{"product_id":"smsl-d400-pro","title":"SMSL D400 Pro Desktop DAC","description":"\u003cp\u003eThe SMSL D400 Pro is a full-size desktop DAC built around the AK4191 modulator paired with the AK4499EX converter — the Velvet Sound split-architecture approach — with an XMOS XU316 handling USB. It's aimed at desktop listeners assembling a proper source-first chain rather than a plug-and-go dongle setup.\u003c\/p\u003e\u003cp\u003eInputs cover optical and coaxial alongside USB, plus Bluetooth, and it decodes up to 32bit\/768kHz PCM and DSD512 with MQA-CD support. Remote control means it works just as well parked in a rack feeding a power amp as it does on a desk in front of a headphone amp. Pair it with a balanced headphone amplifier or active monitors and let the D400 Pro be the fixed reference point in the system.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAK4191 + AK4499EX DAC architecture\u003c\/li\u003e\n\u003cli\u003eXMOS XU316 USB interface\u003c\/li\u003e\n\u003cli\u003eDSD512 and 32bit\/768kHz PCM support\u003c\/li\u003e\n\u003cli\u003eOptical, coaxial, and Bluetooth inputs; MQA-CD\u003c\/li\u003e\n\u003cli\u003eIncluded remote control\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMSL","offers":[{"title":"Black","offer_id":45376989429895,"sku":"SMSL D400 Pro-black","price":553.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0756\/5833\/0247\/files\/7505193443.jpg?v=1785502836","url":"https:\/\/tonepier.com\/products\/smsl-d400-pro","provider":"TonePier","version":"1.0","type":"link"}
