Long Grain Copper (LGC) Conductors

Long Grain Copper (LGC) has fewer impurities and fewer internal grain boundaries, which reduces distortion and digital timing errors.

Hard Cell Foam (HCF) Insulation

Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy. Some of this energy is stored and then released as distortion. Hard cell foam insulation is similar to the foamed PE used in our more affordable Bridges & Falls cables, and is injected with nitrogen to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy into the conductor, distortion is reduced. Additionally, the stiffness of the material allows the cable’s conductors to maintain a stable relationship along the entire length of the cable, producing a stable impedance characteristic and further minimizing distortion.
