The PM-15S2 uses the latest generation of Marantz-own HDAM modules, as well as a top-down version of the PM-11S2s Constant Current Feedback MM/MC phono stage, which vinyl fans will simply fall in love with. The powerful Toroidal transformer delivers exceptionally high current values to instantaneously follow every dynamic and every detail of the music, while an additional CD direct input buffer ensures a completely unadulterated audio signal. In addition, the symmetrical circuit architecture, with system block shielding and independent left and right heat sinks, eliminates cross-channel interference for the clearest, most visible of sound stages. One of the units many convenience innovations is the special Power Amp Direct Mode, enabling you to use the PM-15S2 as a pure power amplifier – useful when combining a high-quality AV System with an audiophile stereo set-up. Also, with rigid double layer chassis, aluminium front and side panels, and an additional bottom plate to minimise external noise, the PM-15S2 is as solid as it gets. It all adds up to an extraordinarily high-quality stereo sound.
