High-end audiophile power cable with silver-plated OCC conductors and air dielectric
A reference upgrade for high-end hi-fi and AV systems
The IsoTek EVO3 Ascension is a premium power cable designed to take mains power quality to an even higher level in high-end hi-fi and audio-video systems. IsoTek describes it as a design developed to lower background noise, improve microdynamics, openness of the soundstage, and overall precision, with highly sophisticated construction in both geometry and materials.
Silver-plated OCC conductors, cryogenic treatment and advanced insulation
The design uses three 4.0 mm² silver-plated Ohno Continuous Cast (OCC) copper conductors, deep cryogenically treated to -196°C . Each conductor is wrapped in a partial contact FEP air dielectric , then further insulated and spaced using FEP air tubes . The construction also includes a Mylar/OFC barrier , OFC braid shielding , and a highly flexible PVC outer jacket , designed to reduce interference and best preserve current purity.
Audiophile connectors and high current capacity
The EVO3 Ascension is terminated with high-grade audiophile connectors made of silver-plated OFC , designed to ensure high conductivity and contact quality. The most common standard lengths are 2 m, 3 m and 5 m , with custom lengths available depending on the market. Sources report a very high current capacity , indicated up to 55 A , and a large external diameter, around 17.5 mm , consistent with the product's top-of-the-range positioning.
