Ultimate Reference Helix is our flagship consumer series product. These products are for audiophiles looking for the utmost in clarity. Helix delivers our highest level of Magnetic Conduction Technology, in a relatively compact unit with demonstrative power.

Helix technology is the magnetic system implemented in this series. The Helix properties are similar to the basic magnetic techniques applied to the Pro and Pro Elite series. At the core of Helix technology, you will find gold-plated spherical magnets. These are used in conjunction with magnetic cylinders to center the lines of flux within the magnetic pack. The closer these lines, the more exact the electron flow. This phenomenon helps to greatly reduce the distortions that arise from electron scattering. Electrons scatter for various reasons. Typically electrons prefer to remain on the outside of the conductor. Helix technology forces these electrons into the center of the conductor. High Fidelity Cables designs fundamentally change the direction of the electron itself. Electrons are forced to the middle, instead of the outside of the conductor, unlike what is seen in a traditional conductor. By utilizing these high-tech magnetic spheres, Helix technology is able to even further lower distortion.

>Patented Silicone damping system: Each magnetic waveguide is floating in a viscous silicone gel. This gel works in conjunction with the varying sizes of magnetic cylinders. The varying shape and size of each cylinder allows for a greater surface area to be covered, and in turn an improvement in reducing vibrations.

To give an example, the effects are much like a tightened string between two tin cans. The tension and predetermined pathway conduct signal more efficiently. But to clamp the string with an external force would greatly reduce the vibrations traveling in the string. Vibrations following the audio line can be reduced with our Patented Technology (US Patent #9631691).

An even greater impact is made by using silicone to dampen vibration. The silicone adheres to the face of the magnets as well as to the sides of the magnets. Helix design by nature exposes a greater magnet surface area for dampening while keeping a precise conduction point. When utilizing helix spheres, almost the entire surface is covered by the dampening system.

Alternating current has a spinning magnetic wave, caused by the electromagnetic B-field that surrounds the wire. It spins back-and-forth at 60 cycles per second. This causes induced vibration on to A/C. This vibration, if not removed, follows the signal path and is just picked up as a harmonic, not unlike the harmonics from electron tubes, cartridges, and tonearms. By removing this distortion we can obtain a silky smooth liquid and natural sound.

Ultimate Reference Helix is an advanced technology to improve your audio system. With High Fidelity Cables design it can be applied as easily as putting a cable in your system.

Digital cables are certainly one of the most important cables in an audiophile's system. They can help bring much more out of a audio system and contribute to better sound quality in a major way. And that critical link can be every bit as important as the DAC itself.

High Fidelity Cables digital cables with Magnetic Conduction are at the pinnacle of digital cables and offer unbeatable realism, clarity, dynamics, impact, and detail. They help greatly in improving sound staging and imaging.

Generally speaking, audiophiles looking to upgrade a DAC find more improvement from a HFC digital cable than most DAC upgrades can offer. Don't overlook this critical cable, it is important to get the best one your budget will allow.
