Audio Research Reference Phono 10
The Reference 10, providing an unsurpassed level of performance in its category. The front panel has a 7” diagonal touch screen mounted asymmetrically, and only two buttons for power and mute. The interactive touch screen allows the user to change inputs (and input names), equalization, loading, gain, muting, foreground and background colors of the display, display intensity, and tube hours.
