Meticulous engineering and high-quality construction are the hallmarks of Marantz receivers. The SR4023 starts with a front panel made of fiberglass-reinforced aluminum. This advanced composite material helps shield internal circuitry from performance-robbing interference and vibration. Inside, this receiver’s oversized power supply and fully-discrete amplifier design pack plenty of high-current power to deliver the excitement and dynamics of your favorite tunes.
