The driving force behind the impressive power of the Beam 3Pro is the outcome of continuous refinement and dedicated product research and development. In early 2020, Audirect Beam2 switched to the ESS 9281C, a new-generation portable DAC chip, and boosted the Mini DAC's operating current to an 11V positive and negative voltage gap using multiple LDOs (Low Dropout Voltage Linear Regulators). This laid a strong foundation for future driving power enhancements. The Beam 3Plus introduced a multi-stage amplifier structure to further amplify overall power. Consequently, with the Beam 3Pro, the original amplifier design supporting 3.5mm single-ended and 4.4mm balanced connections was merged, forming a two-stage amplifier structure akin to a desktop system.
