FFT. The previous page went live in June 2020 then on lengthy hold. It wasn't until November that FFT changed from the fast Fourier transform algorithm to Force Field Tech. When paused for a screen capture, a Vimeo promo video on their site revealed…

… this blurry image to recognize a PCB with a few chips on it for a vague notion about the case's guts. We do know that a universal 5V supply powers it and that it's not the outer spiral-wound extra conductor of certain models which plugs into it since others without that conductor can accept it as well. In the meantime I'd reviewed the BOP Quantum Field product from South Korea. It works on any cable including analog/digital signal but was quite tweaky and certainly costly in use. Elsewhere Telos had announced their own Quantum Active Cable.

In short…

… the notion that conventional shielding is no longer sufficient to protect our costly systems from ever worsening ultrasonic radiation seems to be catching on. Now different designers pursue apparently related but independently arrived-at ways to add active shielding to their cables. Claiming exclusives here already seems bygones.

What would the IRA have to say on the subject in the listening chair? At £250 per FFT, not only is this an easy retrofit if finances don't allow so from the start. It's relatively modest in the high-end scheme. If one runs multiple such cords, it's child's play to move the module from one component to the next without powering anything down to learn where this active shield works best. And, the audiophile police just read 'universal 5V supply'. They and I—busted: I too am an audiophile worrier—suspect a switching wall wart. Won't that inject its own noise into the very power line this tech purports to protect against high-frequency hash?
