This is not just a DAC; it's a gateway to a more intimate and emotionally resonant musical experience. The presence of tubes in the output stage is a key differentiator, and it's what sets the Aero DAC apart from its solid-state counterparts. This component provides the signature warmth and spaciousness associated with tube amplification.
