    Description

    The Fosi Audio P3 is a compact yet powerful tube preamplifier designed for audiophiles seeking warm, natural sound with modern convenience. At its core, it features a true vacuum tube amplification circuit powered by a 54V supply, allowing the tubes to deliver rich harmonics, smooth highs, detailed midrange, and deep bass.

    Key Features:
    1.Classic Vacuum Tube Design:The heart of the P3 is its 6K4/6J1vacuum tubes, which are clearlyvisible on the top panel. These tubesare responsible for the classic "tubesound," characterized by a smooth,musical midrange and a softening ofdigital harshness.
    The tubes are user-replaceable
    allowing for "tube rolling"_thepractice of swapping different brandsor types of compatible tubes to finetune the sound sianature to personapreference.
    2.Dual input Selection:
    lIt features two stereo RCA inputchannels,allowing you to connectand switch between two differentaudio sources,such as a DAC and aphono stage (for a turntable with anexternal preamp).
