TANCHJIM LUNA Portable USB HiFi Headphone Amplifier Dual CS43198 DAC 32-Bit768kHz & DSD256 Support 4.4mm & 3.5mm Outputs Compatible with

[High-Performance Dual DAC Chips, High-Fidelity Sound Quality] LUNA is equipped with two CS43198 DAC audio decoding chips, commonly found in flagship players. Separate op-amp chips are used for the left and right channels, providing superior resolution. The signal-to-noise ratio (SNR) exceeds 132dB, the signal-to-distortion ratio (SINAD) reaches 118.5dB, and the distortion rate is a mere 0.000139%. Supporting high-resolution 32-bit/768kHz and DSD256 audio, the LUNA delivers high-quality sound reproduction, allowing you to hear more details. [Output Performance of Flagship Players] LUNA uses a high-performance independent power supply architecture, providing ultra-low noise positive and negative power supplies and low-dropout linear regulator technology. This allows for high-precision, high-output current drive, delivering powerful, concentrated sound comparable to flagship players. [Dual Output Terminals] LUNA features a 3.5mm single-ended and 4.4mm balanced output terminals, making it compatible with a wide range of earphones. The included Type-C cable makes LUNA compatible with a wide range of mainstream devices, including Android smartphones, iPhones, iPads, PCs, and laptops. LUNA's housing is machined from a single piece of aircraft-grade aluminum alloy, making it durable and shock-resistant. [Switchable DAC Output Stage Amplification Modes] LUNA's DAC output operating mode can be switched between Class AB and Class H modes. Class AB amplifiers are widely used in the high-fidelity audio field due to their excellent linearity and stability, while Class H amplifiers have relatively high efficiency. Users can switch between DAC amplification modes according to their actual needs. [High-Purity Single-Crystal Copper-Silver-Plated Cable Core Material] The USB 2.0 Type-C cable included with LUNA uses single-crystal copper-silver-plated material for the cable core. The digital signal transmission line and power supply line are shielded independently with a copper-silver-plated shielding layer, then run parallel to each other. This design provides stronger transmission capabilities and superior interference resistance and shielding compared to unshielded braided cables.
