D-15000 OTL/OCL

介绍

The Pinnacle of Full-Tube DACs Featuring the ES9039PRO Overview – Engineering Purity, Elevating Emotion The Allnic D-15000 is not a mere update; it is a complete reimagining of the full-tube DAC concept. As the rightful successor to the acclaimed D-10000, the D-15000 fully embraces the I²S audio era while maintaining Allnic’s analog mastery and next-generation digital precision. At its core: A fully tube-based OTL/OCL analog output stage for exceptional clarity Dual-mono ES9039PRO DACs featuring ESS’s latest HyperStream IV architecture While I²S input support ensures future-proof versatility, the D-15000 delivers outstanding performance across all inputs, including USB and S/PDIF, making it an exceptional partner for every source. Core Technologies 🔹 Allnic’s Dual Design Philosophy: OTL/OCL & Permalloy Allnic pioneered two distinct output stage philosophies: OTL (Output Transformer-Less) / OCL (Output Capacitor-Less) – delivering a direct, transparent tube sound free of coloration. Permalloy output transformers – still used in other Allnic products for their musicality and tonal richness. The D-15000 exemplifies the OTL/OCL approach, achieving unparalleled purity and dynamic expressiveness. 🔹 Dual ES9039PRO DACs Two of ESS’s flagship DACs are configured in a fully balanced dual-mono layout, utilizing the latest HyperStream IV architecture. → Result: stunning resolution, ultra-low distortion, and impeccable channel separation. 🔹 Independent Power Supply Architecture The D-15000 employs completely separate power transformers for the digital and analog circuits, eliminating interference at its source. Benefits include: • Dramatically lower noise floor • Ripple-free, stable voltage supply • Wide, natural dynamic range • Tailored regulation optimized for each circuit 🔹 Galvanic Isolation Physical isolation between digital and analog domains prevents high-speed noise and jitter from contaminating the analog signal path. When combined with transformer separation: • Total noise immunity • Enhanced micro-detail and image depth • A truly black background and expansive soundstage 🔹 Flexible Sound Tuning Thanks to its transparent architecture, the D-15000 responds beautifully to changes in upstream components, cables, and limited tube rolling. This flexibility allows audiophiles to fine-tune its sound to perfectly match their system, and even reveals issues in other components, making it an insightful partner in pursuing ultimate audio quality. Listening Impressions – Freedom for Every Format Whether it’s SACD, high-resolution streaming, or classic Red Book CDs, the D-15000 delivers an immediate, engaging, and deeply lifelike sound. ✔ Crystal-clear resolution ✔ Effortless dynamics ✔ 3D holographic imaging with physical presence “Even during complex, fast-paced passages, the sound remains focused, fluid, and alive — a result only achievable with transformer-less topology.” The D-15000 is equally remarkable across all genres, from classical and jazz to electronic music, revealing both detail and emotional nuance without imposing coloration. Design & Build – Purposeful Elegance Every physical element of the D-15000 reflects Allnic’s commitment to performance: Massive side-mounted heat sinks stabilize temperature-sensitive ES9039PRO chips • Front-panel switches allow intuitive selection of inputs and clock sources • Spacious rear panel simplifies high-end system integration • Rigid all-metal chassis ensures EMI/RFI shielding and structural resonance control Form and function merge seamlessly in a design that is as beautiful as it is purposeful. Conclusion – Precision Meets Emotion The Allnic D-15000 is more than a DAC — it is a declaration of audio integrity. SACDs, high-resolution streaming, and PCM sources alike are liberated with breathtaking fidelity. Technology meets emotion. Precision meets artistry. The D-15000 redefines what a full-tube DAC can be.
