Intorducing the Therium Series 2 (v2), evolved from our popular original Therium but now with various improvements.  The Therium v2 now comprises a bigger gauge, improved sound and top comfort for the gauge size. Configurable in both 4-wire (24awg) and 8-wire (22awg).  

The Therium 2 utilizes the best possible metal and design on the planet (silver occ + litz enamel stranding).  Containing the highest purity silver occ litz that is achievable from our factory along with the highest possible IACS % rating of any metal.  We have designed a new internal configuration with carefully tested and specifically arranged stranding to bring highest level transparency with maximum detail and micro-detail.  By using 100% pure cotton cores the strand bundles are kept in the desired tubular shape (arranged where the current prefers to flow), and also deadens any internal mechanical vibration of the strands without affecting flexibility.  With TPU as our outer jacket we get the ultimate in flexibility, top durability, the lowest microphonics as well as the best Triboelectrtic values (material matching enamel coating, outer jacket and triboelectric neutral cotton cores).  With this combination of materials we achieve the most neutral triboelectric values internally.  The Therium 2 reference pure silver occ litz replacement cable 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, the Therium 2 brings a neutral and uncolored window to your portable high end system.

Why OCC?

Used throughout the high end audio industry in most flagship cable products, occ provides the superior quality copper and silver possible today.OCC (Ohno Continuous Cast) is the name given to the casting process developed to help defeat annealing issues and virtually eliminate all grain boundaries in copper or silver with a unique patented process. The OCC casting method uses specialized heated moulds in order to draw a single crystal up to 125 meters in length. With only a single crystal in very long lengths, there is an unimpeded free path for the best possible signal transfer. Along with this superior single long crystal structure, OCC provides copper and silver with the least possible oxides and other impurities. 

Why Litz?

With each strand utilizing a razor thin enamel coating, Litz based wire provides a cable that will last a lifetime (will not oxidize).  Further with each strand acting independently until joining at the termination point, the design negates any bad effects typically associated with normal stranded wire (skin effect, proximity effect, etc.).  As another side benefit durability and flexibility are both increased.  

Combining OCC (purest metal) with Litz design you really have an end result that is the ultimate cable possible today.  

Why Pure OCC Copper, Silver and Silver coated Copper are the absolute best

We go by the numbers using science as the guideline.  All metals have a conductivity rating as describe by the International Annealed Copper Standard (IACS).  All metals are compared against Copper at the 100% IACS rating mark.  OCC Copper is rated at 103% IACS and Silver 106% IACS.  Gold is rated at 73% IACS or 27% lower conductivity as compared to standard OFC/ETP copper (given the exact same amount of each metal).  Therefore it would take a significant amount more Gold to achievethe higher conductivity rating of copper.  

We will never release anything less than OCC copper and will never release any alloys. So what is an alloy?  An alloy is defined as a mixture of two or more different metals, making the original metal less pure with worsened electrical performance than the original pure metal.  An alloy of 1% gold with 99% silver would yield around 89% IACS rating or 11% less conductivity than standard OFC/ETP copper.  While cables made of metals/alloys that are inferior to copper may alter the sound in a specific way, that is not our goal.  Norne Audio will always seek to utilize the absolute best materials (going by the numbers) in our pursuit of the absolute best cables possible today.  We believe that the cables with the best specifications yield the best possible sound of ones system.


Please watch the above animation if you prefer a quick visual overview.  

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.
