Clean Signal. Accurate Sound.
Ferrum Audio creates high-performance components built around one idea: clean, controlled, and accurate sound reproduction. From power delivery to digital conversion and headphone amplification, every product is designed to work with precision and consistency.
At Audio Art Cable, we carry a selection of Ferrum Audio products, including the Ferrum WANDLA DAC, Ferrum OOR amplifier, and Ferrum HYPSOS power system, each made to perform on its own or integrate smoothly into a complete system.
Ferrum Audio is a modern hi-fi brand from Warsaw, Poland, built on a foundation of engineering, craftsmanship, and precision metalwork. The name “Ferrum” comes from the Latin word for iron, reflecting both the region’s industrial heritage and a long tradition of working with materials at a high level of precision.
Every product is designed and assembled in Poland, combining modern audio engineering with traditional manufacturing values. The engineers behind Ferrum don’t treat audio as something abstract or overly complicated. They treat it as something physical, something you build, refine, and keep improving until it simply feels right when you listen.
Below is a selection of Ferrum’s key components, from standalone upgrades to complete system solutions built for DAC performance, amplification, and power delivery:

Ferrum Audio isn’t about adding complexity to your system. It’s about making each part of your setup work together more clearly and more reliably.
Ferrum combines modern DAC design, hybrid power systems, and headphone amplification into components that focus on precision and stability. The goal is simple: reduce noise and let your system perform without strain.
Ferrum products are designed to work together as a complete ecosystem. You can start with one component and expand over time, with each upgrade building on the last.
Every unit is designed and assembled in Poland by engineers who focus on consistency and long-term performance. Nothing is rushed, and nothing is left to chance.
Ferrum components are built to fit into real living and listening spaces. They deliver reference-level performance without demanding a large or complicated setup.
HYPSOS is Ferrum’s approach to solving one of the most important parts of any audio system: power. Instead of relying on a single method, it combines linear and switching technologies in a hybrid design that focuses on stability, low noise, and fast response.
By delivering more controlled and consistent power, it helps connected components perform with greater clarity and ease.
Dual output option. The HYPSOS Dual Output Hybrid Power System powers two devices at once.
Precision voltage control. Adjustable settings match the exact needs of your gear.
Improved signal integrity. Reduces noise and jitter when paired with DACs, preamps, or headphone amplifiers.
HYPSOS is often used as the foundation of a Ferrum setup, supporting other components with a more stable power base.
OOR is designed to give headphones a stronger, more controlled amplification stage. It builds on a clean power foundation and focuses on delivering accuracy, dynamics, and natural flow without unnecessary coloration.
Balanced circuitry. Maintains a clean signal path with minimal distortion.
High driving power. Easily handles high-impedance and planar magnetic headphones.
Transparent sound. Balances precision with an engaging, musical character.
When paired with HYPSOS, OOR benefits from an even more stable power supply, resulting in greater headroom and more effortless performance.
Just as OOR refines headphone playback, WANDLA refines digital conversion. It works as both a DAC and preamplifier. This makes it the centerpiece of a system. WANDLA brings advanced digital processing, a precision digital filter, and high-quality analog output for a natural, lifelike presentation.
High-performance DAC architecture for detailed, natural playback.
Functions as either a fixed-output DAC or a variable-output preamp.
Includes a headphone amplifier for an all-in-one digital solution.
When paired with HYPSOS, digital playback gains an even cleaner foundation.
Together, WANDLA and OOR cover the two key aspects of modern listening: digital accuracy and analog control.
Ferrum systems are built so each component supports the next. When paired together, they create a more complete and stable setup without the need for guesswork or complicated matching.
Each bundle brings together products that are already designed to complement one another, making it easier to build a system that feels balanced from the start.
WANDLA 2.0 & HYPSOS Bundle – A pairing that improves digital playback by supporting the DAC with a more stable and refined power foundation.
OOR & HYPSOS Bundle – A headphone-focused setup that delivers stronger control, improved dynamics, and a more effortless listening experience.
WANDLA, OOR & HYPSOS Bundle – A full system approach combining digital conversion, headphone amplification, and power optimisation for a complete Ferrum setup.
Even on their own, Ferrum products perform at a high level. Together, they feel more connected, consistent, and complete.

Ferrum Audio is a Polish company founded by engineers with decades of experience in professional and high-end audio. All products are designed and hand-assembled in Poland to ensure consistency and quality.
Ferrum is the Latin word for iron. It reflects both the brand’s industrial heritage in Poland and its focus on solid, precision-engineered audio components.
Ferrum Audio is often referred to simply as “Ferrum” in the hi-fi community. It is the same brand name used across all of their products.
Ferrum focuses on power delivery and precision engineering. Their HYPSOS hybrid power supply combines linear and switching technologies, while their DACs and headphone amplifiers are designed for transparency, control, and system synergy.
The HYPSOS power supply upgrade refers to using Ferrum’s hybrid power system to improve the performance of compatible components by delivering cleaner, more stable power with reduced noise and better control.
OOR and WANDLA will work on their own, but pairing them with HYPSOS improves stability, reduces noise, and enhances overall dynamics. Many users see it as a key performance upgrade.
The standard HYPSOS powers one device at a time, while the Dual Output version can power two components simultaneously. This is useful for systems that include both a DAC and amplifier or multiple compatible devices.
WANDLA 2.0 is a dedicated DAC and preamp. WANDLA HP adds a built-in headphone amplifier, making it a more complete all-in-one solution for both headphone and system playback.
Yes. OOR is a fully balanced headphone amplifier with enough power to drive everything from sensitive headphones to demanding planar magnetic models, while maintaining clarity and control.
Yes. While Ferrum products are designed for system synergy, they are fully compatible with other hi-fi brands. They can be integrated into a wide range of setups without issue.
Yes. Their compact design makes them ideal for desktop use, but their performance level also allows them to scale into full hi-fi systems as DACs, preamps, or headphone amplifiers.
Audio systems aren’t always straightforward. The right choice often depends less on specs and more on how everything comes together in your space.
If you’re at that point where you’re comparing options or still unsure what direction to take, a quick conversation with an expert can make things much clearer.
As an authorized dealer, we’ll walk you through it and help you make a clear, confident choice. Tell us what you’re working with and what you’re trying to improve, we’ll help you figure out what actually makes sense, without overcomplicating it.
