OPUS Speaker Cable

Based upon hundreds of hours of listening tests and a large database of performance characteristics of amplifiers, the first OPUS Speaker Cable design was introduced in 2000. The goal was to create a more ideal link between amplifiers and speakers — the most demanding cable design challenge. Since 2000, OPUS Speaker Cable (OSC) has undergone 2 significant technological advances and continues to influence the technology and performance of every audio cable in the Transparent line-up.

Most OPUS owners have spent years assembling and investing in their dream system in a quest to get closer to the music. OSC 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. If you are going to add one cable to your system, start with OSC to get a serious taste of what can happen with OPUS in your system, from feeling and hearing the full power of the orchestra to every nuance of tonal shading and harmonic resolution within the original performance space.

OPUS Speaker Cable is a significant performance upgrade compared to XL Speaker Cable. OSC transfers well-defined bass energy to the bottom of the bottom octave and provides a quieter interface for low-level audio signals than XL Speaker Cable.

OSC 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 OSC manufacturing process which takes several days to complete.

Vibration and resonance control also go to new heights with OPUS Speaker Cable. 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.

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, larger, network OSC module has a low and wide stance on vibration dissipating feet that effectively damp any opportunity for airborne resonances to affect performance.

Please note that your speaker cable runs can be no longer than 25 feet per channel to meet OPUS Speaker Cable design specifications.

OSC must be calibrated to your specific amplifier and be crafted to fit precisely and easily with your specific amplifier, speakers, and system layout. Contact Transparent or a Transparent dealer to share the details of your system components and room layout.

Warranty registration not only extends the Transparent Warranty to 5 years, it provides the original owner with OSC recalibrations at no charge in the event that an amplifier, system layout, or speaker change requires network or configuration adjustments.
