About this item

• 【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. Our "SIGMA DAC" topology employs 8-channel differential signal summation per channel, reducing output impedance by 4x and noise by 75%, achieving unmatched dynamic range (133dB) and THD+N(-124dB).
• 【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 16Ω-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.
• 【Analog Input】 A groundbreaking analog input circuit supports turntables and tape decks, serving as a standalone preamplifier for 90%+ legacy audio systems. *Note: Requires phono preamp-enabled turntables.
• 【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.
• 【Built for perfect reproduction】 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.
