The SMSL D6s is an MQA desktop DAC built on the ES9039Q2M chip with an XMOS XU316 USB interface, offering full MQA decoding including MQA-CD, Bluetooth 5.1, a remote, and XLR and RCA outputs in a 0.59 kg chassis. It suits systems that already have a headphone amp or active monitors.
Who the SMSL D6s is for
Systems that already have amplification: Run it into a headphone amp or active monitors from its XLR or RCA outputs.
MQA-CD owners: Feed it from a CD transport and it unfolds MQA-encoded discs properly.
Casual phone listening: Bluetooth 5.1 handles the casual listening that a USB cable makes awkward.
Multi-source desks: USB, optical, coaxial and Bluetooth inputs let several sources share one DAC, and a remote is included.
Skip it if: you need a built-in headphone amp; the D6s is a DAC meant to feed an amp or active monitors through XLR or RCA.

SMSL D6s vs similar options
vs FiiO BTA30 Pro: The BTA30 Pro is a Bluetooth transceiver that can also transmit LDAC to wireless headphones, with an RCA line out; pick the D6s if you want XLR as well as RCA outputs.
vs SMSL DO100 Pro: Doubles up to dual ES9039Q2M chips and adds an HDMI-ARC input for a TV or console; the D6s is enough if your sources are USB, optical, coaxial or Bluetooth.
