The analog stage of the NADAC L is powered by a high-performance linear transformer power supply. In practice, less than 10% of its rated capacity is used, guaranteeing ample headroom for stable dynamics and ultra-low noise. For the control stage, a high efficiency switching power supply is employed. Digital circuits demand higher current, and transformer power would raise internal temperature, conflicting with the low-heat design. By isolating the switching supply and preventing interference, NADAC L ensures that the full analog audio path remains pristine, while digital control remains efficient and thermally stable.
