Ferrum Audio OOR + WANDLA + HYPSOS Dual inc. DC POWER LINK Cables

Ferrum OOR Headphone Amp With WANDLA DAC & HYPSOS Dual Output Power Supply

Overview

The Ferrum Audio High-End System brings together four reference components designed to perform as one. Combining the WANDLA DAC, OOR Balanced Headphone Amplifier, HYPSOS Dual Output Hybrid Power Supply, and two Power Link (FPL) Cables, this setup delivers an uncompromising blend of precision, dynamics, and musical emotion.

Built in Poland, each component reflects Ferrum Audio’s vision — engineering innovation dedicated to reproducing sound as naturally and faithfully as possible. Together, they form a fully balanced, high-end headphone and preamplifier system capable of breathtaking realism.

At the core lies the Ferrum Audio WANDLA DAC, winner of EISA Best DAC of the Year 2023-2024. Known as “The Converter”, WANDLA redefines digital-to-analogue performance with cutting-edge precision. It uses a proprietary ARM-based processing platform and an ESS Sabre converter stage to deliver remarkable tonal accuracy, texture, and clarity. WANDLA supports PCM up to 768 kHz, DSD512, and full MQA decoding, ensuring compatibility with the highest-resolution sources.

From the DAC, the signal flows to the Ferrum Audio OOR, a fully balanced headphone amplifier and preamplifier designed for natural musical expression. OOR preserves micro-detail and timing with exceptional transparency and speed. Its analogue circuitry provides a silent background, clean gain structure, and effortless control across a wide range of headphones. When used as a preamp, it integrates seamlessly with powered speakers or external amplifiers for a cohesive system experience.

Powering both units is the Ferrum Audio HYPSOS Dual Output Hybrid Power Supply, designed to energise two components simultaneously with absolute precision. Combining linear and switch-mode technologies, HYPSOS delivers ultra-stable, low-noise power over a 5 V – 30 V DC range. Its hybrid topology ensures low ripple, fast transient response, and tonal balance — all vital for reference listening.

The HYPSOS Dual Output version features two independent outputs that share a total current capacity of 6 A. Its intelligent power management maintains perfect stability for both the OOR and WANDLA, even during dynamic musical passages. The 4-Terminal Sensing Design (4TSD) guarantees the exact voltage reaches each device, while Sweet Spot Tuning (SST) lets users fine-tune voltage for optimal sonic synergy.

Connecting each component are two Ferrum Power Link (FPL) Cables, purpose-built for this system. Using 4-pin Weipu DC connectors, the FPL features dedicated conductors for both power and feedback. This design eliminates voltage loss and interference, ensuring each component receives pure, consistent energy directly from HYPSOS.

Visually and functionally, the system is unified through Ferrum’s signature minimalist design. Each chassis features precision-milled aluminium construction, compact dimensions, and clean lines for effortless integration. Whether used on a desktop or in a dedicated listening space, the system’s aesthetic matches its technical perfection.

Together, the WANDLA DAC, OOR Amplifier, HYPSOS Dual Output, and FPL Cables create a system of remarkable coherence and balance. The DAC provides the insight and refinement, the amplifier adds natural power and dynamics, and the power supply ensures stability and precision. The result is sound that is open, fluid, and emotionally captivating — the purest expression of Ferrum Audio engineering.

For Groove Central listeners who demand the highest level of headphone performance, the Ferrum Audio High-End System represents the pinnacle of Ferrum design. It’s an integrated solution built for precision, passion, and the pursuit of perfect sound.
