Eidolic Peerless 4-pin XLR

Peerless Eidolic connectors are cost-no-object designs with parts carefully considered and crafted to the highest specifications.  All functional components are chosen for peak performance, and all aesthetic components are made with exotic materials and styles unique to Eidolic.  The satin titanium shell is machined from a 1-inch solid rod and polished with diamond media, which stands in gleaming contrast to the modular inlay at its center: an intricate composition of grooves and columns machined into a tube of aircraft aluminum alloy.  The inlay’s charcoal-toned alloy plating is set off by the burnished gray of the 6AL-4V titanium alloy surrounding it.  The shell protects 4 lustrous pins inside a white bulkhead— and there is much more than meets the eye…

Peerless exterior.  A solid 6AL-4V titanium alloy shell secures the high-grade components within.  A tough and functional connector can still be fine art, thanks to the chamfered edges and circular-polished finish.  The back cap of the XLR connector features engraved rings for a secure grip and includes a silicone grommet to seal the connector.  Traditional CNC machining is not adequate for this connector.  The internal grooves must be wire discharge machined–slowly eroded by an ultra high voltage plasma electrode a few microns at a time. This laborious process means that it takes almost a day’s work to complete just one part.

Peerless customization.  In keeping with Eidolic’s 2018 titanium revolution, the modular design allows for a choice of central insert, which slides into place during assembly and is retained by the titanium back cap.  We anticipate an array of insert materials going forward.  Currently, the Peerless 4-pin XLR includes a finely-engraved aluminum insert (available at launch, choice of dark alloy-plated or high polish silver aluminum finish) or carbon fiber with blue metallic woven filaments (late 2018).  

Peerless insulation.  Most XLR connectors use varying grades of plastic (glass-filled PBT or Delrin) or even entry-level Teflon formulations (PVDF) but the gold standard for polymers is, and will continue to be, PTFE Teflon.  It is the most stable material for CNC machining but also offers the strongest heat resistance for soldering and the most effective dielectric constant for high electrical performance.  It is because of these qualities that we selected PTFE Teflon for our connectors—it will not have any impact on signal quality, nor will it scorch, melt, or otherwise corrode with time.  Terminating a cable with these connectors is a worry-free process as even liberal applications of heat will not damage the pin-insulator interface.  Despite being a boutique connector, it is equipped with industry-standard chuck type strain relief for cable retention, so glue is not typically necessary.  

Peerless contact pin material.  The humble stage-grade XLRs use brass pins, while plenty of high-end XLRs use bronze pins and the Eidolic E-T4PR connector uses tellurium copper pins.  These offer ascending conductivity and performance, with a very select few of the industry’s most expensive connectors using pure copper pin material (~100% IACS conductivity).  The Eidolic Peerless 4-pin XLR is the first production 4-pin XLR to use 99.9% pure fine silver for its pin material – an extravagant metal stock that is painfully slow to machine owing to its relative softness.  This material, at over 106% IACS conductivity, puts this connector at the absolute limit of electrical performance.  When used with the world’s best headphone cables, the perfect signal path is further extended.  

Peerless plating.  We chose rhodium plating for this model due to its combination of conductivity and stability.  A bare, unplated silver pin or silver-plated copper pin is fine at the outset, but requires continuous maintenance as its surface breaks down and develops unsightly pitting.  Gold plating is both stable and conductive but is relatively soft and therefore not ideal for regular use. The superior hardness and thinness of rhodium plating makes for a stable amp-cable interface with low resistance and low impact on the signal.  

Peerless endurance.  All the components of this heirloom-grade connector can be cleaned, polished, reused, exchanged, or replaced.  A quick polish with 1500-grit sandpaper keeps the shell looking its best.  The PTFE insulator and rhodium-encased silver pins are at the height of environmental resistance and wear tolerance.   This is connector you will want to reuse – its modular design means it could someday be a 3 pin XLR, bear a different decorative insert, or be used in subsequent cable projects.

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.
