MoFi Electronics UltraPhono Pro MM / MC Phonostage

MoFi Electronics UltraPhono Pro MM / MC Phonostage With single RCA input and RCA or XLR outputs, front-panel controls, and MoFi's legendary search for musical truth The MoFi UltraPhono Pro was created in collaboration with renowned audio engineer Peter Madnick. It is a distillation of the core architecture of the flagship MasterPhono, resulting in a streamlined, single-input, all-analog phonostage. The mission is all MoFi: to preserve the sonic integrity MoFi’s mastering engineers capture in the studio by extracting maximum information from your cartridge with as little loss as possible—delivering a natural, unforced presentation without unnecessary complexity. 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 tools—mono, subsonic, mute, and dim—to tailor playback for real records in real rooms, without breaking the flow of a listening session. The UltraPhono Pro is built around a fully discrete J-FET and MOSFET gain stage and a passive, zero-feedback RIAA network—choices 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. A passive RIAA equalization network with zero feedback preserves natural transients and tonal realism. Precision film-foil parts maintain equalization accuracy within ±0.05 dB. Gain and loading are right on the front panel for fast, repeatable setup. Dial in a cartridge in seconds, then lock it in with confidence.
