The NuPrime STA-100 is the most powerful (2x100W@8 Ohm & 2x150W@4 Ohm) entry-level high-end audio amplifier in its price range. It has a neutral and detailed sound characteristic.

STA-100 design incorporates high-speed gate driver error correction to achieve ultra-low distortion. Advanced protection circuitry safeguard STA-100 from failure due to fault conditions such as short circuits, overload, over-temperature, and under-voltage.

The Adaptive Voltage Switching Power Supply is the most innovative SMPS design introduced by NuPrime for the first time. The amplifier’s output signal feeds back into the power supply’s servo power stage, causing a change in the output voltages supplying the power stage of the amplifier. This design resulted in more details at a low music level and explosive power at a high volume.

Review: Totally Wired: “I’m struggling to find a downside. In fact the only one will be for us in that people may be so happy with the entry level to NuPrimes’ range that they choose not to look further up the food chain to the even better models; But more importantly this model is a welcome addition and delivers an authentic NuPrime experience to a whole new audience.“
