Shenzhen, China – Premium audio brand D&A has officially launched its flagship product, the Alpha PRO Full-Function Hi-Fi DAC/Headphone Amplifier. It represents not only a culmination of cutting-edge technologies but also a physical manifestation of the "Future Design" philosophy, crafted to build a pure bridge between digital and analog worlds for audio connoisseurs.
Precision Architecture Redefining Performance Standards
The Alpha PRO is equipped with the ESS flagship ES9039MSPRO DAC chip, deeply integrated with D&A's self-developed "SIGMA DAC" architecture and 4C-FBDA fully-balanced discrete amplification circuit. The core innovation lies in combining the ultra-low jitter (15ps typical) of a femtosecond-grade clock system with the ultra-low distortion (0.0001%) of a fully-balanced architecture, achieving a lossless signal path from source to output. This delivers robust 6000mW+6000mW driving power for headphones ranging from 16Ω to 600Ω.
Transparent Aesthetics: Where Technology Gains Warmth
The Alpha PRO utilizes a multi-layered construction with translucent materials as the front panel and anodized aluminum, creating a unique dialogue between light and shadow. As light passes through its precise internal structures, it reveals the distinctive beauty of acoustic engineering. The Intelligent Light Interaction Array transforms device status into dynamic visual cues, turning every operation into a visual conversation with technology. This design language, what D&A calls "Future Design," achieves perfect balance between rational engineering and sensory aesthetics.
Omni-Scenario Application, Seamless Digital Integration
As the core of any audio system, the Alpha PRO offers unprecedented connectivity flexibility:
High-Resolution Bluetooth: Qualcomm QCC5125 chip supporting LDAC 24bit/96kHz and other high-quality codecs
Comprehensive Interface Support: USB-C, Optical, Coaxial, and Analog inputs, compatible with traditional devices like turntables
True Preamplifier Function: Built-in high-performance analog volume control, operable as a standalone preamplifier
Key Product Highlights:
Core Decoding: ES9039MSPRO flagship DAC, supporting DSD512 & PCM 768kHz/32bit
Amplification Circuit: Self-developed 4C-FBDA fully-balanced discrete architecture, 32-transistor current amplification
Clock System: 2-stage PLL + 3 femtosecond oscillators, eliminating timing errors
Power Design: Discrete linear regulated power supply, Mean Well power module, dual input filtering
Design Language: Multi-layer transparent structure, anodized aluminum chassis, intelligent light interaction
The Alpha PRO is now officially available at an MSRP of ＄699 USD. It can be purchased through authorized distributors.
