Product description
With the Nuprime AMG STA-SE, you can experience sound in its purest form—a monoblock amplifier that takes audio reproduction to new heights. This technical masterpiece combines innovative design with exceptional performance to deliver an extraordinary listening experience.

Demo unit of the NuPrime AMG STA-SE in excellent condition!
Sold with a 1-year warranty.
  • Stereo: 2 x 130W @ 8 Ohms, 2 x 200W @ 4 Ohms
  • Mono: 300W @ 8 Ohms, 320W @ 4 Ohms

 

Revolutionary technology meets aesthetic elegance
The AMG STA-SE is not just an amplifier—it is a work of art. The eye-catching front panel, made from 15 mm hardened aluminum alloy, undergoes meticulous 48-step milling with a diamond cutter. The three-dimensional “floating” logo and diamond-cut edge are just some of the details that make the AMG STA-SE a visual experience.

Improvements in the SE special edition (AMG STA-SE vs AMG STA)

  1. The improved Class D circuit reduces MOSFET temperature by 30% during high-speed operation above 750KHZ (more precise PWM waveform), improving energy efficiency and ensuring sound stability. In terms of sound performance, this results in a more relaxed and natural presentation.
  2. By using ultra-high-precision resistors with a minimum tolerance of 1/1000, the system exhibits extremely low drift, with a temperature coefficient of only 15 parts per million. In general, it is unusual for amplifiers in this price range to use components with such high precision. This ensures that negative-feedback sampling is not affected by external temperature variations and environmental factors, improving the precision and level of detail in music reproduction. The result is a clearer presentation of musical details.
  3. A newly developed and fine-tuned secondary negative-feedback circuit improves detail and precision in the soundstage, delivering sharper sonic contours and improved spatial positioning.
  4. By utilizing a high-capacity power-supply capacitor and low-impedance routing for the primary power path, the system improves dynamics and energy in the sound. Instantaneous supply current increases to 1.5 times that of the original AMG STA design.
  5. With a fundamental Class D oscillation frequency of between 700 and 750 kHz, the system achieves excellent high-frequency bandwidth and sound resolution.

Unmatched sound quality
  • Powerful performance: With an impressive output of 300W, the AMG STA-SE delivers incredible dynamics and energy in music reproduction
  • Innovative circuit design: A unique combination of a Single-Ended Non-Negative Class A module and a Double Feedback Class D module results in an exceptionally smooth and natural sonic character
  • Advanced Class D technology: With a switching frequency above 700 kHz, the AMG STA-SE achieves outstanding high-frequency reproduction and sound resolution

Technical highlights
  • 1M Ohm input impedance for optimal source compatibility
  • Aerospace-grade precision resistors with a minimum tolerance of 1/1000
  • Newly developed secondary negative feedback for improved channel separation and image precision
  • High current capacity for improved dynamics and energy
  • Innovative power supply for minimal external interference and ultra-low noise

Listening experience
The AMG STA-SE offers an extraordinary listening experience. It delivers a full and rich tonal character that gives instruments and voices extra body, weight, and harmonic richness. The soundstage is wide and deep, with a kind of spotlight effect that highlights performers in a captivating way.
Whether you listen to jazz, classical, or vocal music, the AMG STA-SE will give you a transparent, engaging, and realistic soundstage that takes you straight to the heart of the music.

Flexibility for demanding systems
With the ability to switch between stereo and mono operation, the AMG STA-SE offers welcome flexibility. It can be adapted to different speaker systems and room configurations, making it ideal both for stereo setups and for those who want to build a multichannel system with multiple monoblocks.

For the discerning audiophile
Nuprime AMG STA-SE is created for those who demand the very best in audio reproduction. It represents the culmination of Nuprime’s engineering expertise and passion for perfect sound. With the AMG STA-SE in your system, you will discover new dimensions in your music collection—details, nuances, and emotions you have never experienced before.
