Conductor materials
OCC copper, OFC copper, monocrystal silver, silver-plated copper, litz construction and more.
Cardas Golden Ratio Stranding (Phi-Geometry Strand Counts)
Strand-count geometry developed by George Cardas where the conductor strand counts at each layer of the bundle follow the Golden Ratio (φ…
Solid-Core Pure Copper (No-Strand Construction)
Single-conductor solid-core copper wire — typically 18–22 AWG — used in audiophile interconnects and speaker cables that prioritize cross…
Palladium-Plated Contacts (Hi-End Connectors)
Palladium-plated connector contact surfaces — the alternative to gold for users skeptical of gold's softness and prone-to-galling behavio…
PTFE (Teflon) Dielectric Insulation
Polytetrafluoroethylene cable insulation — the audiophile dielectric standard. Dielectric constant of 2.1 (vs ~3.5 for typical PVC), low…
Cryogenically Treated Copper (Deep Cryo OFC)
OFC copper subjected to deep cryogenic treatment (slow descent to -195°C in liquid nitrogen, soak, slow ramp back to room temperature). T…
Palladium-Plated Contact
Palladium plating over nickel underplate, used on connector contact surfaces in industrial / instrumentation applications. Higher mating-…
MIL-Spec PTFE Insulation
PTFE (polytetrafluoroethylene, Teflon) jacket per MIL-W-16878. Lowest dielectric constant of the practical wire insulators (2.1 vs PVC’s…
Litz Construction (Individually-Insulated Strand Bundle)
Cable construction technique, not a material: each individual strand inside a multi-strand bundle is independently insulated, and the str…
Gold-Plated Copper (Contact Surface, Not Conductor)
Gold plating on a copper or brass connector contact surface (typically 1–3 μm thickness). Not used as a bulk conductor — gold's IACS is o…
Silver-Plated Copper (SPC) — Skin-Effect Optimized
Hybrid conductor: an OFC copper core electroplated with a thin (typically 2–5% by mass) layer of pure silver. The skin-effect concentrati…
