Introduction to dCS and Its Heritage

During my visit to the dCS factory in Cambridge, England, I had the privilege of interviewing the company’s original team. Nestled in the heart of the prestigious Cambridge University, this renowned location birthed a world-class institution and the pioneer in the high-end digital audio field, “Data Conversion Systems Ltd – dCS.” Since its inception in 1987, dCS has remained dedicated to analog-to-digital and digital-to-analog conversion. The company’s unwavering commitment to research and development, marked by numerous world-first achievements and patented technologies, has firmly established dCS as an industry leader.

Evolution and Expansion of dCS

From a modest team of ten at its inception, dCS has grown to a workforce of approximately fifty, with a strong emphasis on research and development. My visit to the dCS factory convinced me of the company’s exceptional talent pool and formidable research base.
