The PMA-720AE is equipped with an Advanced HC (High-Current) Single Push-Pull Circuit that enforces Denon’s design concept for pure audio amplification. This design ensures that you hear delicate musical details, reliably supported by plenty of power.
Playback faithful to the original sound is also made possible by a circuit board layout that can handle the greater power from the amplifier section and appropriately respond to the output level and unique character of the signal. In addition, the internal construction of the PMA-720AE has been carefully designed to prevent unwanted vibration from adversely affecting the audio signal.
