The PO100 PRO is a compact XMOS XU316 digital interface that turns USB-C into I2S (LVDS), optical and coaxial output — up to 32-bit/768kHz PCM over I2S, with native DSD support and MQA handled without extra software.

Note there is no analog output: this is a digital bridge. Two clear use cases — feeding an older DAC that has great analog stages but a dated USB receiver, or pulling a cleaner S/PDIF feed out of a noisy computer. If your DAC has an I2S input, that's where this pays off most.

  • XMOS XU316, USB-C input
  • Outputs: I2S (LVDS), optical, coaxial
  • PCM up to 32-bit/768kHz over I2S, native DSD, MQA
  • Digital only — no analog output

Frequently asked questions

Is this unit genuine?

Yes. TonePier is an authorized retailer — every unit comes from the brand or its official distributor, carries a valid serial number and is covered by the full manufacturer warranty.

How long does shipping take?

SKUs stocked in our US warehouse ship within 1–2 business days. Items shipped direct from our China hub typically arrive in 8–15 days with full tracking. The product page tells you which applies before you order.

What if it isn't for me?

You get 45 days to decide. Keep the packaging, keep it in like-new condition, and send it back for a refund. Ear tips unsealed for hygiene reasons are fine — we expect you to actually listen.
