Prelude Cryo Speaker Cable (Bulk)

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.

What is going on with CRYO Treatment and Audio Cables?
Despite all the wild claims, DH Labs believes the only truthful answer is that no one really knows for sure. The exact mechanics of the process are proven by metallurgists to increase the strength and durability of metals. With cables, it is speculated that the crystal boundaries of the conductor are being changed/improved and that the dielectric material also experiences a positive improvement.

Physical/mechanical properties of the metal appear to be altered which is why an instrument like a French Horn will have superior resonant qualities after cryogenic treatment. From a subjective standpoint, common evaluations of cryo-treated vs non cryo-treated cables are:

• Wider Dynamic Range

• Smoother, More Refined Highs

• Better Bass Articulation/Extension

• A More Organic Presentation

• Deeper & More Dimensional Soundstage

DH Labs has developed their Deep-Cryogenic processing specifically for audio cables and connectors. This consists of a computer-controlled, slow cool-down cycle down to the temperature of nitrogen at -320 Degrees F. By introducing these lower temperature by means of a heat-exchanger, they are able to prevent the materials from being “cold-shocked” by direct contact with liquid nitrogen. Once the materials reach -320 degrees, they are “cold-soaked” for an extended period before being slowly ramped back up to ambient room temperature. The best part is that once treated, the cryogenic effect becomes permanent!
