Join the revolution
We at HEM, Polish audio electronics designer and manufacturer and home of Ferrum, proudly introduce ERCO, a headphone DAC/AMP that could be the centre of any personal audio system.
We began our quest for honest sounding hifi gear at the foundation of every hifi chain. We set out to create a
power supply that would disrupt the audio community. HYPSOS proved to be a great success, which was widely
recognised by getting the coveted EISA award for best hifi accessory for 2021-2022, bestowed upon us by the
leading hifi journalists from all over the world. We then set out to broaden our horizon.
Our second Ferrum product in line was the stunningly understated Ferrum headphone amplifier called OOR. You can imagine our excitement when we received another EISA award, but now for our OOR.
