Au24 SX audio cables represent the biggest transformation in cable performance ever achieved by Audience. ALL of the SX cables are notably more transparent, dynamic, more resolved and have greater weight and authority, immediately noticeable. Everyone who has tried them thus far has been very impressed with the advancements we have achieved through the use of purer OCC copper (now six nines) and higher quality XLPE dielectric insulation as well as tweaking of geometry as compared to the historic lines of Au24 cables. Audience double cryogenically treats all SX cables in our in-house cryo lab. Each component part of the cable is individually treated, then, after the cables are assembled and tested, we cryo the completed cable. This is process is called CRYO².
