Cyrus 40 ST Network Streamer
A Serious Digital Front End for Serious Listening
The Cyrus 40 ST is a high performance network streamer designed for listeners who care deeply about how digital audio is handled, not just how convenient it is. Built in the UK as part of the Cyrus 40 Series, it is engineered to be a dedicated digital source that prioritises signal integrity, timing and long-term system quality.
This is not a streamer designed to do everything casually. It is designed to do one thing properly: deliver clean, stable, high quality digital audio to the rest of your system.
Streaming Done the Cyrus Way
Cyrus approaches streaming as a source component, not a feature. The 40 ST is built around a carefully designed digital platform with a focus on low noise operation, accurate clocking and reliable long-term performance.
The result is a presentation that is controlled, detailed and musically coherent, without the glare or brittleness that lesser digital sources can introduce.
Designed to Be the Digital Heart of a System
The 40 ST is designed to integrate cleanly into high quality stereo systems. Used as a streamer feeding an external DAC or paired with Cyrus amplification and digital conversion, it acts as a stable, low noise digital transport.
Built for Longevity, Not Trends
Like other Cyrus components, the 40 ST is designed with longevity in mind. Firmware updates allow the platform to evolve over time, while the robust hardware design ensures stable performance year after year.
