Audioquest Irish Red 2m Subwoofer Cable RCAs (Singl Solid conductors eliminate strandinteraction distortion and reduce jitter. Solid silverplated conductors are excellent for very highfrequency applications. These signals, being such a high frequency, travel almost exclusively on the surface of the conductor. As the surface is made of highpurity silver, the performance is very close to that of a solid silver cable, but priced much closer to solid copper cable. Any solid material adjacent to a conductor is actually part of an imperfect circuit. Wire insulation and circuit board materials all absorb energy (loss). Some of this energy is stored and then released as distortion. Irish Red uses airfilled FoamedPolyethylene Insulation on both conductors because air absorbs next to no energy and Polyethylene is lowloss and has a benign distortion profile. 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. Identical + and  conductors prevent the shield being used as an inferior audio conductor. 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.
