Problem solved :-)

Please allow 10 business days for product handling and upgrading. Thank you!

NuPrime ST-10:

Reference class power amplifier

The ST-10 amplifier is 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 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

ST-10 is a phase inverting amp. If you are certain that the +/- (usually the red/white connectors) phase of your inputs are non inverting, then you should reverse the +/- inputs for each channel on ST-10.  All other NuPrime amps were designed as non-inverting amp.  If you have no idea what this is all about, don’t bother with making any adjustment.
