Luna Portable Headphone Amplifier High-Resolution USB DAC Decoder

[High-Performance Dual DAC Chip, High-Fidelity Sound Quality] LUNA features two CS43198 DAC audio decoding chips, commonly used in flagship-level players. It employs independent op-amp chips for each left and right channel, achieving higher resolution. The signal-to-noise ratio (SNR) exceeds 132dB, while the signal-to-intermodulation distortion ratio (SINAD) reaches 118.5 dB, keeping distortion at a mere 0.000139 %. Supporting high-resolution 32-bit/768kHz and DSD256 playback. [Flagship-Class Player Output Performance] LUNA employs a high-performance independent power supply architecture, delivering ultra-low-noise positive and negative power supplies, along with low-dropout linear regulator technology. This enables high-precision, high-output current drive, delivering powerful, concentrated sound comparable to flagship-class players.

[Dual Output Terminals] LUNA features a 3.5 mm single-ended output and a 4.4 mm balanced output, making it compatible with a wide range of earphones. The included Type-C cable ensures LUNA is compatible with a wider range of mainstream devices. It can be used with Android smartphones, iPhones, iPads, PCs, laptops, and more. LUNA's chassis is precision-machined from a single piece of aircraft-grade aluminum alloy, making it robust and highly impact-resistant. [Switchable DAC Output Stage Amplification Mode] LUNA's DAC output can be switched between Class AB and Class H modes.

Class AB amplifiers are widely used in the hi-fi audio field due to their excellent linear characteristics and stability. Class H amplifiers, on the other hand, offer relatively high efficiency. Users can switch the DAC amplification mode to suit their needs. [High-Purity Single-Crystal Copper Silver-Plated Cable Core Material] The USB 2.0 Type-C cable included with LUNA employs single-crystal copper silver-plated material for its cable core. Structurally, the digital signal transmission lines and power supply lines are independently shielded by a copper-silver-plated shield layer and then arranged in parallel, achieving superior interference resistance and shielding effectiveness
