NuPrime Evolution Two Mono Power Amplifier The NuPrime Evolution Two offers a proprietary Only Distortion Cancellation (ODC) design, advancing the state-of-the-art Class-D for the past decade. This design derives the error signal from MOSFET devices and the output filter circuit directly, significantly reducing the negative feedback signal, which resulted in a substantial reduction in distortion. With a massive RMS power of 600W @4Ohm and yet achieving ultra-low distortion of THD+N of 0.003% @1kHz(5W), 0.006@1kHz(100W) and less than 0.006% THD+N at 1KHZ(2W~100W), it is a stunning achievement by itself. This breakthrough improvement in Class-D design resulted in a natural and pure sound characteristic. Features NuPrime breakthrough Only Distortion Cancellation (ODC) Class D design. Preamp stage and Class D oscillation circuit utilizing high-end NJR MUSES8820 op-amp. 650KHz high-speed switching frequency allows greater resolution to be achieved. The 900W(Peak power) high-power ultra-thin toroidal transformer power supply has been enhanced to deliver cleaner and more stable power with a lower noise floor. The entire power path fully adopts 40A ultra-high current and low resistance terminals. Improve current dynamic capability. Total of 48400uF (one channel ) power supply filter capacitors. High quality copper PCB trace instead of usual cables are used to connect the power supply to the amplifier’s circuitry, maximizing power delivery. Hybrid Class-D technology that retains the merits of both Class-A and Class-D amplification. A mono implementation.
