Prelude uses 11 AWG cryo-treated OFHC copper to deliver rich, natural timbres while improving depth and low-level detail.

DH Labs has always understood that the way a cable is handled and extruded during the manufacturing process is paramount to cable performance. Advanced metallurgy is critical when producing OFHCC long-grain Continuous Crystal™ Copper, which is superior to OHNO in that it has the longest grain structure of any copper variation. Longer grains help deliver more natural timbres and dynamics. Our 11 AWG PRELUDE uses this material, paired with a low-loss polyethylene dielectric and delivers a warm and rich presentation, with deep well-defined bass.

Cryogenic treatment does not magically transform the performance of cables, but in the case of Prelude, it does provide a noticeable improvement in soundstage depth and low-level detail that helps to extract maximum performance.

Our proprietary copper technology (available only in the USA) features higher purity and lower electrical resistance than OFHC, OFC, and OHNO Copper offerings, sonically outperforming competing manufacturers.
