The Allnic D-15000 OTL/OCL is a flagship digital-to-analogue converter that combines state-of-the-art digital processing with Allnic’s expertise in vacuum tube analogue design. Developed as the successor to the D-10000, it integrates dual-mono ESS ES9039PRO DACs with a fully tube-based Output Transformer-Less and Output Capacitor-Less output stage, creating a platform designed to maximise transparency, resolution, and musical expression.

A defining characteristic of the D-15000 is its OTL/OCL analogue output architecture, which removes transformers and coupling capacitors from the signal path to minimise coloration and preserve signal purity. Combined with galvanic isolation, independently regulated analogue and digital power supplies, and dual-mono DAC implementation, the design is engineered to deliver exceptionally low noise, precise channel separation, and wide dynamic range.

Designed for modern digital systems, the D-15000 supports PCM and DSD playback through USB, S/PDIF, and I²S inputs while also incorporating a high-precision OCXO clock and external 10 MHz clock input. The result is a highly sophisticated reference DAC capable of extracting maximum performance from both high-resolution streaming sources and traditional digital transports.
