Created in collaboration with the revered audio engineer Peter Madnick, renowned for his exceptional contributions to the high-performance audio industry, the all-analog MasterPhono 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.

ELEVATING VINYL PLAYBACK WITH PRECISION ENGINEERING
Created in collaboration with the revered audio engineer Peter Madnick, renowned for his exceptional contributions to the high-performance audio industry, the all-analog MasterPhono 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.

VERSATILE INPUTS, INFINITE SOUNDSCAPES
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.

PRECISE INPUT FLEXIBILITY
Choose between standard signal input ("Voltage Input") via RCA & XLR or "Current input" tailored for low source-impedance phono cartridges, utilizing "Trans-impedance dynamic loading.

PERFECT LOADING
Find the perfect match for your cartridge with 10 switchable impedance loading adjustments, including a “Custom” via RCA plug on rear panel.

DUAL FUNCTION VU METERS
Dual meters can be used for monitoring or calibration of cartridge azimuth.
"Even with 45 years of experience, I'm excited to work with MoFi on a project like this —something unique, designed, and built in America — that provides high-end performance for people who love music and vinyl. I sincerely hope you get to experience MasterPhono yourself."
