Innuos Next-Gen FLOW EMM Labs Optilink Module

EMM Labs created Optilink, an optical interface, so its DACs could receive music as light, electrically isolated from everything upstream. The Optilink Module gives the Innuos Next-Gen FLOW that native connection, so your EMM Labs DAC receives a precisely reclocked signal through the input its designers built it around.

Your EMM Labs DAC, fed in its own language.

The Design

The Next-Gen FLOW is a dedicated USB master reclocker. It takes the USB signal from your server, discards its timing, and rebuilds it against a reference-grade 3ppb OCXO, the same clock Innuos uses in its flagship NazaréFLOW. Its power supply pairs a 300VA transformer with ARC6 active rectification, and CX regulators feed both the clock and the module section, so the output module works from clean, dedicated power.

The Optilink Module is the final link. It takes the FLOW's reclocked signal and delivers it to your EMM Labs DAC over Optilink. Because the connection is optical, the electrical path between source and DAC is broken, keeping ground noise from the rest of the system away from the converter.

How It Sounds

The Next-Gen FLOW brings the reclocking concept of Innuos's flagship NazaréFLOW to the ZEN Next-Gen series, and Innuos describes the result as greater focus, realism, and accuracy. We'll share our own impressions as soon as we've spent time with it.

Where It Fits

This module is for EMM Labs owners who want an Innuos source chain that ends in EMM Labs' preferred input. The FLOW works with any USB source and is designed to match the ZEN Next-Gen, ZENith Next-Gen, and STATEMENT. Pair it with the Next-Gen NET switch and the whole chain, from network to DAC, is built for the same goal.

Innuos also offers FLOW modules for MSB (ProISL), CH Precision (CH-Link), and Soulution and other HDMI I2S DACs. Before you order, confirm your EMM Labs DAC has an Optilink input. Tell us your model and we'll check it with you.

Press Recognition

The Next-Gen FLOW and its modules debuted at HIGH END Vienna in June 2026, and reviews are on the way. We'll add them here as they're published. Read the launch coverage at The Absolute Sound
