Product Text

The DS3 B Phono Box is an example of extraordinary sound quality, designed for the true audio enthusiast. With its robust steel chassis, surrounded by aluminum, this unit offers excellent rigidity and outstanding isolation from interference. The DS3 Box adds aesthetic appeal to its functional expertise. The "B" in Phono Box DS3 B stands for 'balanced', indicating its true fully balanced amplification. Connect your turntable either with a 5-pin mini XLR cable or standard XLR cables and enjoy the benefits of the balanced signal path. With its symmetrical transmission and two separate amplifier sections, it offers a clean, dynamic, and lifelike sound experience that surpasses what integrated circuits typically can deliver. The unit also emphasizes the importance of discrete circuits, which are built from individual components that collectively offer a more detailed and vivid sound reproduction.
