Phono Box RS



A reference class phono preamp with unique impedance control  

This ultra low noise and distortion preamplifier is made for the audio connoisseur. Those who seek not only breathtaking performance, but also the versatility to adapt to virtually any phono cartridge through variable impedance control. You can even adjust impedance during playback. We've used only the best components in constructing this flagship phono preamp: the SSM2019 from Analog Devices as input stages, and the Linear Technology LT1010 as the high current buffer stage, guaranteeing ultra low levels of distortion and noise.

Fully passive RIAA and DECCA equalisation is selectable. The Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. Vinyl playback has never sounded as clear, detailed and smooth, than with this superlative phono stage.
