Grimm Audio

Grimm Audio started in a Dutch recording studio called Fairytapes, where sound engineer Eelco Grimm spent years working with equipment designed and built by analog specialist Guido Tent and technical editor Peter van Willenswaard. The three had been talking about building a reference-grade AD converter when they met Bruno Putzeys at an AES convention in Amsterdam in 2003. Bruno had just presented a novel ADC topology that solved problems nobody else was addressing. Instead of licensing the design, they brought him in as a partner and founded Grimm Audio in 2004.

What makes Grimm different from every other high-end audio company is that dual perspective. Eelco comes from pro audio (he still lectures at the University of the Arts Utrecht and contributed to the EBU R128 broadcast loudness standard). Guido and Peter came from the HiFi world. The result is a company that designs with studio-grade measurement rigor but listens with an audiophile's obsession for musical engagement. Their research into clock jitter revealed that the emotional impact of music is far more sensitive to timing instability than anyone in the industry had assumed. That insight shaped everything they build. Every Grimm product is designed and built in the Netherlands.
