Developing a successor for the widely appraised PM-17 series was not easy. Inspired by the already legendary SC-7/MA-9 combination and derived from the top class PM-11S1 we are proud to present the new Marantz PM-15S1. Coupling impressive design with outstanding performance we feel our engineers have created a worthy successor. The amplifier is built according to the new Marantz premium design without any visible screws, a heavy double layer chassis and a slightly blue illuminated front. The 3-stage construction with full Current Feedback and with short, symmetrical signal paths, independent leftand right heatsinks, and new HDAM-SA2?s ensure dynamic sound and perfect stereo imaging. Shortest signal path, best components, reduction of external noise and other will further extend the quality.Derived from the PM-11S1 we are using the electronic linear volume control WM8816 from Wolfson. The PM-15S1 reflects our engineers? passion for pure music, designed with the true audiophile in mind.
