The specified performance figures are impressive: 500 W into 8 ohms, doubling to 1,000 W into 4 ohms and 2,000 W into 2 ohms. This places the Momentum Z among the most powerful home audio amplifiers, but sheer power is only part of the story. The main focus lies in how that power is controlled. The Kinetic Drive Regulator uses a hybrid of MOSFET and bipolar transistors to stabilise the amplifier against fluctuations in the mains supply and varying speaker loads, reducing noise, lowering distortion, and ensuring more consistent control of demanding loudspeakers.
