This is one of the best buys in power conditioning. Internally, the Z-Center features their proprietary Z-Circuitry that cleans up and isolates the current coming in before circulating it out through its outlets. There three banks of outlets and each have their own independent filters that were designed for the specific components that will be plugged into. There two outlets for power amps (without current limit), two outlets for (isolated) for digital sources and six outlets for other analog components like preamps, tuners, etc.
Cosmetically, the unit is in nice shape. Minor scuff marks/light scratches from use but nothing major. The tiny LED light on the front needs replacing but switch on the front is clearly labelled which side is “on” and “off”. We don’t have the original box but will securely pack this for safe shipping.
