A best-selling flagship because it delivers world-class, multi-component performance within a single, elegant chassis. It is highly regarded by critics for its ability to drive almost any speaker with "effortless power" and "stunning transparency". It delivers 300W per channel into 8 ohms and 600W into 4 ohms, allowing it to control even the most demanding high-end speakers. According to Stereophile, it "shattered all notions of Class-D sounding colorless," instead offering remarkable warmth and a sense of "space and air".The amplifier is praised for its "superb bass control," delivering tight and well-defined low-end performance.
