Description

Reference LE class power amplifier

The ST-10 amplifier is NuPrime's Reference LE (near-reference) power amplifier for listeners who require a reference-class amplifier at a somewhat lesser power rating of 2 x 150W (8 Ohm). NuPrime’s sonic character stands well apart from – and indeed above – the soft, cushy sound we often associate with most tubed amplification and 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 sound stage against a backdrop of mile-deep silence.

The “LE” of Reference LE designates near-reference-class performance.  The fourth generation (V4 amplifier module) of this patented amplifier design outperforms its predecessor in several aspects:

  • It lowers the noise floor by an astounding 20dB and elevates the output stage to 85% efficiency.
  • Shortened circuit pathways result in a 20% improvement in through-put.
  • Improved reliability in no-load condition and short circuit protection.
  • Increased output current drive capability for low impedance speakers.
  • Increased switching frequency to 600 KHz and an improved musical sampling rate.
  • Improved S/N ratio and dynamic range.
  • 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.
  • Enhanced even-order harmonic (H2) circuitry resembling the most attractive features of tubed-amp sound without its drawbacks and limitations. 
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
