The Marantz SA-14, and the flagship Marantz SA-1 (which was the first Super Audio CD/CD player produced by Marantz) all utilize a Japanese made Sharp engine. This engine combines an aluminium die-cast disc tray and zinc die-cast mechanism base. The different metals helps to counter resonance. Future high-end machines will also likely feature in-house engines.

The first Marantz multi-channel Super Audio CD/CD player, the Marantz SA-12S1, is unique since it is based on the first Philips Super Audio CD player, the Philips SACD1000 (not sold in Japan), has been carefully designed to meet the requirements of audiophile, and uses a Philips Super Audio CD/DVD video/CD engine.
