Founded in 2020 as the HiFi subsidiary of HEM Electronics, Ferrum Audio emerged from over two decades of audio engineering expertise established by founder Marcin Hamerla near Warsaw, Poland. Named after the Latin word for iron, referencing the region's metallurgical heritage and its proximity to composer Frederic Chopin's birthplace Żelazowa Wola, Ferrum represents HEM's transition from being a respected OEM manufacturer to creating their own premium brand. Headquartered in Pruszków, Poland, the company leverages HEM's 20+ years of experience in digital technology and specialist audio electronics, having previously completed projects for the Polish government before focusing on industry-leading audio solutions. Under Marcin Hamerla's leadership as owner and CEO, Ferrum has achieved rapid recognition with multiple EISA awards including the 2021-2022 Best Hi-Fi Accessory for their HYPSOS hybrid power supply, 2022 Best Headphone Amplifier for the OOR quad-mono amplifier, and 2022-2023 Best DAC for the WANDLA digital-to-analog converter. The company's product lineup showcases innovative engineering including proprietary ARM-based platforms, custom digital filters developed with HQ Player, and unique hybrid power supply technology that combines switching and linear designs for superior performance in the high-end audio market.
