The Aune S17 Pro is a fully balanced desktop headphone amplifier using a Twin JFET R2R Class A design. It's a proper end-game-adjacent amp: the kind of box you buy once you already know which headphones you're keeping and want to hear what they actually do.

Class A runs warm by nature, so give it air on the shelf. Pair it with demanding planars or high-impedance dynamics via balanced cable, and feed it from a dedicated DAC — the S17 Pro is an amplifier, so it's the second half of a stack rather than an all-in-one. If you've outgrown a combo unit, this is the natural upgrade path.

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.
