We're Digi & Aesth, a new brand dedicated to high-end audio design. Rooted in our philosophy of "Future Design", we aim to fuse cutting-edge engineering with timeless aesthetics — where digital precision meets artistic expression.
The Alpha PRO is our very first creation: a fully balanced, high-fidelity DAC Amp built from the ground up to push the boundaries of desktop audio. From flagship decoding to discrete amplification, every part is crafted to deliver a pure, powerful, and refined listening experience.
Flagship Decoding Engine
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).
Built for perfect reproduction
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.
Precision-Engineered Synergy
Dual-DomainIsolation 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.
Premium Circuit
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.
No Headphone Beyond Reach
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.
Multiple output modes
