The Furutech Flux Series Cables Review
Set Up and Listening

The last cables to be installed in the system were the PowerFlux power cables. They may have the most technology of any of the cables under review. This is no surprise, given Furutech’s expertise in power distribution. The PowerFlux uses 68 strands of Alpha OCC twisted around μ–conductor strands with a special grade PE dielectric. Alpha conductors, by the way, are fine OCC wire treated with Furutech’s Alpha Cryogenic and Demagnetizing process. The dielectric is surrounded by an inner sheath of RoHS compliant PVC incorporating carbon powder, which is then covered by a full α Alpha conductor wire braid shield.

These power cables use Furutech’s Piezo Ceramic Series connectors. The FI-50 series connectors are very expensive too, and some of the most impressive I have come across. According to Furutech, the connector housings are made of, "multiple layers of carbon fiber in a damping and insulating acetal copolymer, surrounded by nonmagnetic stainless steel bands. The connector bodies combine two 'active' materials: Nano-sized ceramic particles and powdered carbon. Nylon and fiberglass are incorporated as well forming an extremely effective, mechanically and electrically non resonant connector body."

I installed four PowerFlux power cords throughout the system. I can safely say they were responsible for the single biggest leap forward in the performance of the system overall. I have a dedicated line, and Audience power conditioners, and some pretty good power cords from Acoustic Zen, Mojo Audio, Shunyata, and Element Cable. The PowerFlux was at another level completely. And it since it costs ten times more than the most expensive power cord in my system, maybe this is what I should have expected.

Specifically, the PowerFlux loom added clarity, speed, and refinement to the system that no other set of power cables was able to match. The PowerFlux cables were used on a variety of tube and solid state components and, without exception, it brought each component to a new performance level.  Since the cables I received were already well burned in, the effects I heard were pretty immediate.  

It came to the point that I was not looking forward to removing the cables from the system, but alas, there was no getting around it. The cables were needed for duty at a trade show, and my bank account was not worthy of purchasing them outright. It must be noted that Furutech has several less expensive tiers of cable, engineered to perform at very high levels, for those with more modest budgets.


Furutech PowerFlux

With the whole system linked with Furutech cabling, there was a distinct synergy. It is often said the best cable is no cable at all, and I agree. Since we must use cables, we try to seek out the ones that do the least amount of harm and don’t impede the flow of information from component to component, component to speaker, and wall socket to power supply. Furutech, in my experience, has hyper-engineered some of the best cable solutions I have ever heard. They do this with superb materials, build quality, ultra pure conductors, and other proprietary technologies. Their connectors are even sought out and used by other cable manufacturers, which certainly says a lot.

These are not inexpensive cables. For those who have invested significant sums into room and systems, I can’t recommend an audition of the Furutech Flux series of cables any stronger. They will be commensurate with the very best components and speakers out there, bar none. If you can stretch your budget to afford these cables, give them a listen. The pride of ownership, build quality, and sonics are off the charts.
