Clearaudio Balanced Reference Phonostage

We designed our Balanced Reference Phonostage to establish a true reference status. It has taken years of tireless research and passion to realize the full potential of this component.

The Balanced Reference Phono Stage features top quality parts and construction throughout, including separate massive cases, fully symmetrical circuits in both the preamp and power supplies, and stepped attenuated regulation.
