Now available with new black beadblast aluminum spacious barrel allowing for maximum room with even the largest of cables.
The Eidolic 2.5 mono plug is a complete solution for the Oppo PM-1 / PM-2 / HE1000 / Edition-X headphones, for a product that allows for a simplified installation process, enhanced durability, superior ergonomics, and a unique appearance.
Ideal installation conditions. The solder contacts inside the plug are thoroughly insulated and properly spaced to allow effortless cable installation. Just solder the positive and negative wires for each channel’s Eidolic 2.5mm plug, screw on the barrel, and top up the barrel with hot-melt adhesive for a cable that will last the life of your headphones. This design has been prototyped and tested over an extended period to ensure it goes the distance. The barrel is treated to ensure its interior is nonconductive, and the plug avoids the use of magnetically charged materials wherever possible.
The best metallurgy for each design. A high-conductivity, high strength combination of gold and brass is employed for this connector. Superior plating thickness and complete plating of all plug surfaces set this connector apart.
Unique barrel aesthetics. The Eidolic 2.5mm mono plug is incredibly light and compact due to the choice of materials, which also confer a near-indestructible exterior. The anodized aluminum shell is textured with a proprietary process that yields a tough, matte finish that sparkles in the light. A subtle Eidolic logo is screened and heat-cured onto the upper area of the barrel. Nothing short of a hacksaw can damage the exterior.

IACS (International Annealed Copper Standard)
The IACS rating is the metric used to describe a metals conductivity as compared to the standard of copper.
First take a look below at pure metals conductivity ratings.
(1) OCC Pure Silver - 107%
(2) OCC Copper - 103%
(3) Copper (common grade) - 100%
(4) Gold - 73%
Silver is the best there is, in pure form, period.
If you take a 1"x 1"x 1" cube of pure silver and compare its conductivity to an identical 1"x 1"x 1" cube of gold, the gold is considered 32-35% less conductive than the pure silver.
An alloy, by definition, is less pure than the original pure metals it is comprised of. Alloys are in existence largely for strength / hardness properties and are not meant for high end audio cables. When you alloy a metal, say gold with silver, you quickly decrease its purity and IACS rating. Even at just 1% gold alloyed with silver the IACS rating drops down well below plumbing grade copper. Alloys in the audio world came about purely as competition increased and there was desperation for new ways to try and market a cable to the uneducated masses.
Norne Audio will always utilize the purest form of a metal and will always use pure silver occ litz, pure copper occ litz, spc occ litz or mixes thereof. Our goal is the design that possesses the absolute top specifications of the highest possible quality.
