NuPrime Evolution STA-SE

The hybrid design aims to give you the best of both worlds: the warmth and natural texture typically associated with Class A amplification, paired with the efficiency, speed, and power delivery of Class D. It results in a sound that is both highly detailed and musically engaging without the harshness sometimes found in pure digital designs.

An ultra-high 1M Ohm input impedance reduces the load on your preamplifier, allowing it to pass the signal through with much less stress. This helps preserve the integrity of the audio signal, resulting in a more transparent, open, and realistic soundstage.

The Evolution STA-SE is designed as a mono power amplifier, meaning it provides 300 watts of power to a single channel. To create a stereo system, you will need to purchase two units—one for the left channel and one for the right.

The 700kHz switching frequency is significantly faster than standard Class D amplifiers. This high speed allows the amplifier to react more precisely to complex musical transients, resulting in tighter bass control and a more accurate, lifelike reproduction of high-frequency details.

While the 15mm hardened aluminum chassis is aesthetically striking, its primary purpose is structural and functional. It provides a rigid, vibration-resistant housing that protects the sensitive internal components from mechanical interference, which helps maintain signal purity.

With 300 watts of power in a mono configuration, this amplifier is capable of driving a wide range of demanding, low-sensitivity speakers with ease. It is particularly well-suited for high-fidelity systems where you want to maintain absolute control over the speaker drivers without sacrificing tonal richness.
