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.\u003c\/p\u003e\n\u003cp\u003eThe fourth generation (V4 amplifier module) of this patented amplifier design outperforms its predecessor in several aspects:\u003cbr\u003e\u003cbr\u003e– It lowers the noise floor by an astounding 20dB and elevates the output stage to 85% efficiency.\u003cbr\u003e– Shortened circuit pathways result in a 20% improvement in through-put.\u003cbr\u003e– Improved reliability in no-load condition and short circuit protection.\u003cbr\u003e– Increased output current drive capability for low impedance speakers.\u003cbr\u003e– Increased switching frequency to 600 KHz and an improved musical sampling rate.\u003cbr\u003e– Improved S\/N ratio and dynamic range.\u003cbr\u003e– New linear power supply with a high-efficiency toroidal transformer. Reduced high-frequency noise and strengthened low-frequency performance.\u003cbr\u003e– Signal path avoids cross-linking capacitors, thus achieving a frequency response at DC level for pure musical enjoyment.\u003cbr\u003e– Enhanced even-order harmonic (H2) circuitry resembling the most attractive features of tubed-amp sound without its drawbacks and limitations.\u003cbr\u003e\u003cbr\u003eThe NuPrime Sound\u003cbr\u003e\u003cbr\u003e– Vast soundstage\u003cbr\u003e– Wide, lightning-fast dynamics\u003cbr\u003e– Ultra-low distortion and noise\u003cbr\u003e– Music emerges from a pristine background, with delicate details and nuances intact\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli class=\"p1\"\u003eInputs:\n\u003cul\u003e\n\u003cli class=\"p1\"\u003eRCA: Un-Balanced input x 1\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eXLR: Balanced input x 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eOutputs:\n\u003cul\u003e\n\u003cli class=\"p1\"\u003eStereo Speaker Out x 1\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cul\u003e\n\u003cli class=\"p1\"\u003ePower Output: 150W x 2 at 8 Ohms; 150W x 2 @ 4 Ohms\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eGain: X 28 (RCA); X 52 (XLR)\u003c\/li\u003e\n\u003cli class=\"p1\"\u003eInput Impedance: 23.5k Ohms\u003c\/li\u003e\n\u003cli\u003e12V trigger input.
