EISA HEADPHONE AMPLIFIER 2022-2023
Following the EISA Award-winning Hypsos programmable power supply unit, Ferrum has focused its expertise on designing a purely analogue headphone amplifier. The OOR (Dutch for ‘ear’) offers a deep and wide response, and enough power to drive even the most challenging of high-end headphones – whatever model you use, balanced or unbalanced, appears to have been given a shot of extra power. This superior performance is complemented by a compact, desktop-friendly design that emphasises ease of use, and is a cosmetic match for Ferrum’s Hypsos PSU, which can of course be employed by way of upgrade. Balanced and single-ended inputs and headphone outs cater to every listening scenario.
