Why a Master Clock Matters in a Silent Angel System
A master clock does not make a sound on its own. What it does is give your digital source a cleaner, more stable timing reference, which in turn lets the streamer, server or transport it serves do its own job with less jitter. In a well built Silent Angel system, the Genesis clocks act as the shared heartbeat that keeps everything downstream working from the same low noise reference.

Silent Angel is the network audio specialist brand from Thunder Data, and the Genesis line represents its dedicated clocking tier. If you have already invested in a Silent Angel streamer or server on the VitOS platform, adding an external Genesis clock is one of the most focused ways to refine timing across your chain.
The Shared Genesis Design
Both Genesis models are built around the same core philosophy that runs through the range. The goal is a reference with ultra low phase noise and low jitter, delivered from a high stability oscillator and supported by clean internal power and careful grounding. That combination is what allows a Genesis clock to serve a compatible digital source without adding noise of its own.
Because a clock only benefits gear with an external clock input, both models are intended to pair with Silent Angel streamers, servers, transports and DACs that accept an external reference. Before you choose, it is worth confirming that your source has a clock input and which frequencies it expects.
What They Have in Common
- Purpose built master clock generators for compatible digital sources
- Focus on low phase noise and low jitter timing
- Low noise internal power supply with attention to clean grounding
- Designed to serve Silent Angel VitOS streamers and servers
Comparing the Models
Silent Angel Genesis GC
The Silent Angel Genesis GC is a master clock generator with a 25MHz reference frequency driven by a high stability crystal oscillator. Its design focus is low phase noise and low jitter timing, and it uses a low noise internal power supply with clean grounding. It is built to provide an external clock reference for compatible Silent Angel streamers, transports and servers with a clock input.
The GC is the straightforward entry into the Genesis tier. If your system uses a single compatible source at a fixed reference frequency, the GC gives you a focused, purpose built clock without extra complexity.
Silent Angel Genesis GX
The Silent Angel Genesis GX is a multi frequency reference master clock generator. Its defining design goal is an ultra low phase noise, low jitter reference, and it offers multiple selectable clock frequencies rather than a single fixed output. Like the GC, it serves Silent Angel VitOS streamers and servers, and it is compatible with streamers, servers and DACs that have an external clock input. It sits at the Genesis reference tier.
The GX suits a more flexible setup. Its selectable frequency outputs make it a natural fit when you want a single reference clock that can adapt to different compatible sources or DACs, or when you want the most capable option in the Genesis range as your system grows.
Grouping by Tier and Use Case
The Focused Reference: Genesis GC
Best for a listener who has one compatible Silent Angel source and wants a clean, dedicated timing reference to serve it. The GC is about doing one thing well: providing a stable 25MHz reference from a high stability oscillator with clean power and grounding.
The Flexible Reference: Genesis GX
Best for a listener building a more ambitious or evolving system. With multiple selectable frequencies and an emphasis on ultra low phase noise, the GX is designed to serve a wider variety of compatible streamers, servers and DACs, and to remain relevant as you add or change sources.
Which Should You Buy by Scenario
You have a single Silent Angel streamer or server with a clock input
Start with the Genesis GC. Its fixed 25MHz reference and clean design are aimed squarely at improving the source you already own.
You want one clock that can serve different sources or DACs
Choose the Genesis GX. The selectable frequency outputs give you flexibility to reference a range of compatible gear from a single clock.
You are building toward a reference level VitOS system
The Genesis GX sits at the Genesis reference tier and is the more future minded choice when you anticipate expanding or upgrading the sources it will serve.
You want the most direct, no fuss addition to a single source
The Genesis GC keeps things simple with a dedicated single frequency reference.
A Note on System Matching
Remember that a Genesis clock refines the source it serves, so the ideal partner is a compatible Silent Angel streamer, server or transport on the VitOS platform with a clock input. If you are still assembling your system, it can help to plan the source and the clock together so the reference frequency and connection are matched from the start.
