Purist Audio Design Neptune Bi-Wire Diamond Speaker Cables

Purist Audio Design's Diamond Revision Neptune Cable line is the pinnacle of our Fluid shielded cables! Every cable in the Neptune line utilizes our improved proprietary Fluid dampening. Our Fluid dampening has long been a favorite of audiophiles for years delivering a warm sound with exquisite mid-range. The speaker and bi-wire cables are crafted around 7 AWG single crystal copper stranded conductors. Neptune cables deliver a larger soundstage over the Venustas cables with stunning detail in the mid-range! The cables can deliver such impressive musicality, they keep the listener immersed in the music!

The audiophile aims for the highest quality and best sound possible. We offer the Neptune line in two different configurations, with customization available upon request:

These speaker cables come in a four (4) cable set, with an individual positive cable and individual negative cable for each channel.
