The Mofi Electronics MasterPhono Phonostage was created in collaboration with the revered audio engineer Peter Madnick, renowned for his exceptional contributions to the high-performance audio industry, this all-analog preamplifier is a testament to his expertise. The mission behind the MasterPhono was unequivocal: to replicate the sonic integrity that characterizes the renowned MFSL vinyl reissues. Over a year of meticulous research, development, and prototyping was invested to meet this lofty goal.

The MoFi Electronics MasterPhono Preamp is a high-quality, discrete phono amplifier designed by 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.

One of the most remarkable aspects of the MasterPhono is its versatility. With separate inputs and balanced as well as single-ended outputs, this preamplifier offers a multitude of user-configurable settings, all intuitively accessible via the front panel. The analog meters on the front panel embody the true essence of MasterPhono's analog heritage. Notably, a USB input opens doors to future features and software updates, ensuring a forward-looking experience.
