NuPrime Evolution STA Stereo Amplifier

The ODC design is a proprietary circuit that actively identifies and subtracts distortion from the signal path. This results in a significantly cleaner background and improved clarity, allowing you to hear more detail in your music without the harshness often associated with high-power amplifiers.

While traditional Class D amps focus primarily on efficiency, the Evolution STA uses a hybrid approach to bridge the gap between Class A and Class D. It provides the high-speed, high-efficiency power delivery of Class D while incorporating circuit refinements that produce the natural, warm tonal characteristics typically found in Class A designs.

Yes, the Evolution STA is equipped with both balanced XLR and unbalanced RCA inputs. It uses high-quality Furutech connectors for both, ensuring a secure and reliable connection regardless of which input type your preamplifier or source component uses.

With 310W per channel at 4 Ohms and a robust 550W toroidal transformer, the Evolution STA is designed to handle difficult speaker loads with ease. Its high-current delivery and large 52,000uF capacitor bank ensure it maintains stable performance even when speakers demand sudden bursts of power.

The dual mono design uses separate power and amplification paths for the left and right channels. This physical and electrical separation minimizes crosstalk, resulting in a wider, deeper soundstage and more precise imaging.

While the amplifier is efficient, it will perform at its best after a short period of operation once the internal components reach a stable thermal state. Because of its hybrid design, it reaches this state relatively quickly compared to pure Class A amplifiers.
