Silent Angel Genesis GC-25M Master-Clock

The Silent Angel Genesis GC-25M is an external 25 MHz master clock that gives Silent Angel devices with a 25 MHz clock input a more precise timing reference.

Timing is everything in digital audio. The GC-25M gives your chain a clean, stable reference that everything else can lock onto.

Why the GC-25M?

The more precise the clock, the calmer the data stream, and the more relaxed the sound.

• External 25 MHz reference: A dedicated, high-precision clock replaces the internal clock of compatible devices and lowers jitter.
• Targeted upgrade: Built for the Bonn N8C, Bonn NX and Rhein Z1 Plus models with a 25 MHz clock input, as a clean expansion step for an existing Silent Angel chain.
• More calm in the sound: Fewer timing errors mean more air between instruments and a more stable soundstage.

What you hear

The effect shows up as extra calm and order: instruments stand out more clearly in space, fine details resolve more cleanly. Most noticeable on an already high-quality digital chain that's otherwise fully dialed in.

Who is the GC-25M for?

The GC-25M is for owners of compatible Silent Angel devices who want to extract that last bit of precision. Bottom line: without the right clock input it does nothing, and on a simple chain the effort outweighs the gain. In the right setup, it's the logical next step.

Our verdict

A targeted timing upgrade for an already well-set-up Silent Angel chain. Whether the GC-25M is worth it for you and fits your devices, we're happy to work that out openly with you at HD Zürisee in Wädenswil.

Frequently asked questions

What do I need the GC-25M for?

The GC-25M delivers an external 25 MHz reference clock for compatible Silent Angel devices. A more precise clock reduces jitter, the finest timing errors in the data stream, resulting in a calmer, more clearly defined sound.

Which devices can I connect it to?

The GC-25M is built for Silent Angel components with a 25 MHz clock input, including Bonn N8C, Bonn NX and Rhein Z1 Plus. We'll check with you whether your device has the right input before you invest.

Does an external clock make an audible difference?

On an already high-quality digital chain, yes, in the form of more calm and air between instruments. On a simpler system the effect is more subtle. We're honest about this rather than promising miracles.

Why buy the GC-25M at HD Zürisee?

Because external clocking takes experience and the right cabling. At our store in Wädenswil we sort out compatibility, benefit and integration, looking at your whole chain rather than a single component.
