Title

The FiiO K9 is a desktop DAC and headphone amplifier built around dual ES9068AS DAC chips with THX AAA 788+ amplification. It supports DSD512 over USB and LDAC over Bluetooth, so it works as both a wired desk anchor and a wireless endpoint.

This is a one-box centerpiece for a desktop rig: computer or streamer in, headphones out, with enough amplification headroom that most enthusiasts stop worrying about whether their cans are being driven properly. The THX AAA topology is the clean, low-distortion sort of presentation rather than a colored one, so it pairs well with headphones you already like the tuning of.

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.
