NuPrime Evolution Two Stereo Power Amplifier

Description

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
