The PM-11S1 fulfills the promise of no-compromise sound with the finest wideband sources as it preserves the simple yet elegant designs unique to Marantz for more than half a century. The PM-11S1's circuitry draws directly from the SC-7S1 preamplifier and MA-9S1 monoblock power amplifier. A toroidal transformer forms the heart of a prodigious multi-segmented power supply. All inputs and outputs, including the MM/MC phono, are buffered with Marantz'a HDAM-SA modules to insure satin-smooth signal transfer. A precision volume control and WBT speaker terminals merely hint at further refinements. And you can synchronize multiple PM-11S1s for the finest multi-channel music systems.
