When output signal of some audio sources is insufficient, or the input sensitivity of the active speaker or power amplifier is too low, the entire audio system can not give full play. This preamplifier can filter out the digital sound of common audio sources and make music more soft and sweet. With op amp + tube buffer design, the music taste is more rich.
