The mission is the same: 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.\u003c\/span\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003ch4\u003eMoFi Electronics UltraPhono Pro Phono Preamplifier\u003c\/h4\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eSetup is fast and repeatable with gain and loading controls right on the front panel.
