In addition to HDAM technology, the SR5012 also features Current Feedback instead of the typical voltage feedback configuration. A Marantz innovation introduced on our very first audiophile amplifiers more than 60 years ago, Current Feedback technology provides a wide closed-loop bandwidth and very high slew rate, delivering superior fidelity with wideband audio sources.
