Extensive and painstaking tuning has long been the secret of fine sounding Marantz amplifiers. For the PM-12SE, the Marantz engineering team used all their experience and expertise, both in the design of the amplifier and in the long listening sessions involved in finalizing the sound. The team of Sound Masters located in Japan and Europe didn’t stop their intensive work until they were absolutely certain they reached the height of quality worthy of the Marantz name.
Marantz developed its own discrete circuit boards called Hyper-Dynamic Amplifier Modules, or HDAMs, to replace the chip-based amps used elsewhere. Using discrete surface mount components with short mirror-image left and right signal paths, HDAMs outperform the regular integrated Op-amps dramatically in Slew Rate and noise level. The result is much more dynamic, accurate and detailed sound. Over the years, Marantz has developed different HDAMs to fit the particular requirements of players and amplifiers. The PM-12SE uses the latest high-grade SA3 version. Combined with optimized circuit design layout and carefully selected components, the PM-12SE provides exceptional sound quality and performance.
Current Feedback amplification is a well-known, Marantz-original circuit technology, thoughtfully designed to match the requirements of Super Audio hi-res music for wide-bandwidth, high-speed reproduction. The impedance at the Current Feedback point is limited, generating a very low phase shift. Marantz Current Feedback amplifiers reduce the need for phase compensation by minimizing Negative Feedback (NFB). This simplifies the signal path and results in a high through-rate, excellent transient response and superb sonic transparency across the full bandwidth. Unlike conventional Voltage Feedback topology, Current Feedback also makes the power amplifier insensitive to difficult loudspeaker loads.
Drawing on design elements of the PM-10, the PM-12SE is built to leverage enhancements, maintain the purest possible sound and support the power needed to drive the most demanding speakers. The amplifier output stage of the PM-12SE allows a large power output, delivering 2x100W into an 8ohm load, and easily copes with high-impedance speakers thanks to a 2x200W output into 4ohms. The amplifier module connects directly to the rear panel PCB on the PM-12SE to maintain signal purity and sound stability.
The purely analog design of the PM-12SE contributes to its noise-reduction structure and clean build: many rival designs are today including digital-to-analogue conversion, or adopting digital amplification and volume control, but Marantz keeps things as clean and simple as possible with its acclaimed all-analogue design. It may seem convenient to have a DAC in the amplifier, but digital circuitry is by its very nature, noisy (in the electrical sense) and can interfere with the delicate analogue signals passing through the amp. That's why Marantz chose to design its Premium Series range without any digital-to-analogue conversion, keeping its amplifiers as pure and clean as possible.
There’s also a Power Amp input, taking the signal straight from the input section to the power stage to let the unit work as a pure power amplifier.
