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.
