Innuos NazaréFLOW

The Innuos NazaréFLOW is the final, decisive stage in Innuos's no-compromise digital chain — a Master Reclocker of extraordinary engineering ambition that separates the delicate communication layer from the electrical complexity of the source component and delivers a perfectly synchronised, pristinely regenerated signal to the DAC. Where the Innuos NAZARÉ is the heart of the ultimate Innuos system, the NazaréFLOW is its voice — the component that stands between the server and the DAC and ensures that nothing accumulated in transit survives to colour the music. It works with any source using a USB audio output, and pairs most naturally with the Innuos NAZARÉ — though its benefits extend to any high-end digital source capable of resolving the difference it makes. Complete with the NazaréNET, the full NAZARÉ Stack represents Innuos's ultimate statement in digital audio.

Master Reclocker Circuit and OCXO Clock

Phase noise accumulated across multiple independent clocks is one of the most corrosive problems in a high-end digital system — blurring transients, collapsing spatial information, and undermining the sense of timing and flow that separates great digital audio from merely competent digital audio. The NazaréFLOW resolves this by becoming the single timing reference for the entire communication path: the Master Reclocker.

At the core of the circuit is a high-precision 3ppb OCXO clock, operating on its own dedicated, isolated power rail. By positioning the reclocking stage as close as physically possible to the DAC Connection Module, the NazaréFLOW precisely controls signal transmission, minimises degradation at every point in the chain, and regenerates the signal with a degree of accuracy that no external reclocking solution positioned further from the DAC can match. The DAC Connection Module itself operates in a silent stage — entirely free from computing or processing activity — aligning seamlessly with the DAC's own internal clocking system. Transients are rendered with precision. Spatial cues are fully realised. Music flows with a coherent, effortless sense of realism that reveals, for the first time, precisely what the source material contains.

Modular Output Architecture

The NazaréFLOW ships as standard with an ultra-high-performance USB output stage — already a reference-class solution in its own right. Beyond this, its modular design accommodates optional dedicated DAC Connection Modules, each tailored to a specific DAC's native protocol:

• FLOW ProISL Module — for MSB DACs, using MSB's ProISL protocol
• FLOW CH-Link Module — for CH Precision DACs, using the CH Link protocol
• Further modules are in active development

With these interfaces, the Master Reclocker governs the master clock for PCM/DSD communication, while the DAC contributes the master clocks for the audio signal itself — each clock positioned precisely where it delivers the greatest benefit, optimising the signal path from end to end and removing USB from the chain entirely for owners of MSB or CH Precision DACs.

NAZARÉ-Grade Power Supply

The NazaréFLOW's power supply is engineered to the same exacting standard as the Innuos NAZARÉ — the most advanced power design Innuos has produced. The guiding principle is the minimisation of impedance to extreme levels at every stage, on the basis that the performance of every critical circuit is shaped entirely by the quality of the power feeding it.

Custom-wound multifilar toroidal transformers paired with bespoke Lundahl inductors from Sweden form the first line of defence against mains-borne noise. AC/DC rectification is handled by Innuos's proprietary GaN-ARC8 modules, developed in collaboration with power supply designer Dr Sean Jacobs — gallium nitride switches faster and cleaner than silicon, and is here backed by an energy reservoir of 376,000μF for rapid, low-impedance current delivery under the most demanding dynamic conditions. DC regulation is provided by advanced DC4 modules, also developed with Dr Sean Jacobs, incorporating high-precision foil resistors to maintain ultra-low-noise, low-impedance output that remains stable across the fast transient demands of high-end digital circuitry. Premium internal cabling completes the signal path between each stage.

NAZARÉ Chassis and Vibration Control

The NazaréFLOW shares the chassis philosophy of the NAZARÉ. SmartStack vibration control technology, developed in collaboration with TONEO, is applied across all critical components — transformers, capacitors, regulation modules, and output boards — eliminating the micro-vibrations that would otherwise impose themselves on sensitive circuitry and degrade the signal. The chassis is CNC-machined from 10mm aluminium, providing extensive EMI shielding throughout, with an asymmetric fascia design that breaks up standing waves and reduces resonance. System-tuned isolation feet, developed in collaboration with IsoAcoustics, complete the mechanical picture — ensuring that the internal environment of the NazaréFLOW remains as electrically and mechanically silent as engineering at this level can achieve.

Technical Specifications

Who Is It For?

The NazaréFLOW is for owners of the Innuos NAZARÉ — or any high-end source with a USB audio output — who want to extract the absolute maximum from their DAC. It is particularly compelling for owners of MSB or CH Precision DACs, where the optional native-protocol modules remove USB from the signal path entirely. If you are assembling a no-compromise digital front end and your DAC is capable of resolving the finest detail the source material contains, the NazaréFLOW is the final, indispensable piece.
