Built around a dual WM8741 DAC chip design and voiced by xDuoo, this module leans into rich harmonics and natural tonality—perfect for long nights with old favorites and new classics. \nBuilt for Blue Note nights\nThere’s something about the WM8741 that fits jazz like a glove. It’s smooth without smearing, rich without bloat, and detailed without coldness. The voicing walks a careful line—one that doesn’t sound analytical, but human.\nTube sound minus the tubes\nThis DAC card has a subtle touch of what some call \"tube character\"—a slightly softened top end, a rounder midrange, and a warm sense of body. It doesn’t color everything, but it brings classic recordings to life in a way that can feel a bit closer to vinyl. \nDual WM8741 chips for natural depth\nUsing two WM8741 DAC chips in a balanced configuration, this card delivers strong dynamic range, high signal-to-noise ratio, and excellent separation. \nProduct highlights\n\nDual WM8741 DAC chips for natural, balanced sound\nDesigned by xDuoo specifically for the XD05 Pro Hard Nucleus\nVoiced for jazz, classic albums, and smooth analog warmth\nRequires manual MCU firmware update before installation\n\nSpecs\n\nMax Crosstalk: >105dB\nMax THD+N: 0.0007%\nMax SNR: >119dB\n\nWhat’s included\n\nWM8741 DAC Module\n\nTo use with XD05Pro DAC/Amp, please update the firmware","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067855.png?v=1743509682","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067854.png?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067860.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067859.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067858.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067857.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067856.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067867.png?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067866.png?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067864.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067862.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067863.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067861.jpg?v=1753892409","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-wm8741-dac-card-for-xduoo-xd05pro-hard-nucleus-modular-dac-amp-1153067865.jpg?v=1753892409"],"price":199,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:57.701Z"},"share_url":"https://firestarter.network/l/lst_I_ZsUlse","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
