FangSound Prometheus
Flagship ESS ES9039PRO DAC
Built around the flagship ESS ES9039PRO DAC, renowned for its wide dynamic range and low distortion, Prometheus delivers a clean sonic foundation for precise layering, accurate imaging, and a convincing sense of space. More than a flagship component, the ES9039PRO provides a high-fidelity signal foundation for the powerful headphone amplification stage, supporting both sonic precision and dynamic authority. With high-resolution audio, subtle overtones and ambient reverberation are reproduced with greater nuance, bringing together exceptional detail retrieval and an engaging, natural musical presentation.
Powerful Headphone Amplification, 0.8W per Channel into 32Ω
Prometheus features a high-current output stage and low-output-impedance design, delivering up to 800mW per channel into a 32Ω load without requiring an external power supply. This combination of portability and powerful amplification brings substantial driving capability to a compact form. Its high-performance amplification architecture provides ample dynamic headroom and excellent transient response, maintaining precise control, solid bass reproduction, and clear dynamic layering across a range of headphone loads and demanding musical passages.
Up to 32-bit / 768kHz PCM High-Resolution Audio Support
Prometheus supports PCM audio decoding up to 32-bit/768kHz, delivering the high-resolution audio compatibility required for demanding digital music playback. Combined with the flagship ESS ES9039PRO DAC, renowned for its wide dynamic range and low distortion, Prometheus is engineered to bring out the full potential of high-resolution recordings, revealing fine musical details, dynamic contrasts, and subtle nuances with precision.
Compact, Portable Design
Prometheus brings flagship-level audio engineering into a remarkably compact, portable design. Through high-density circuit integration, precision component placement, and optimized thermal management, its sophisticated power supply and high-performance amplification circuits work in harmony within a limited footprint, delivering powerful headphone drive without compromising portability.
Precision-Machined Aluminum Chassis
Machined from a solid block of aluminum alloy using precision CNC machining, the chassis delivers excellent structural rigidity and efficient heat dissipation. The integrated one-piece enclosure minimizes seams and joints, enhancing shielding continuity and long-term durability while reducing the risk of loosening over time. The anodized surface offers a refined tactile feel and enhanced resistance to everyday wear and scratches.
System-Level Noise Immunity and Stability
Built on system-level circuit optimization, Prometheus features a carefully engineered power supply architecture and meticulously designed digital and analog signal paths. Thoughtful circuit partitioning, optimized signal routing, and shielding measures help suppress interference and noise, preserving signal integrity and sonic purity. Combined with efficient thermal management and system-wide stability measures, this design helps maintain consistent output and linear performance under sustained, demanding operating conditions, delivering a clean sonic background, precise imaging, and a natural, coherent soundstage.
Efficient Thermal Management System
Prometheus features a carefully engineered thermal management system built around a high-thermal-conductivity aluminum alloy chassis. Combined with optimized internal heat-transfer paths, this design efficiently draws heat away from key components and distributes it evenly throughout the chassis. Through precise optimization of the chassis structure, enclosure wall thickness, and thermal layout, Prometheus balances heat dissipation efficiency, structural rigidity, and user comfort, helping maintain reliable operation for extended listening sessions.
Precision in Every Detail
Reinforced connector areas and anti-loosening measures help reduce mechanical stress from repeated use over time. Meticulous component selection and high-quality soldering workmanship help minimize potential sources of intermittent noise. Branding elements and chamfered edges follow a cohesive, understated aesthetic, where visual harmony and tactile refinement matter equally.
