To achieve such high quality, while still delivering class-leading power, means optimizing each section of the amplifier for its task, just as would be done in a design using a separate preamplifier and monoblock power amps.
Fully Balanced, From Input to Final Power Section
By keeping the signal balanced all the way through the amplifier, and combining that with optimized power supply design, the Marantz engineers were able to achieve maximum noise rejection throughout the audio path, and the highest possible signal purity.
An important part of noise-reduction is the fact that the PM-10 is a purely analog amplifier: Marantz keeps things as clean and simple as possible with its highly-developed all-analog design.
Balanced, Bridged Power Amplification
For the PM-10, Marantz wanted the purest possible sound, plus the power and dynamics to drive and control some of the world's most demanding speakers. To achieve this, Marantz continued the balanced working found in the preamp stage right through to the power amplifier stage to its speaker outputs and adopted bridged working to develop the power required while maintaining that balanced design. This True Balanced Concept realizes a ground-free signal management from the input to the output.
Carefully Selected Components
Marantz has long built a reputation for choosing the best-possible components for its reference series products - and if we can’t find what we want, we design and build the required part.
Built to Perform
Like the partnering SA-10 Super Audio CD/CD player/DAC, the PM-10 is constructed to the highest possible standards, with a double-layered copper-plated chassis for excellent rejection of mechanical and electrical interference, and casework constructed from thick, heavy, non-magnetic aluminum panels. Both products also sit on aluminum machining feet to reduce vibration for you to enjoy your music uninterrupted.
