Three Legends. One Perfect Stream.
The modern DAC landscape is dominated by design optimised for measurement performance and large-scale integration. This is success from an engineering perspective, not a listening one. The Ingenii was therefore engineered from a singular premise - to preserve the musical integrity of digital replay through structural prevention as opposed downstream correction - addressing degradation at its origin. Each stage is electrically isolated, mechanically controlled, and functionally independent. There is no “house” sound; only what can be achieved if cost is not a consideration.
Craftsmanship
Tri-Architecture Conversion System.
Ingenii recognises that conversion itself carries aesthetic consequence. It therefore unites three legendary conversion topologies, each architecturally distinct: Philips TDA1541A with Dynamic Element Matching - for a romantically musical presentation. Analog Devices AD1862 (R2R) - for detailed, airy, and dynamic sound. DSD-Direct Stonehenge Architecture - for seamless liquidity and flow. Through Bit-Gravity™ control, the listener can dynamically allocate bit-weighting across conversion domains, shaping the balance of reconstruction without damaging signal integrity.

A Physical Architecture of Silence.
Ingenii’s composite chassis inherits Luna’s material philosophy of copper, aluminium, polymer isolation, and vibration-dissipating layers to control resonance and electromagnetic exposure.
Signal Preparation, Without Interpretation
Digital Mastering™.
Before conversion begins, the Ingenii prepares the incoming signal through its proprietary Digital Mastering™ architecture. Seven selectable filter profiles, three DSD Remastering modes, and optional enhancement algorithms allow transient behaviour, time-domain reconstruction, and harmonic integrity to be optimised before the conversion stage itself. The objective is not to alter the music, but to prepare it for the most faithful possible reconstruction.
Three Legendary Conversion Paths
Tri-Architecture DAC System.
Ingenii rejects the notion that a single conversion architecture can excel in every aspect of musical reproduction. Instead, it combines three fundamentally different conversion domains: the Philips TDA1541A with Dynamic Element Matching for natural tonal density, the Analog Devices AD1862 R-2R architecture for detail and dynamic precision, and the proprietary DSD-Direct™ Stonehenge Architecture for seamless liquidity and flow. Each topology contributes its own strengths to the reconstruction process.
Selectable Analogue Identity
Output Voicing Architecture.
Following conversion, Ingenii employs a passive silver-tantalum I/V stage designed to avoid imposing character onto the signal. The listener can then define the final presentation through selectable valve or Class-A FET amplification stages, with both balanced and single-ended outputs available. Rather than enforcing a fixed sonic signature, Ingenii allows the analogue character of the system to be tailored while preserving signal integrity.
Detached From The Mains
AirLock™ Power Architecture.
Ingenii's AirLock™ system applies the principles of an airlock to electrical power delivery. Energy is stored within an isolated reservoir before being completely decoupled from the mains during playback. The audio circuitry therefore operates free from live supply interaction, preventing mains-borne noise, charging artefacts, and electrical contamination from reaching the signal path. Power is separated from playback by design, not managed within it.
Technical Excellence
Coherence Across Every Domain.
Ingenii treats digital replay as a complete system rather than a single conversion chip. Digital preparation, PCM and DSD conversion, clocking, power isolation, analogue output, internal wiring, and mechanical construction are each controlled as separate domains, then brought together through one disciplined architecture. The result is a DAC platform designed to preserve format identity, timing stability, low-level information, and analogue integrity without forcing every recording through one fixed conversion philosophy.

Internal Signal Wiring
Every format keeps its identity.
PCM is preserved as PCM unless remastering is selected. DSD is decoded through its own dedicated path. Ingenii does not hide conversion decisions - it makes them part of the architecture.
Precision, without sameness.
Bit-Gravity™ allows PCM reconstruction to move between different multibit behaviours, giving the listener meaningful control without relying on EQ, DSP voicing, or post-processing effects.
Quietness you can feel.
By controlling power, clocking, mechanical behaviour, and internal interfaces as separate domains, Ingenii reduces the low-level instability that can make digital playback sound restless or fatiguing.
