Offered is „OOR“ by Ferrum Audio as second-hand device from the category „Headphone Amplifier“ on audio-markt.de - the online market place for high-end. The advert with the number 2695296185 ends on 28.11.2026 at 14:06 o'clock.
At €1,500, this sits right on the used-market median and just under current new pricing of about €1,995, so it reads as fair rather than a steal. It is comfortably below the 75th percentile at €2,162, which keeps it in sensible territory for a clean example.
That makes sense for a well-regarded amp: the OOR is known for serious drive, low noise, and a very resolved, fast presentation, with enough power for demanding planars and plenty of refinement for easier headphones. If the unit is clean and includes the original supply and box, it’s a solid buy; there’s no need to overcomplicate it at this price.

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.
