Perfect-Surface Copper+ (PSC+) has an astonishingly smooth and pure surface. Proprietary metal-processing technology protects the wire's surface at every stage of drawing and fabrication. When high-purity low-oxide copper is kept as soft, pure, and smooth as possible, it becomes a wonderfully low-distortion PSC+ conductor. PSC+ is manufactured by applying the same exceptional technology to an ultra-pure copper+ metal blend incorporating a small amount of ultra-pure silver. The resulting sound quality is even more remarkable.
All drawn metal strands or conductors have a non-symmetrical, and therefore directional, grain structure. AudioQuest controls the resulting RF impedance variation so that noise is drained away from where it will cause distortion. The correct direction is determined by listening to every batch of metal conductors used in every AudioQuest audio cable. When applicable, arrows are clearly marked on the connectors to ensure superior sound quality.
The carbon-loaded extrusion covering the PSC+ conductors provides an additional layer of RF noise rejection. This conductive layer helps dissipate high-frequency interference before it can affect the audio signal, ensuring cleaner sound reproduction.
AudioQuest's 500 Series connectors feature Hanging-Silver plating over Purple Copper for superior conductivity and corrosion resistance. The direct-silver plating is optimized for sound quality, while the design ensures secure, reliable connections that maintain signal integrity.
These jumpers are designed for speakers with bi-wire terminals (dual binding posts for high and low frequencies). The spade to banana configuration allows flexible connection options depending on your speaker cable terminations and speaker binding post preferences.
