This ultra-low noise and distortion preamplifier is made for the audio connoisseurs and offers not only breathtaking performance but is capable to adapt to virtually any phono cartridge through variable impedance control. Impedance adjustment can be done while playback! Due to the use of best parts, like SSM2019 from Analog Devices as input stages and Linear Technology LT1010 as high current buffer stage, Phono Box RS delivers ultra-low levels of distortion and noise. It’s very low output impedance makes it insensitive to the selection of interconnect cables and lengths.
Fully passive RIAA and DECCA equalisation are selectable. Phono Box RS offers fully balanced circuitry and both XLR and RCA inputs and outputs. All in all vinyl playback will never have sounded as clear, detailed, and smooth, then with this superlative phono stage!
