The Ferrum HYPSOS is the first product from Ferrum, drawing on more than two decades of HEM expertise in audio electronics. This hybrid DC power supply is designed to replace ordinary wall-warts and generic supplies with a quieter, more stable and more musically revealing source of power. This pre-owned unit is in good condition in black. No accessories or original packaging are included.
By combining the low-noise character of a linear supply with the speed and efficiency of a switching design, the HYPSOS lets existing digital and analogue components perform closer to their potential—often with a more detailed yet unfatiguing presentation.
Visit our Lane Cove showroom to hear what a dedicated hybrid supply like the HYPSOS can bring to a quality audio system.
Why Choose the Ferrum HYPSOS Power Supply?
The HYPSOS is a versatile, software-controlled hybrid PSU built to extract more performance from a wide range of DC-powered audio components.
• Lower Noise Floor: Hybrid architecture reduces ripple and hash compared with typical switching supplies.
• On-the-Fly Voltage Adjustment: SST makes it easy to find the most musical operating point for each device.
• High Current Delivery: Up to 6 A continuous and 9 A impulse current for demanding loads.
• Universal Compatibility: Works with quality components using standard DC connectors across 5–30 V.
• Software Controllability: Presets, automation and firmware updates keep the unit current.
Discover the Ferrum HYPSOS at our Lane Cove showroom to experience the difference a properly engineered hybrid supply can make.
At the heart of the HYPSOS is a hybrid power system that merges the best traits of linear and switching designs. The result is low residual noise, rapid transient response and enough current to support a wide range of streamers, DACs, phono stages and similar components.
Four-terminal sensing and Spread Spectrum Mode further refine the delivered power.
Because voltage can be adjusted in fine steps, the Ferrum HYPSOS becomes a genuine tuning tool rather than a simple replacement PSU. Many listeners report greater clarity, tighter bass and a more relaxed long-term presentation once their components are fed from this supply.

Compared with the obvious new-cable-or-basic-accessory money at this level, A$1,500 for a used Ferrum Audio HYPSOS lands just under the A$1,589 median and a touch above the A$1,487 25th percentile, so it reads as fair-to-very-good value rather than a steal. It is not cheap enough to call a bargain, but it is priced sensibly for a sought-after power supply in the current AUD used market.
HYPSOS has a strong reputation for lowering noise, tightening bass, and giving compatible gear a more composed, dimensional presentation, so the appeal is real if it fits your setup. At this price, the upside is in getting a genuinely well-regarded upgrade piece without paying top-of-market money; if the unit is complete, clean, and has the right cable/voltage setup for your gear, it looks like a sensible buy.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
Ferrum Audio emerged from Poland's Warsaw region as a fresh entrant in the audiophile world, launched by parent company HEM under CEO Marcin Hamerla. Drawing inspiration from local ironworking heritage—where "Ferrum" means iron in Latin and nods to the area's metallurgic past and Hamerla's blacksmith father—the brand embodies Polish craftsmanship fused with high-end audio design. Locally engineered and manufactured, it represents years of accumulated expertise without a specific founding year disclosed, quickly gaining traction since its debut products.
The lineup centers on compact, high-performance desktop and head-fi electronics, spotlighting the HYPSOS power supply as its firstborn, followed by the OOR headphone amplifier, ERCO DAC/amp, and WANDLA DAC. These siblings excel standalone but pair synergistically, especially with HYPSOS, delivering exceptional musicality. Ferrum avoids speakers, turntables, or cables, focusing instead on DACs, amplifiers, and power solutions tailored for headphones and living-room setups.
Positioned as a niche boutique force in the high-end market, Ferrum has surprised the head-fi scene with its iron-clad builds, precise sonics, and value, conquering global dealers from its Polish roots. For discerning buyers seeking uncolored, dynamic audio without excess bulk, it stands as a confident, modern contender.
