The PCA-2 is the first preamplifier from PS Audio in many years. A true state of the art design that is both a 2-channel piece as well as providing a Home Theater bypass function. You can add a phono card, USB card, or a DAC card as future otions are added to this unique product. An optional High Current Power Supply in a separate PCA-2 chassis will be available as well. The PCA-2 will have all important user functions available on the front panel as well as accessible with the included remote control.
