SEMI-SOLID CONCENTRIC LONG-GRAIN COPPER (LGC) CONDUCTORS In a conventional multi-strand cable, distortion caused by electrical and magnetic strand interaction is compounded as each strand changes position within the bundle. In an AQ Semi-Solid Concentric cable, strands within the bundle maintain their fixed relationships, significantly reducing distortion. Long-Grain Copper (LGC) allows a smoother and clearer sound than cables using regular OFHC (Oxygen-Free High-Conductivity) copper. LGC has fewer oxides within the conducting material, less impurities, less grain boundaries, and definitively better performance. HARD-CELL FOAM INSULATION Hard-Cell Foam (HCF) Insulation ensures critical signal-pair geometry. 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 nitrogen-injected to create air pockets. Because nitrogen (like air) does not absorb energy and therefore does not release any energy from or into the conductor, distortion is reduced. In addition, the stiffness of the material allows the cable's conductors to maintain a stable relationship along the cable's full length, producing a stable impedance character and further minimizing distortion.
