The SMSL PO100 is a small USB-C digital interface: it plugs into a phone or laptop's USB-C port and outputs optical and coaxial S/PDIF at 44.1-192kHz, with DSD64 and MQA support. It's the fix when a DAC, AV receiver or desktop amp takes optical or coaxial but your phone or laptop only has USB.

Who the SMSL PO100 is for

  • DACs with optical or coaxial inputs: It bridges a phone or laptop that only has USB to a DAC's optical or coaxial input.
  • AV receivers and desktop amps: Feed a legacy DAC, an AV receiver or a desktop amp a clean digital signal from a modern source.
  • Bypassing a computer's USB: Hand the DAC a coaxial feed instead of relying on the computer's own USB implementation.
  • Hotel and office setups: It's small enough to keep in a bag for listening away from home.
  • Skip it if: you want to plug headphones into it; its outputs are optical and coaxial digital, so a DAC or receiver has to come after it.
