The AO300 PRO is an all-in-one desktop hub that replaces a stack. A CS43131 DAC with XMOS XU-316 covers 32-bit/768kHz PCM, DSD256 and MQA, while MA5332MS Class D power delivers 165W x2 into 4 ohms for passive speakers. Both 4.4mm balanced and 6.35mm headphone outputs are on the front.

HDMI eARC with CEC, Bluetooth 5.3 with LDAC and a filtered subwoofer output make it a real living-room or desktop centerpiece: TV, computer and phone in, speakers plus headphones out, one remote. Good choice if you're consolidating a cluttered desk rather than assembling separates.

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.
