MoFi Electronics MasterPhono MM/MC Phono Stage

A fully discrete phonostage with balanced input and output, switchable gain, and 10-position loading adjustment. 

The MoFi Electronics MasterPhono is a high-quality, discrete phono amplifier designed by renowned sound engineer Peter Madnick for unmatched flexibility and silent operation.

Featuring fully balanced input/output, a shielded internal power supply, and programmable resistance and gain, MasterPhono delivers an accessible, high-performance experience without artificial coloration, staying true to the original master tape sound.
