Ideon Audio eos Stream: Reference Streamer / Music Server
A state-of-the-art, high-performance streamer / music rendering engine
The Ideon Audio eos Stream utilizes trickle-down technologies and R&D gained, from our extensive work with our flagship Absolute Stream. Most of the Absolute Stream’s innovations and designs are found in the eos Stream in its own scale.
The eos Stream introduces significant technology and performance enhancements for rendering music files, including:
- 4TB SSD Internal Storage: Offering ample space for your digital music collection.
- Faster, Enhanced Memory: Doubling the previous capacity for faster and smoother operations.
- Embedded Roon Core: Eliminating the need for an external server running ROON, resulting in improved dynamics, soundstage, and tonal quality due to the superior hardware and ultra-low noise power supplies, already deployed internally.
- Streamlined User Interface: A revamped, simplified interface for Ideon Audio’s native playback software application.
- Qobuz Integration: Seamless integration within Ideon Audio’s native playback software allows users to stream Qobuz music service without requiring additional applications or subscriptions.
The Ideon Audio Design principles
True to Ideon's tradition, the eos Stream is a fully proprietary design incorporating in-house developed audio technologies. Our goal was to create a device delivering dynamic, natural sound that complements the eos DAC, offering a level of musical engagement seldom achieved in digital playback.

Real-Time core playback
Core CPU highly prioritized for audio playback only, ensuring optimized performance and sound quality (same approach as with the Absolute Stream).
Future-proof re-clocking / phase correction
For jitter elimination, a specially designed re-clocking circuit, comprising of a femto clock architecture, embedded in eos Stream as standard and not as an option with extra charge. This is an upgradable platform for any future technology advancements.

Independent power lines, special power for the rendering CPU
The eos Stream circuit features separate, discrete power lines with low-noise linear power supplies that deliver the necessary voltage levels.
Emphasis in noise elimination
Prioritizing sound quality above all, we minimized internal components that generate noise. This streamlined and straightforward design of the eos Stream delivers exceptional audio performance, precisely meeting the expectations of discerning music enthusiasts.
