Audience Power Conditioners: What do all of the letters mean?
The “O” part of the designation means 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.
The "T" designation indicates the use of Audience's Teflon Auricap. The Teflons have more high frequency extension. This is a major sonic difference. The Teflon caps are less forgiving, and more revealing than the standard Auricaps. It's a tradeoff of smoothness and forgiveness for resolution, air, space, and detail.
The "S" designation represents the ground plane technology Audience incorporates. This reduces noise significantly, and can be described as revealing low level detail, and the space between the notes becomes blacker.
