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:

• 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:

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.
