The Marantz PM7200 is a high-quality, two-channel stereo integrated amplifier from the early 2000s, designed for music enthusiasts seeking audiophile sound quality and flexible operation. Its most notable feature is the ability to switch between Class A operation, which produces a warmer, smoother sound with minimal distortion at lower volumes (25 watts per channel), and the more efficient Class A/B mode, which delivers higher power (95 watts per channel at 8 ohms).
