M Nu Prime ST-10 : Mono Power Amplifier

The NuPrime ST-10M Reference Class Mono Power Amplifier builds upon NuPrime’s fourth generation (V4) amplifier module from the ST-10 stereo power amplifier and brings it to the next level. The ST-10 stereo power amplifier was designed within the space limitation of its chassis and hence had a power system which was capable of providing 150W power output to each of the stereo channels. To really bring out the best of the V4 amplifier module, the ST-10M mono power amplifier has a new 300W power supply for its mono channel. The entire design including the chassis has been optimized for the mono configuration, further lowering the cross channel interference.

The NuPrime Sound

The ST-10M sounds more full bodied and rich, conveys greater immediacy and power as compared to the ST-10. The improved power delivery and reduced interference gives the instruments richer overtones and more natural decay. The soundstage is deeper and creates a greater sense of space. Imaging gains more solidity over the ST-10 which already has an impressive placement.

The sonic differences between the ST-10 and the ST-10M can be heard on the following examples. The striking of piano keys demonstrates greater attack and faster transients, with a sound that naturally resonates with the piano body. Brass instruments sounds glorious, characterful and carries a natural sheen but not overly bright. Female vocals and high frequencies retains the signature of the ST-10 but is smoother on the ST-10M. In an ensemble, the tonality gains an extra notch of richness which makes the overall presentation more natural.

4th Generation Amplifier Module Highlights:

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.
