Note that stock barrel is gunmetal anodized AL with three engraved rings ($12.85 priced per unit). When you select the Titanium Modular barrel upgrade you will receive both the stock barrel and the titanium barrel of your configuration.
Perfect size and shape. The 3.5mm connector must be small enough to fit all electronics, while large enough to accommodate substantial headphone and interconnect cables. We have a streamlined 10mm barrel diameter that will fit very compact jack layouts, but a 6.5mm rear opening will fit the vast majority of cables. The extended, narrow 3.5mm long collar behind the plug shaft allows it to fit into recessed openings such as cellphone and music player cases. The interior of the generation 3 connector is even roomier than before.
Ideal installation conditions. The solder contacts inside the plug are thoroughly insulated and properly spaced to allow effortless cable installation, without the risk of shorts or compromised insulation. In this way, we avoid tiny, stacked contacts that are easy to short and difficult to maneuver around. This design has been prototyped and tested over an extended period to ensure it goes the distance. The barrel offers ample room inside and 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-performance base metal with superior strength is employed for this connector. We offer gold and rhodium-plated variants for a complete range of choices. Nickel offers superior hardness while gold is most conductive; rhodium is the best of both worlds at an additional cost. Superior plating thickness and complete plating of all plug surfaces set this connector apart.
Upgrade to the new titanium barrel. A one-of-a-kind titanium alloy upgrade barrel with laser logo and choice of decorative insert is now possible in 2018. For more information, click here. Check the box above to opt for a truly unique connector style. Barrel is adjustable by the end-user and the length can be 20mm, 24mm or 29mm depending on ring choices. Configure your Titanium barrel to be short as possible, add a 5mm ring for medium length, or finally add a carbon fiber ring (10mm) to have the longest length. See below for images.

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.
