NuPrime - EVOSTA - 230W Evolution STA Stereo Power Amplifier
NuPrime - EVOSTA - 230W Evolution STA Stereo Power Amplifier
Purpose-built for ultra-high-resolution systems that demand both brute strength and surgical finesse, the NuPrime EVOSTA 230W Evolution STA Stereo Power Amplifier delivers commanding output with stunning dynamic agility. Designed as part of NuPrime’s flagship Evolution Series, this amplifier is ideal for driving full-range loudspeakers in reference-grade stereo setups or paired in mono for ultra-high-current configurations. With its wide bandwidth, ultra-low distortion, and black-silent background, the Evolution STA offers the sonic grip and refinement required by serious listeners who value both microdetail and macrodynamic scale.
The EVOSTA leverages NuPrime’s proprietary Class A+ architecture, which combines a linear Class A input stage with a high-speed switching output stage. This unique topology provides Class A sweetness and warmth with the efficiency and power of Class D, resulting in fast transient response, rich harmonics, and exceptional control over complex speaker loads. The amplifier features fully balanced circuitry, RCA and XLR inputs, high-quality gold-plated binding posts, and advanced feedback design that actively suppresses harmonic distortion and phase shifts.
For audiophiles seeking a powerhouse amplifier that never sacrifices nuance, the NuPrime Evolution STA delivers reference-level performance in a compact, elegantly machined chassis. It’s the perfect foundation for systems that reveal the soul of a recording while maintaining absolute authority over the loudspeakers.
