U-Turn Pluto Phono Preamp

Pluto is a low noise phono preamp for moving magnet (MM) cartridges. It combines high-quality components and elegant circuit design to accurately boost your turntable’s signal at this crucial stage of amplification. Pluto’s RIAA equalization network consists of WIMA film capacitors and precision resistors. It features a single high-performance gain stage and a subsonic filter to remove low-frequency noise – all housed within a steel enclosure that prevents interference. Assembled in Boston, MA.
