AudioQuest Tower 3m RCA Analog Audio Interconnect Cable SOLID LONGGRAIN COPPER (LGC) CONDUCTORS - Solid conductors eliminate strandinteraction distortion. Tower's solid LongGrain Copper allows a smoother and clearer sound than cables using regular OFHC (OxygenFree HighConductivity) copper. OAMEDPOLYETHYLENE INSULATION - Tower uses airfilled FoamedPolyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is lowloss and has a benign distortion profile. METALLAYER NOISEDISSIPATION SYSTEM (NDS) - 100% shield coverage is easy. Preventing captured RF Interference from modulating the equipment's ground reference requires AQ's NoiseDissipation System. NoiseDissipation System prevents a significant amount of RFI from reaching the equipment's ground plane. ASYMMETRICAL DOUBLEBALANCED GEOMETRY - While many singleended cable designs use a single path for both the ground and the shield, DoubleBalanced designs separate the two for cleaner, quieter performance. COLDWELDED GOLDPLATED 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.
