The “O” part of the upgrade designates the use of OHNO oxygen-free continuous cast copper (OCC), 6 nines purity mono-crystal wiring throughout. This is Audience’s top of the line AC power wire design specifically applied for the internal wiring of Audience power conditioners. It yields improved resolution, greater musical “speed” and immediacy and better sound-staging.
The “X” designation indicates the use of new rhodium plated copper internal contacts in the AC outlets. The copper contacts provide the very highest conductivity and the quality rhodium plating prevents oxidation of the copper. These high conductivity receptacles improve virtually every aspect of a system’s audio reproduction.
Further, all new Audience power conditioners now have gold plated copper forks to connect the power conditioners’ filter capacitors to the AC duplex outlets. This construction replaces the previous tin plating-over-copper forks. The new forks provide a noticeably more refined musical presentation.
