The company had a major influence in the development of high fidelity audio systems, and reached the high point of their success in the mid to late 1970s. During the 1980s, while owned by Philips, a pioneer in compact disc technology, Marantz built some very well received CD players, but other products in the line were not as successful as in the past. As of the early 1990s, Marantz has focused on higher-end components.
