Why PTL (Pure Textile Layered)?
PTL is the design type that we truly feel is the end of the road in headphone cables based on our nearly 14 years experience. Being the first ever in the industry to combine OCC (Ohno Continous Cast) and Litz (enamel coated strands) in headphone cables back in 2011, we have developed countless design iterations over these many years to try and maximize results with this combination. PTL (Pure Textile Layered) is the final end result of this time and effort. Combining PTL with silver occ litz, copper occ litz or a combination of the two you get truly an unsurpassable cable in our view. Silver occ litz or Copper occ litz are in fact the best metals you can use for a headphone cable, and there is no better metal from a science based view. Palladium, gold alloys and everything else is merely marketing bait trying to hook those that are unaware of materials and their respective IACS ratings / science based properties. We are proud to offer the best metals with the best design type in a variety of our series (copper, silver or fusion). Our PTL design type is now available on the Skollvar v3 as well as the largest gauge (up to 15awg range) Silvergarde SC5 fusion (in stock). We also now have preorder discounts open for the Silvergarde S5 100% silver occ litz PTL (arriving soon). Just email us at: NorneAudioCables@gmail.com for inquiies. - last updated 09/17, estimated arrival of Silvergarde S5 in stock by October 1st.
(new) Skollvar v3 PTL (Pure Textile Layered)
The Skollvar v3 now utilizes our unique and peerless Pure Textile Layered (PTL) Design, delivering what we feel are the best internal materials achievable for a headphone cable. The primary layer of our PTL design uses 100% pure cotton, followed by a secondary layer of very flexible teflon wrap. Internally (within our strand bundles) we utilize carefully structured and sized 100% pure cotton cores. Pure cotton is the best possible material when in contact with litz strands, being the most neutral in triboelectric series. We strongly feel that the biggest gauges will all benefit from a PTL (best materials) design not only in sound but also with a fantastic side benefit of top physical comfort. The design is a best of all worlds type. There is of course no better metal than silver occ litz and copper occ litz for headphone cables, and we feel there is no better design type than PTL (Pure Textile Layered).

For an added fee you can work with us to create something fully unique for your Skollvar v3 PTL 8-wire square braid in any combination of color choices (various patterns). Our sleeving is custom manufactured for us by a 60+ year old company in the USA, responsible for supplying some of the most premium brands in the fashion industry and elsewhere. We have yet to find a sleeve that can surpass the quality that this 60+ year old textile company produces.
Please stay tuned for more images to be added.
Image below: Sleeve #1 - Black + Sleeve #2 - Dark grey & Silver herring bone (single alternating braid pattern)
19awg per polarity with a total of 8-wires internally
OCC (Ohno Continous Cast), the best metal type
Litz (enameled strands, each strand insulated with a razor thin enamel until termination point, negating skin effect / oxidzing.)
Fusion design with a larger 50% per polarity as true pure silver occ litz + the other 50% as copper occ litz.
New peerless PTL Design type (Pure Textile Layered) - the ultimate headphone cable design type possible in our view
Ultimate primary layer material of 100% pure cotton (most neutral in Triboelectric series) + thin teflon secondary wrap layer
Specialized strand processing and the best strand bundle twist / pitch control for the most optimal results
Utilizing carefully sized and structured 100% cotton cores in each conductor
Benefiting from the best current factory on the planet for our OCC metal (head to head testing compared to all other OCC metal producing factories, ours ranked highest in our tests)
Each individual wire has carefully selected strand counts and composition to achieve our end-game goals.
Each PTL fusion silver occ litz+copper occ litz conductor is sleeved by hand and formed into our 8 wire square braid, requiring more hand labor than most designs on the market. (noting that clear polymer jacket cables are the easiest to produce by far in 4/8wire, very simple)
A resulting lighter and more ergonomic cable than other headphone cables design types, even in the largest gauge sizes (we eliminate the thick polymer jackets).

If you want something truly custom please just email us via our contact page. We can do various logo fill color options in our raised silver inlay and raised black inlay splitters.
Combine any base color splitter with any inlay option.
See our sleeve list below for other combinations possible on this series. If not in the drop down, you may combine any two of the below sleeves by putting them in the checkout notes.
Shown above are various sleeve options available for the Skollvar v2.
If there is a particular amplifier or headphone end termination you do not see, odds are we can make it. Please just email us via contact form to confirm what you are after
and we will work out the details with you. For example Furutech 4-pin XLR or 1/4" TRS rhodium, etc.
Exotic Wood custom splitters:
Please note that all exotic wood splitters are hand crafted on a per order basis. These custom wood splitters take a lot of labor and will delay an order longer than a metal splitter.
If you are after the quickest shipping cables select the metal splitter option. Stay tuned in the near future for our wood with metal flush inlay options (coming soon, a perfect match to many wood+metal grill headphone cups)
Exclusive splitter inlays:
Our custom splitter inlays are precisely formed via CNC process and merged with any desired deep recess triangle splitter currently available (see images above). Stay tuned for more options to be added during Black Friday 2022 and beyond.
We are proud to say that our outer textile sleeves are 100% made in the USA to the highest quality and standard. Our sleeves are not simply something you can find off the shelf and they have their own extremly nice quality and feel. The factory we are using in the USA only adheres to the highest standard of quality given their long list of other prestigious clientelle. Not only possessing a top feel, our sleeves are very durable with a lower level of mechanical noise (microphonics). Our special metallic fiber tracer sleeving is original to us in headphone cables, having spent years working to locate what we feel is the best sleeve out there. We are also the original source of this special sleeve with metallic fiber look for headphone cables.
Every Skollvar v2 Series headphone cable ships with our custom Black top metal zipper bag.
Please note: Page description under construction, check back soon for more details. See bottom for specs.
Please note: All cables are hand made on a per order basis and have a wait time, we cannot rush shipments on request currently. We have a vast amount of customization options meaning they must
all be built by hand from scratch on a per order basis (not premade). If you need to know a wait time, please contact us with your specifications for an ETA on your specific build before ordering.

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.
