A diamond-cut bevel panel frames a large laminated display, while the all-CNC aluminum chassis is built for robust thermal performance. Inside, Luxsin specifies audiophile components throughout—WIMA capacitors, gold-plated electrolytics, non-polar film caps, 0.1% low-drift resistors, OCC silver-plated internal wiring, gold-plated connectors, and a femtosecond clock—aimed at lowering noise and preserving detail.\u003c\/p\u003e\n\u003cp\u003eCore signal processing centers on the AK4499EX DAC with OPA1612 stabilization, a star-routed power architecture that separates digital and analog rails, and quoted ripple disturbance as low as 40 nV. The fully differential path runs end-to-end—AK4499EX to OPA1612 IV, LPF, balanced R2R volume control, dynamic negative feedback stage, and the 6120A2 headphone amplifier—targeting THD+N of −120 dB for high resolution, clarity, and drive. A self-developed headphone impedance self-test recommends the appropriate maximum output level, and available power is rated up to 6,000 mW for versatile headphone control.\u003c\/p\u003e\n\u003cp\u003eUser features are equally ambitious. HP-EQ applies headphone-specific correction toward an idealized Harman target, drawing on a continuously updated database of 2,500+ models. Digital crossfeed provides a more speaker-like presentation for long sessions, and you can digitally adjust soundstage depth and width for precise imaging control without analog coloration. A 4\" 1080p touchscreen runs an automotive-grade RTOS for responsive setup, on-device personalization (including multiple VU meter styles), OTA firmware updates, and wireless remote support.\u003c\/p\u003e\n\u003ch3\u003eIn The Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Cable \u003c\/li\u003e\n\u003cli\u003eRemote Controller \u003c\/li\u003e\n\u003cli\u003eUSB-B Cable \u003c\/li\u003e\n\u003cli\u003eType-C OTG Cable \u003c\/li\u003e\n\u003cli\u003eUser Manual \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eDAC Chip:\u003c\/b\u003e AK4191EQ + AK4499EX\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAudio Processor:\u003c\/b\u003e AKM 7739 DSP\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOp-Amp Chip:\u003c\/b\u003e OPA1612\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eSupported Formats:\u003c\/b\u003e DSD512; PCM up to 768 kHz \/ 32-bit\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eBluetooth Audio Input:\u003c\/b\u003e Bluetooth 5.0 (AAC, SBC)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eUSB-B Audio Input:\u003c\/b\u003e Windows (10, 11), Android, iOS; supports DSD512 and PCM up to 768 kHz \/ 32-bit\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOptical\/Coaxial Audio Input:\u003c\/b\u003e PCM up to 192 kHz \/ 24-bit; DoP64\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHDMI ARC:\u003c\/b\u003e PCM up to 192 kHz \/ 24-bit\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnalog Input:\u003c\/b\u003e RCA (unbalanced); maximum gain +10 dB\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eAnalog Audio Outputs:\u003c\/b\u003e XLR (balanced), RCA (unbalanced), subwoofer output\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eXLR Output Level:\u003c\/b\u003e 4.2 Vrms @ 0 dBFS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRCA Output Level:\u003c\/b\u003e 2.1 Vrms @ 0 dBFS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHeadphone Output Level:\u003c\/b\u003e 4–15 Vrms @ 0 dBFS\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDisplay:\u003c\/b\u003e 4\" TFT fully laminated touchscreen (960 x 400)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003ePower Supply:\u003c\/b\u003e Ultra-low-noise linear power supply\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eRated Power:\u003c\/b\u003e 25 W\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eDimensions (WHD):\u003c\/b\u003e 11.8\" x 2.6\" x 8.1\" (300 x 65 x 206 mm)\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWeight:\u003c\/b\u003e 8.2 lb.
