Advancing in a positive, notable way is always a tightrope act for any cable manufacturer. Yet, gradually and concisely, Knut Skogrand has managed to elevate both his brand and his cable products over the years.
A few years ago, Skogrand made a major shift with his brilliantly executed rebranding—infused with Nordic mythology and proprietary manufacturing techniques, materials, and approaches—a secret he promised to unveil at his retirement in a grand gesture (a rare, exclusive, and properly aged Highland spirit inclusive) somewhere in the Norwegian highlands.
The Skogrand Way
Skogrand cables are crafted in a boutique workshop nested in Norway’s mountainous highlands.
Knut Skogrand’s work is rooted in a millennium-old legacy of deliberate, purposeful craftsmanship, aligned with Norway’s heritage of master artisans who pour pride into perfecting every detail when designing and engineering these handmade, artisanal products.
This ethos of meticulous attention to detail and exacting standards echoes throughout Norway’s cultural and technological achievements—from the intricate timberwork of soaring stave churches and the ingenious Viking longships built for both speed and resilience, to pioneering advancements in hydroelectric systems and petroleum innovations that lead global industries.
Air Dielectrics
The most common cable insulator material, PVC, has a dielectric constant of 3.5 to 4. A higher dielectric constant means the material stores more electrical charge, making it less suitable as a cable insulator and negatively affecting the ability to preserve and deliver the electrical signal.
The velocity of propagation is directly linked to the dielectric properties of the insulator. In ideal conditions, a signal travels at the speed of light through a vacuum. The dielectric constant describes how well an insulator stores electrical charge (as seen in materials used for capacitors) or, conversely, how freely it allows electrons to move (with low or ultra-low dielectric constants, the vacuum being the ideal).
When the insulator in a cable has a lower dielectric constant, it stores less charge, resulting in minimal losses along the signal path and ensuring that the signal is preserved more completely from end to end.
Additionally, a lower dielectric constant allows electrons to move and interact more freely, enhancing signal transfer. The closer the insulator’s dielectric constant is to that of a vacuum, the less charge it stores, preserving more of the signal and enabling the fastest possible transfer in a cable where wires are suspended in the air.
Skogrand takes pride in stating that their air dielectric frameworks yield the most efficient electrical conduits on the global market. With an air dielectric efficiency above 99.28%, Skogrand cables offer exceptional signal preservation and facilitate rapid, unambiguous signal transfer. This near-ideal performance closely approaches the theoretical perfection of a vacuum.
In summary, by minimizing the dielectric constant, Skogrand cables reduce unwanted charge storage, maintain signal integrity, and achieve high-speed electron transfer. This results in a pristine transmission environment where every nuance of the electrical signal is preserved, setting a new benchmark in cable performance.
Silverspine
The Skogrand Cables Silverspine is the brand’s inaugural cable model, featuring a more conductive wire than single-grain solid-core copper.
Instead, it employs single-grain solid-core silver wires that float suspended in the air throughout the entire cable length—from termination to termination—utilizing our proprietary air-dielectric framework constructs.
Drawing upon the Skogrand Stravinsky model, it incorporates modifications to cater to the unique properties and characteristics of the silver wire, ensuring its pristine condition over time.
The Music
With Skogrand Cables’ Silverspine, music is simply waiting to be discovered, and Silverspine recalls a mix of fondness and vivid memories from my previous experiences with various Skogrand cables.
As always, here are a few references pointing out the Silverspine XCR cables’ stand-out attributes.
Danzas españolas: Oriental
“Classica Española” combines a diverse repertoire of Spanish musical heritage, drawing on the works of renowned composers such as Albéniz, Granados, and Falla, alongside modern interpretations such as Chick Corea’s “Spain.”
From the outset, Skogrand Silverspine masterfully weaves fundamental music interlinks that showcase its unique ability to delve straight into the playful interplay of classical Spanish instruments. This is further elevated by a factual rendition of the traditional sonic palette—including classical and flamenco guitars, double bass, and the striking real-world authenticity of castanets and cajón.
