Description

Nu Prime STA-9X : Stereo Power Amplifier

The NuPrime STA-9X, a 2 X 130W Class A+D stereo amp, bridgeable into a 330W mono amp, is designed with enhanced even-order harmonic circuitry that mimics the most attractive features of tubed and Class-A amp sound without incurring their drawbacks and limitations. The STA-9X’s frequency response to 50 kHz elevates vocals into emotional experiences; similarly, instrumental upper registers mimic a live performance’s shimmering heights.

Specifications :

Completing the ensemble is NuPrime’s new linear power supply with its high-efficiency toroidal transformer for reduced high-frequency noise and strengthened low-frequency performance. The damping effect of the NuPrime proprietary isolation feet absorbs and cancels vibrations that degrade audio performance. The overall result is unprecedented transient speed and an almost shocking level of dynamic impact.
In summary, NuPrime STA-9X has a sound characteristic that is spacious, transparent, dynamic, luxuriously textured with extended high-frequency.

 

Features:

  • Improved over STA-9, the STA-9X Single End Non-Negative Feedback Class A and Dual Feedback Class D amplifier design derives from AMG STA. This design allows STA-9X to produce more details and higher resolution than STA-9.
  • Stereo mode bridgeable into mono mode.
  • Enhanced even-order harmonic (H2) circuitry creates warmth and natural sound characteristic.
  • Highly reliable under no-load condition and enhanced short circuit protection.
  • 130% higher output current drive capability than STA-9 allows low impedance speakers to have better dynamic and power.
  • Operating at 750 kHz switching frequency, it produces high resolution with extended frequency.
  • A new linear power supply with a high-efficiency toroidal transformer reduces high-frequency noise and strengthened low-frequency performance.
  • The signal path avoids cross-linking capacitors, thus achieving a frequency response at the DC level for pure musical enjoyment.

The NuPrime Sound

  • Vast soundstage
  • Wide, lightning-fast dynamics
  • Ultra-low distortion and noise
  • Music emerges from a pristine background, with delicate details and nuances intact
