Solid Long–Grain Copper (LGC) Conductors - Solid conductors eliminate strand-interaction distortion. Evergreen's solid Long–Grain Copper allows a smoother and clearer sound than cables using regular OFHC (Oxygen–Free High–Conductivity) copper..
Foamed–Polyethylene Insulation - Tower uses air–filled Foamed–Polyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is low–loss and has a benign distortion profile..
Metal–Layer Noise–Dissipation System (NDS) - 100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment's ground reference requires AQ's Noise–Dissipation System. Noise–Dissipation System prevents a significant amount of RFI from reaching the equipment's ground plane..
Asymmetrical Double–Balanced Geometry - While many single–ended cable designs use a single path for both the ground and the shield, Double–Balanced designs separate the two for cleaner, quieter performance..
Cold–Welded Gold–Plated RCA Plugs - This plug design allows for a connection devoid of solder, which is a common source of distortion. Because the ground shells are stamped instead of machined, the metal can be chosen for low distortion instead of machinability..
