Ramp up the scale and dynamics from your music, with the AudioQuest Big Sur 20m.

Solid, perfect-surface copper+ (PSC+) conductors
For many years Audioquest has advocated solid-core rather than multi-strand cables. Electrical and magnetic interaction between strands in conventional cables can cause distortion, giving an unnatural edge to the sound quality. The new PSC+ cable takes this one stage further by offering an astonishingly smooth and pure surface. Extremely high-purity Perfect-Surface Copper+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor, reducing harshness and greatly increasing clarity compared to OFHC, OCC, 8N and other coppers.

Double-Balanced Geometry for a more dynamic sound
A big step up from the models below, Big Sur uses asymmetrical double-balanced geometry. Double-Balanced Geometry separates the ground and shield paths. This reduces the cable’s impedance, giving a richer, more dynamic sound as a result.

Cold-welded, gold-plated plugs
By using a high pressure weld rather than solder, there’s less chance of a faulty connection between cable and plug. Not only does this lead to a more reliable connection in the long term but it also ensures low resistance and, hence, low distortion connection for the entire life of the cable.
