Mobile Fidelity – UltraPhono Pro

Description

ULTRAPHONO PRO

Created in collaboration with renowned audio engineer Peter Madnick, UltraPhono Pro distills the core architecture of our flagship MasterPhono into a streamlined, single-input, all-analog phono stage. The mission is the same: preserve the sonic integrity MoFis mastering engineers capture in the studio by extracting maximum information from your cartridge with as little loss as possibledelivering a natural, unforced presentation without unnecessary complexity.

DIAL IN YOUR CARTRIDGE, STAY IN THE MUSIC

Setup is fast and repeatable with gain and loading controls right on the front panel. Choose the setting that fits your cartridge, then use practical listening toolsmono, subsonic, mute, and dimto tailor playback for real records in real rooms, without breaking the flow of a listening session.

ENGINEERED FOR LOW-NOISE TRUTH

UltraPhono Pro is built around a fully discrete J-FET and MOSFET gain stage and a passive, zero-feedback RIAA networkchoices made to preserve natural transients and tonal realism without editorializing the source. A seven-stage regulated power supply provides an exceptionally quiet foundation, letting dynamics and low-level detail come through with ease
