Description

I’m selling a brand new Fosi Audio Box X2 phono preamp. I never used it. It’s a tube+solid-state hybrid phono preamplifier designed for MM (moving magnet) cartridges and provides selectable gain settings to match different turntable setups. The front has a headphone-style input/indicator and a large gain/setting knob; the top features two visible vacuum tubes for warm analog character. This unit is compact and easy to integrate between a turntable and an amplifier or powered speakers.
