficiently. The heavier, wider, and longer MAGNUM OPUS Speaker Cable network module has a low and wide stance with a significant amount of mass positioned directly over vibration dissipating feet to more effectively damp any opportunity for airborne resonances to affect performance.
