Corona Cryo AC Power Cord

Corona CRYO delivers magnificent transient response with a very low noise floor. Construction starts with Oxygen Free Continuous Crystal Copper (OFHCC Long Grain) developed specifically for audio applications. Each conductor is insulated with PTFE dielectric material which was chosen to isolate vibration caused by alternating current from entering the signal path. A proprietary stranding overlay/twist is employed for maximum noise rejection and the cancelation of magnetic fields to eliminate distortion. Corona CRYO is triple shielded, offering enhanced protection from RF and EMI noise and audible improvements from a lower noise floor. Finally, the cable is meticulously hand assembled using a custom manufactured DH Labs connector with Rhodium Plated Tellurium Copper and an anti-resonant carbon fiber / aluminum shell.

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!
