Nuprime ST-10

De Nuprime ST-10 versterker is een LE eindversterker voor luisteraars die een referentieklasse-versterker wensen met wat minder vermogen (2 x 150W bij 8 OHM). Vormt samen met de DAC 10H een zeer hoogstaand en stijlvol geheel met dito prestaties.

The NuPrime ST-10 amplifier is what NuPrime calls “near reference class.” Why only “near” reference? As far as reviewer SS can tell it’s because this stereo amplifier only puts out 150 watts per side into an eight-ohm load. The ST-10 is a very quiet, extremely low-noise power amplifier that, as long as it isn’t pushed into clipping, sounds exceedingly neutral and uncolored. The ST-10 did a superb job of driving a variety of speakers with authority and control.

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.
