NuPrime ST-10
NuPrime ST-10 power amplifier, designed by Jason Lim, which aims for a sound rendering close to that of a valve amplifier thanks to its carefully designed linear power supply.
Description
The NuPrime ST-10 is a power amplifier designed by Jason Lim, presented as the continuation of the V3 models originally developed under the Nuforce brand. It belongs to a line of amplifiers designed to deliver a rich sound while relying on modern electronic architecture.
Its design is based on a linear power supply paired with a high-efficiency toroidal transformer. This choice aims to limit noise and distortion at high frequencies, while providing greater control and firmness in the reproduction of low frequencies. The signal path has also been shortened, with the aim of limiting the number of components the signal passes through and preserving the purity of the audio signal.
The result sought by the manufacturer is a sound that comes close to that of a good valve amplifier, without the constraints usually associated with that technology, such as maintenance or the ageing of the valves.
This type of amplifier is aimed at hi-fi enthusiasts looking for power electronics capable of adding body and warmth to their system, without going as far as a classic valve amplifier. It will particularly suit those who wish to pair a source and a preamplifier with a power stage that is neutral in appearance, yet carefully designed in its reproduction of bass and treble.
What to check before buying used
Check the operation of the volume potentiometer, whose resistive tracks may crackle or cause a channel imbalance after several years of use. The capacitors in the linear power supply also deserve particular attention, as their capacitance degrades over time and can affect low-frequency control. A check of the toroidal transformer (no humming or abnormal heating) and of the input/output connectors completes the points to examine before purchase.
