Neptune Speaker Cables

Purist Audio Design's newest addition to our Luminist Revision is the Neptune Cable line. It is the pinnacle of our Fluid shielded cables! The speaker cables are crafted around fine single crystal copper strands in a 7 AWG bundle. In order to keep the speaker cables flexible, the positive and negative signals in a channel are separated (like what’s done for the Dominus and 25th Anniversary speaker cables) making it a four (4) cable set. Neptune cables deliver a larger soundstage over the Venustas cables with stunning detail in the mid-range!

Custom for Your System

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:
  • Standard Speaker
  • Bi-Wire Speaker

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

The Neptune Speaker Cables come standard with:

  • Purist's newly designed interchangeable spade/banana.

These are our best connectors yet! They are crafted from beryllium copper with silver plating and then a final gold plating.
