Cleaner Power for Audible Improvement: Reduces ripple noise commonly introduced by switching power supplies. By delivering clean, stable energy, D2/D2 PRO helps create a darker background, better instrument separation, and smoother highs, supporting more natural and detailed music reproduction. Flexible Dual-Output Power: D2 delivers regulated 5V power via USB and DC outputs, while D2 PRO provides stable 12V through dual DC outputs. Both support parallel output to power two compatible devices simultaneously. Ideal for DACs, headphone amps, digital interfaces, streamers, and more.
