Description

Class A+D Stereo Amp bridgeable into a 290W mono amp

The NuPrime STA-9, a 2 X 120W Class A+D stereo amp, bridgeable into a 290W mono amp, is designed with enhanced even-order harmonic circuitry that mimics the most attractive features of tubed-amp sound without incurring tubes’ drawbacks and limitations. The STA-9's spacious, transparent, dynamic and luxuriously textured soundstage has to be heard to believe.

Features

  • Single End Class A + D amplifier design
  • Bridgeable allowing switch between stereo or mono mode.
  • Enhanced even-order harmonic (H2) circuitry resembling the most attractive features of tubed-amp sound without its drawbacks and limitations.  
  • Highly reliable under no-load condition and enhanced short circuit protection.
  • High output current drive capability for low impedance speakers.
  • 550 KHz switching frequency for accurate reproduction of musical signal.
  • New linear power supply with a high-efficiency toroidal transformer.  Reduced high-frequency noise and strengthened low-frequency performance.
  • Signal path avoids cross-linking capacitors, thus achieving a frequency response at 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

In summary, NuPrime’s sonic character stands well apart from – and indeed above – the soft, cushy sound we often associate with most tubed amplification or the dry, clinically edgy sound we often associate with solid-state and switching technology. Rarely does an amp achieve an ideal balance of richly textured timbres and harmonics, bottom-end authority, startling dynamics, exquisite low-level detail, and a fully revealed, fully dimensional soundstage against a backdrop of mile-deep silence.
