Current Feedback
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.
Marantz HDAM Technology
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 PM8006 uses the high-grade SA3 version.

Marantz Musical Phono EQ
For a long time, Marantz integrated amplifiers have featured high-quality phono stages. We’ve elevated our commitment to vinyl with the Marantz Musical Phono EQ stage, as seen in the PM8006 amplifier. Marantz Musical Phono EQ uses two-stage amplification, allowing less gain per stage for lower distortion. The PM8006 combines Marantz HDAM technology with JFETs (junction gate field-effect transistors) in the input stage, providing high input impedance that eliminates the need for AC coupling capacitors and simplifies the signal path, vastly improving the signal purity overall.
