Zesto Audio - Andros Spirit MM Phonostage

Zesto Audio Andros Spirit MM - Pure Tube Performance for MM Cartridges

The Andros Spirit MM is designed for analog lovers who use Moving Magnet (MM) or High-Output MC cartridges and seek Zesto Audio’s premier tube quality at a more accessible price point. By omitting the Step-Up transformers

required for Low-Output MCs, Zesto delivers a pure-bred, all-tube phonostage that focuses entirely on the high-fidelity amplification of the MM signal.Despite its lower price tag, the Spirit MM retains the 100% Pure Class A tube circuit

that made the Andros series famous. With two selected 12AX7 tubes and a design featuring no transistors in the signal path, it offers a full-bodied sound with natural textures and "air" that dramatically upgrades any turntable. The ability

to choose between two input impedances (47K and 15K Ohms) allows for precise matching with your cartridge, ensuring optimal frequency response.
