Supports DSD512 Native, PCM 768kHz\/32bit, and DoP64 \/ 192kHz optical \u0026amp; coaxial. An OPA1612-stabilized DAC reference ensures accuracy, achieving THD+N –120dB.\u003c\/li\u003e\n\u003cli\u003eEquipped with an ultra-low-noise linear power supply with only 40nV ripple and a star-shaped voltage distribution circuit that separates digital and analog power paths. Premium components including gold-plated connectors and OCC silver-plated wiring help maintain exceptional clarity, resolution, and dynamic performance.\u003c\/li\u003e\n\u003cli\u003eThe entire signal chain is fully balanced, from DAC decoding to IV conversion and LPF filtering. The R2R volume control system includes 20 Omron micro relays and 88 precision metal-film resistors, delivering up to 1024 ultra-fine steps for smooth volume transitions and 0.1dB left–right channel balance. Functions as a reference-grade DAC, headphone amplifier, and preamplifier with accurate imaging and an immersive listening experience.\u003c\/li\u003e\n\u003cli\u003eThe X9 introduces HP-EQ, a hardware-level headphone equalization system that adjusts in real time based on each headphone’s frequency response to achieve a Harman-aligned sound signature. It supports creating and sharing custom EQ profiles, backed by a database of 2500+ headphone models. Features include automatic impedance detection with intelligent gain recommendation, digital crossfeed for natural speaker-like presentation, and adjustable soundstage, all processed digitally with zero added distortion.\u003c\/li\u003e\n\u003cli\u003eBuilt with high-end WIMA capacitors, premium electrolytic and non-polar capacitors, and 0.1% precision resistors. The 4.0-inch 1080P touchscreen and 15° diamond-cut front panel ensure intuitive and comfortable interaction, while the CNC-machined aluminum chassis provides durability and excellent heat dissipation. Connectivity includes HDMI ARC, USB-B\/USB-C, optical, coaxial, analog inputs, dual sub outputs, and a 12V trigger. Supports IR remote, wireless phone\/PC control, and OTA firmware updates.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Brand: luxsin","offers":[{"title":"Default Title","offer_id":48285959487709,"sku":"B0G43B5NGQ","price":1824.34,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0834\/3381\/6285\/files\/31n9lPpdx0L.jpg?v=1785494053","url":"https:\/\/listenora.us\/products\/luxsin-x9-desktop-dac-headphone-amplifier-ak4191-ak4499ex-hp-eq-crossfeed-dsd512-pcm-768khz-32bit-app-web-ui-wireless-control-with-remote-controller","provider":"Listenora","version":"1.0","type":"link"}
