Fractal Speaker Cable
Experience unmatched sound with Townshend Audio Fractal™ Speaker Cables, handcrafted over two days by skilled artisans. Precision-arranged soft copper ribbons, encased in silicone rubber, deliver durability and sonic purity. Unlike mass-produced cables, each custom-made Fractal™ cable features a unique topography and proprietary Fractal™ treatment—a blend of deep cryogenic processing and metal enhancement—for breathtaking detail and clarity. Perfect for high-fidelity systems, these cables rival pricier competitors. Pair with the Townshend Allegri Reference for ultimate performance.
Key Benefits You’ll Love
Unrivaled Clarity:
Fractal-Wire™ treatment and impedance-matched geometry deliver pure, uncolored sound with exceptional detail. “The F1 Fractal removes smudge and dirt from the music.
Lifelike 3D Soundstage:
Closely spaced copper strips eliminate reflections, creating a holographic soundscape. “The layering of the orchestra was precise, with startling clarity.
Tight, Dynamic Bass
Vibration-damped design ensures precise, powerful bass without bloat. “The bass is really tight, precisely formed, with clear attack.”
Universal Compatibility
Non-directional cable with RFI reduction and stable operation suits all amplifiers. Available in custom lengths up to 10m with flexible terminations.
Sizing up
Unlike conventional audio cables, Townshend Audio Fractal™ and Isolda Speaker Cables are impedance-matched, eliminating the need for equal lengths to achieve optimal performance. Traditional non-impedance-matched cables require identical lengths to avoid phase or timing issues, which can waste money and space on unnecessary cable runs.
The Fractal™ and Isolda cables, designed with precision engineering, match the impedance of your speakers and amplifier, ensuring consistent signal delivery regardless of length differences. This saves costs by allowing shorter runs where possible and simplifies setup in space-constrained systems, all while maintaining exceptional clarity, dynamics, and soundstage. For best results, pair with the Townshend Allegri Reference and F1 Fractal™ interconnects.

Why match the nominal impedance of the amplifier to the speakers?
Matching the nominal impedance of the amplifier to the speakers ensures efficient power transfer, optimal performance, and minimal signal distortion. When the amplifier’s output impedance aligns with the speaker’s input impedance, the system delivers maximum power with a clean, undistorted signal, preserving dynamics, clarity, and frequency response. Mismatched impedances can cause signal reflections, power loss, or strain on the amplifier, leading to reduced sound quality, smeared transients, or even equipment damage. Using impedance-matched cables, like Townshend Audio’s Fractal™ and Isolda, further enhances this synergy, ensuring tight bass, articulate mids, and crisp highs for a superior listening experience.

The F1 Fractal Cable, shown as a flat white line, exhibits minimal voltage drop and distortion, preserving signal integrity, while the other cables display erratic, wavy lines, indicating significant reflections due to impedance mismatches

What our customers say about us?
Listening to the LSO recording of the Brahms 2nd Serenade, final movement [LSO Live], it was very clear that the F1’s were providing imaging not previously seen or heard on my system. The accuracy of the orchestra was eerily holographic and seemed to roll out the orchestra in its front-to-back layers in a startling fashion.

Listening to the LSO recording of the Brahms 2nd Serenade, final movement [LSO Live], it was very clear that the F1’s were providing imaging not previously seen or heard on my system. The accuracy of the orchestra was eerily holographic and seemed to roll out the orchestra in its front-to-back layers in a startling fashion.
The Absolute Sound 2018
It rapidly became apparent that what the F1 Fractal were doing was blindingly obvious, and highly significant… the bass was tighter and cleaner, much easier to understand musically, but perhaps the largest difference was the 3-d chiselled soundscape they were creating.
StereoNet 2021
F1 Fractal does extension without the glare that ringing produces, so as long as the source and amplification aren’t producing any nastiness in that area you get sweet, natural highs that reflect those laid down on the tape… It’s not just about fine detail, like Isolda this cable also produces bass that is more concrete and real than anything else I’ve encountered
The Ear
The snare attack that starts She’s Got Her Ticket is sharp and dynamic and very, very clearly a drum with body and presence… I find myself wanting to hear the whole side, and flip it over, and go on and on, more than any time in a long time
Audiogon 2021
It was, without doubt, about the best thing I have ever added to my system. It removed a kind of hash, and the sound had a real body and depth that was previously absent. It is exceptionally detailed but not cold. I cannot recommend them highly enough.

Description
Master Class Dynamic Parallel AC Line Conditioner (MainStream)
Elevate your high-end audio or video system with MainStream, a cutting-edge parallel AC line conditioner designed to banish interference from your home’s power lines. Everyday appliances—refrigerators, air conditioners, washers, dryers—and even external sources flood your AC mains with disruptive RF noise and energy pulses. MainStream tackles this head-on, delivering cleaner power to your components without ever restricting current flow.
Unlike traditional “series” conditioners, MainStream works in parallel—simply plug it into the mains socket nearest your equipment. It filters out interference across multiple frequency bands using a streamlined topology with minimal, high-quality components. No current passes through it, so there’s no limit to how many you can use—perfect for large systems. Say goodbye to hum, hiss, buzzing, or vibrations in your speakers, turntables, or chassis, and banish fuzzy images or moving bars from video displays.
MainStream’s tuned reactive filters target noise known to degrade audio and video performance, reducing system background noise to near-silent levels. Encased in a sleek, milled aluminum housing with a subtle blue glow to signal operation, it’s built for a lifetime of reliable service.
