This fully-balanced DAC/Amp delivers 2000mW of power, a top-of-the-line ESS DAC chip, a Class-A buffer, and full MQA support. Compact yet packed with high-end components, the XA-02 is your key to precise yet natural sound, whether you're listening through headphones or using it as a preamp for powered speakers. \nFully-balanced output\nSayonara, crosstalk and noise. The XA-02's balanced design extends from the decoding stage all the way through the amp circuit. By keeping the signal paths separate, it majorly reduces interference caused by ground loops and channel crosstalk, leaving you with clear, isolated sound. \nPower for every headphone\nWhether you’re driving sensitive IEMs or high-impedance headphones, the XA-02 has you covered. It features 910mW output through the 6.35mm jack and an impressive 2000mW through the 4.4mm balanced output.\nAll your favorite formats\nWith support for full MQA, DSD256, PCM, and DXD, the XA-02 gives you access to the highest-resolution audio available. Whether you're streaming, downloading, or using a Hi-Fi player, this DAC/Amp has the flexibility you need.\nSuper low distortion\nDistortion? Not here. With a THD+N of just 0.0005% and a signal-to-noise ratio of 121dB, you’re going to have a hard time hearing anything other than the music. \nConnect anything\nUSB, coaxial, optical, Bluetooth—whatever you’re using, the XA-02 is ready for it. Bluetooth support includes all the popular codecs like aptX, LDAC, and AAC, so you don’t have to sacrifice quality for convenience.\nClass-A buffer for powerful output\nBy using transistors in a Class A buffer, the XA-02 ensures that the circuit stays in its optimal operating range. This not only maximizes performance but also allows the amp to handle a wide range of headphone loads with ease, giving you powerful, consistent sound.\nBuilt for au","images":["https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606129156332.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606129189100.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128664812.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128468204.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128402668.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128599276.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128795884.jpg?v=1741110866","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128337132.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128369900.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128632044.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128828652.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128566508.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128500972.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128435436.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128304364.jpg?v=1741110867","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128730348.jpg?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128763116.jpg?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128533740.png?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606128697580.png?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606129123564.jpg?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606129221868.jpg?v=1741110868","https://cdn.shopify.com/s/files/1/0225/2721/3642/files/apos-audio-xduoo-headphone-dac-amp-xduoo-xa-02-balanced-desktop-dac-amp-41606129058028.jpg?v=1741110868"],"price":199,"currency":"USD","in_stock":true,"inventory_qty":9999,"dynamic_pricing":false,"listed_at":"2026-06-20T16:25:58.141Z"},"share_url":"https://firestarter.network/l/lst_ZN3b4RNL","purchase":{"summary":"Live product listing on the Firestarter agent commerce network.
