SMSL DO100 Pro: a Hi-Res desktop DAC with dual ES9039Q2M converters, OPA1612 op-amps and DSD512 support, plus HDMI-ARC and Bluetooth 5.1. It's aimed at desks that juggle music, console gaming and TV or film and want one shared stereo DAC feeding a headphone amp.
Who the SMSL DO100 Pro is for
Console and TV audio: The HDMI-ARC input brings a console or TV into the chain, not just a computer.
Shared music, gaming and film desks: Run it as the one DAC for all three and you collapse three sources into a single volume-controlled hub.
Headphone amp owners: Feed a headphone amp from its outputs and let the DO100 Pro handle conversion.
Mid-tier desktop chains: It anchors the chain as a proper stereo DAC rather than a headphone-only box.
Skip it if: you want one box to plug headphones into; the DO100 Pro is a stereo DAC, and the suggested headphone setup runs a separate amp from its outputs.
