Title

The xDuoo MH-02 pairs a CS43131 DAC with a 6J1 tube headphone amplifier stage, decoding DSD256 and 32-bit PCM over USB. It is a compact way to get an actual tube in the signal path on a desk.

Choose it if you want a bit of tube character on top of a clean digital front end without committing desk space to a full-size amp. The 6J1 is a widely available tube type, so rolling in a different one later is a straightforward experiment.

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.
