DAC requirements change dramatically with the system around them.
A phone-based listener may prioritize low power consumption and equalization, while a desktop headphone setup needs stronger amplification, flexible volume control and preamplifier functionality.
A reference system may instead place conversion architecture, power-supply design and input flexibility first. This selection therefore spans compact dongles, portable discrete designs, integrated desktop components and ambitious multi-chassis converters. The products are best considered by use case rather than as a simple performance ladder: several combine conversion with headphone amplification, while others are designed primarily for established two-channel systems. One entry, the Schiit Audio Eitr 2, is a digital-to-digital converter rather than a DAC. It earns a place as a specialist companion for listeners who already own a DAC but need to convert USB audio into coaxial, AES/EBU or optical form.
