Heed Audio at a glance
Heed Audio is not just another hi-fi electronics manufacturer with British audio heritage in its DNA — it is a manifesto of authenticity, passion, and independent vision. Founded in Hungary, the brand stands out for its radically human approach to sound reproduction. In a market so often dominated by numbers, measurements, and technological catchphrases, Heed chooses a different path: that of the listening experience as an absolute value.
Every Heed product is designed to serve the music, not the machine. The amplifiers, DACs, and external power supplies are built according to a philosophy that places musicality, tonal coherence, and natural soundstaging at the very centre. There are no gimmicks — just tonal integrity and emotional balance that recall the finest British electronics of the golden era, reimagined with elegance, craftsmanship, and a modern spirit.
And that’s exactly where it all began — with one defining example:
In the 1980s, those who brought home an ION Obelisk experienced something rare and precious: the feeling of having discovered one of hi-fi’s best-kept secrets. It wasn’t a flashy amplifier, nor did it shout its specifications. But from the very first listen, many enthusiasts realised that something extraordinarily musical was happening.
Here’s what it felt like:
-
A sense of wonder: at how such a compact device could drive even demanding speakers with such ease and refinement.
-
Emotion: because the Obelisk didn’t impress through brute power, but through its ability to tell the story of music — with fluidity, dynamic range, and a sense of timing reminiscent of valve amplifiers.
-
Deep satisfaction: the kind that comes from extended listening sessions, free of fatigue, drawn into a sound that keeps you there.
-
A sense of uniqueness: because owning an Obelisk meant making a choice that went against the grain — a commitment to musical substance over passing trends.
In short, those who welcomed such a device into their home discovered an amplifier that didn’t try to dazzle with figures or appearance, but that won them over gradually, listen after listen, by speaking directly to the heart.
And on this front, Heed Audio makes no compromises. It doesn’t follow fashion. It’s not made for everyone. But those who discover it rarely look back. Because listening with Heed isn’t about technical showmanship — it’s about returning to music as a deep, living, and emotionally resonant experience.
If you’re seeking the soul of sound, Heed is a name worthy of your attention — and your respect.

The Ruark R-CD100 is distinguished by a design that combines aesthetics and functionality. Its structure is crafted from a combination of anodized aluminum and fused walnut, giving the device an elegant appearance and structural robustness. The precisely machined top and bottom plates not only add a touch of class but also contribute to acoustic isolation of the internal mechanism, minimizing external vibrations that could affect sound quality.
The compact dimensions of the CD player, with a height of 45 mm, width of 175 mm, and depth of 167 mm, make it easy to place in any home environment, blending harmoniously with other components of the 100 series. Its lightweight design, at 1.2 kg, further simplifies handling and placement.

This mechanism is compatible with a variety of disc formats, including CD-DA, CD-R, and CD-RW, offering notable flexibility for playing different types of media.
Integration with 100 series systems occurs via a USB Type-C connection, supporting USB 2.0 and 3.0 standards, ensuring stable and fast data transmission. Once connected, the player is automatically recognized by the system, appearing as an additional source on the main unit’s display. This plug-and-play approach simplifies installation and use, eliminating the need for complex configuration.
A key feature of the Ruark R-CD100 is the absence of an internal digital-to-analog converter (DAC). This design choice allows the player to take advantage of the advanced DACs present in 100 series devices, ensuring superior sound quality and tonal consistency across different sources. The result is detailed audio reproduction, with extended dynamic range and fidelity that satisfies even the most discerning listeners.
In terms of power, the player requires a 5V USB input with a maximum current of 1A, corresponding to a power consumption of 5W. This low energy requirement makes it efficient and easily powered via standard USB ports on compatible devices.
In summary, the Ruark R-CD100 provides an ideal solution for those who wish to integrate CD playback into their audio system without compromising sound quality, while benefiting from refined design and solid construction. Its compatibility with 100 series models and attention to build details make it a valuable component for any audiophile setup.
