NOTE: For all 2-pin selected cables, new model Eidolic 2-pin PEEK TeCu with locking barrel is currently a free upgrade. For all Shure/MMCX selected cables new Eidolic Rhodium plated TeCu is also a free upgrade to add.
Truly the ultimate in purity utilizing best possible metal on the planet, the Therium Reference Series contains the highest purity silver occ litz. Exhibiting our new specialized "variance" stranding configuration (a first ever for occ litz, 2015), the Therium reference replacement cable also uses a tubular design with a 100% cotton core. Our cotton core not only keeps the strands in the desired tube shape (where the current prefers to flow), but also deadens any internal mechanical vibration of the strands without affecting flexibility. One of the only cables out there using the absolute top pure cotton possible for cores, we achieve the most neutral triboelectric value possible internally. The Therium reference pure silver occ litz replacement cable truly enables any iem / ciem to perform to its maximum potential while also having the side benefit of being extremely comfortable / flexible (in 4-wire or 8-wire configuration). Boasting end-game detail, focus and precision without sibilance or fatigue, the Therium premium occ litz pure silver cable is certainly an unstoppable force and the best ciem / replacement cable possible today.
Shipping by default with the highest end and best quality ciem / iem plugs one earth (Eidolic).
The latest of which is a 2-pin plug (model Eidolic E2-78CU) that utilizes pins made entirely of Tellurium Copper for a 93% IACS rating over the typical brass in all other plugs. Select the checkbox if you prefer TeCu versus the standard Eidolic 2-pin plug. These plugs work for nearly all 2-pin type iems (0.78mm), with very few exceptions.
Shown below are the new Norne signature design aluminum micro splitters. Completely custom made from the
ground up starting with our exacting dimensions for portable cable use. We utilize one the of the best machining
companies to produce our splitters to our exact specifications. We only want the best to be part of our cables and in our view the production
method that goes into our splitters is superior to any other method of producing a metal based splitter.
Ultimate fine sandblast finishing, cnc engraved logo, special permanent color fill options, this is something that can only
truly be done with the best equipment and processes. The perfect finishing touch to a fully custom high end pure silver occ litz replacement ciem / iem cable.
Makassar Ebony & Caribbean Rosewood mini splitter available, as well as our mini triangle splitter in premium precious metal options.

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.
