Product Description

Manufacturer's Description:

Reference LE class power amplifier

The ST-10 amplifier is NuPrime's Reference LE 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.
