High Precision, Low Complexity

Phono Box MM is a high-precision European-built phono preamp specifically for use with moving magnet cartridges. It uses low-noise circuitry and accurate RIAA equalization for a seamless, non-fatiguing playback that’s more convincing than its price suggests. The low-impedance output stage allows for longer cable runs with minimal distortion, and gold-plated RCA ins & outs are used to preserve signal integrity.
