About the REF10 Phono
The Audio Research Corporation Reference Phono 10 (often written REF Phono 10 or REF10 Phono) is a flagship, all-tube phono preamplifier for moving-magnet (MM) and moving-coil (MC) cartridges. It uses a separate power-supply chassis and provides selectable gain, cartridge loading, and playback equalization curves (RIAA, Columbia, and Decca). Its fully differential-capable output section offers both balanced XLR and single-ended RCA connections. Audio Research still lists the Reference Phono 10 in its product range, although prospective buyers should confirm regional availability and current production directly with an authorized dealer or the manufacturer.
