【ES9039MSPRO Flagship DAC chip】Harnessing ESS's flagship ES9039MSPRO DAC with MQA hardware decoding. HyperStream technology, and fully isolated digital/analog processing, the Alpha Pro eliminates jitter via 32-bit noise shaping and proprietary"Zero-Jitter Clock" architecture.
【4C-FBDA Fully Balanced Discrete Amplification】Featuring 32 discrete transistors across four channels, the 4C-FBDA circuit achieves <0.1Ω output impedance and 0.0001% THD.Effortlessly driving 160-600Ω headphones. it delivers 6000mW+6000mW at 32Ω with zero dynamic compression.
【Pure Preamplifier Function】Equipped with NJU72315 analog volume control-the industry's highest-performance chip-Alpha Pro eliminates micro-detail loss at low volumes while attenuating external noise.
【Dual-Domain Isolation Architecture】Digital and analog modules are physically segregated via 4-layer PCB isolation and independent ground planes. Shielded blocks and star-quad power routing ensure zero crosstalk between DSP processing and DAC conversion.
【2nd PLL Clock + 3 Femtosecond Oscillators】Three femtosecond-grade oscillators-two for local UsB clocks and one VCXO for the 2nd PLL-slash jitter to 15ps (10x lower than conventional designs), ensuring sharper imaging. Better detail, and a more natural sound across every input.
【Signal Integrity-Driven Partitioning Strategy】Critical traces are sandwiched between guarded layers, forming electromagnetic "Faraday Cages" +5ps delay matching and star-ground topology isolate digital control, high-speed data.analog audio, and power domains.
