YinLvMei A2 (Black) (Sold Out)
A2 uses 2 piece AK4497 DAC chips to improve resolution, density and resolution. The peripheral uses 14x 100UF + 4 x 220UF Panasonic low-ESR polymer tantalum capacitors and 2x OPA1642 to achieve high-quality fully balanced output.
Customized opamp and power tube
A2 uses customized special tuning dual op amps + 8x power tubes. Working in Class A state, the sound is warm and delicate, and has 4 gain adjustments to achieve full compatibility of high, medium and low impedance headphones, and the headphone port uses NEC High quality relay.
Quad-core 64-bit MTK processor
Based on the A1S, A2 has replaced a new platform and upgraded the MTK processor. It runs 200% faster and ensures smooth control.
Asynchronous USB processor with High-precision clock
A2 has a built-in asynchronous USB chip SA9227, which realizes digital rearrangement and exclusive output. With 3 high-precision low-jitter clock crystals, the clock is more accurate and the sound quality is more advanced. SA9227 can also be used as a professional USB DAC.
PGA4311 volume system
A2 uses the most luxurious volume control system-digital analog volume, which solves the problem of low volume deviation and short life of traditional analog potentiometers, and avoids the problem of pure digital volume compression dynamics.
