Designed for audiophiles

We audiophiles are a discerning crowd, and have very high expectations for premium power cables. We demand the lowest noise floor possible, increased resolution, deeper, tighter bass, improved soundstaging, enhanced imaging, and above all... musicality. These attributes must also accompany rugged construction, reasonable flexibility, and a tight, secure connection. These are the conditions for how Furutech’s Alpha PC-Triple C conductor was conceived: specifically for audiophile use and developed to deliver the purest power transfer possible.

The precision of a Samurai sword

The Samurai knew a thing or two about precision engineering: few would argue against the brilliance of the razor-sharp technology of the katana, the Samurai sword? Key to this craftsmanship was a forging process that involved many successive rounds of metal folding. Furutech’s Alpha PC-Triple C conductor mirrors that technique, using an ingenious, proprietary forging process whereby variable high pressures are applied to high purity oxygen-free copper. This process essentially 'folds' the copper conductor tens of thousands of times in this virtual forging process. The copper crystals' grain boundaries are thus transformed and realigned from a vertical direction into a longitudinal orientation. The end result allows the electrical signal to flow in a manner that is sonically more optimal for audiophiles. The copper's crystals become uniform and consistent both physically and electrically, which enhances conductivity vs a typical conductor.

The result of this process is a cable that is free of amusical artifacts and impurities, delivering a more compelling listening experience. As a result, you can expect to hear a number of important improvements:

• A lowered noise floor, allowing more amphasis on the music flowing through your system.
• Greater resolution and inner detail, letting you hear even more deeply into your most loved recordings.
• Tighter, more controlled low frequencies, with more realistic textural information.
• Cleaner, clearer highs with almost unlimited extension for today’s high-resolution recordings.
• Greater image focus, with a more precise and realistic reproduction of the soundstage, and venue information.
• An increase in both macro and micro dynamics, throughout the entire audible frequency range.

Is it really possible to hear such differences from a power cable? Absolutely. Experience the difference for yourself: Replace your existing audiophile power cables with the Furutech FP-TCS21 or FP-TCS31 Triple C bulk power cable and you’ll feel closer to your music than ever before. Or add them to your home theater system for sharper, clearer video images and truer colors.

The Alpha PC-Triple C forging process at a glance

Step 1: High purity OFC undergoes variable high-pressure forging and folding

Crystal grain boundaries are in all directions, not allowing smooth signal transmission. Continuous transport forging elongates the crystals… …until the crystals form a longitudinal direction allowing for smooth signal transmission.

Step 2: The fixed-angle continuous transport forged conductor is then subjected to further a elongation and pressing process to create the super-fine conductors. The conductors then go through a time and temperature annealing process which fuses the crystals to each other. The finished conductor is now Alpha PC-Triple C.
