{"product_id":"nuprimeamgone","title":"NuPrime AMG ONE Mono Power Amplifier (Monoblock), Grey (Each)","description":"\u003cp\u003eThe NuPrime AMG ONE is a Class-D mono power amplifier (monoblock) that delivers 170 watts into 8 ohms and actively reduces distortion with NuPrime's Only Distortion Cancellation design (ODC).\u003c\/p\u003e\u003cp\u003eIn practice: one monoblock amplifies exactly one channel – with full attention, its own power supply, and short signal paths. For stereo, two of them work as a well-matched pair, one per speaker.\u003c\/p\u003e\u003ch2\u003eWhy the AMG ONE?\u003c\/h2\u003e\u003cp\u003eThe ODC design is NuPrime's Class-D topology: it measures distortion and calculates it back out again. The result is a clean, powerful tone that doesn't get harsher at higher levels but stays composed.\u003c\/p\u003e\u003cp\u003eBehind it sits a 250 W toroidal transformer with 22,000 µF of filter capacitance – so plenty of reserve for dynamic peaks. In standby, the amplifier settles for 0.4 watts, which is pleasantly unobtrusive during continuous operation.\u003c\/p\u003e\u003ch2\u003eWhat you hear\u003c\/h2\u003e\u003cp\u003e170 watts into 8 ohms, 220 watts into 4 ohms, up to 260 watts at peak: that lets a pair of AMG ONEs drive even more demanding speakers under full control. Especially in the bass, the power shows up as precision rather than pushiness.\u003c\/p\u003e\u003cp\u003eThe very low output impedance (4 mΩ) gives a firm grip on the speaker – diaphragms follow the signal instead of ringing on. The NJR MUSES8820 op-amp in the input stage and the 600 kHz switching frequency keep resolution high.\u003c\/p\u003e\u003ch2\u003eVideo\u003c\/h2\u003e\u003cdiv style=\"position:relative;padding-bottom:56.25%;height:0;overflow:hidden;max-width:100%;\"\u003e\u003ciframe src=\"https:\/\/www.youtube.com\/embed\/73BP7kJZn-I\" title=\"NuPrime Audio AMG ONE\" style=\"position:absolute;top:0;left:0;width:100%;height:100%;border:0;\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" allowfullscreen\u003e\u003c\/iframe\u003e\u003c\/div\u003e\u003ch3\u003eWho is the AMG ONE for?\u003c\/h3\u003e\u003cp\u003eFor anyone looking for a compact, powerful power amplifier and wanting the benefit of separate monoblocks – ideal together with a high-quality preamp such as the AMG DAC or the AMG PRA. If you value clean channel separation and short signal paths, this is for you.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eStraight talk:\u003c\/strong\u003e Don't look here for digital gimmicks, streaming, or a DAC – the AMG ONE is a pure power amplifier and needs a preamp in front of it. If you want an all-in-one device, you're better served by an integrated amplifier. If you deliberately separate your power amps, this is exactly right.\u003c\/p\u003e\u003ch2\u003eOur verdict\u003c\/h2\u003e\u003cp\u003eThe AMG ONE is a surprisingly powerful, compact monoblock with NuPrime's clean Class-D signature. HiFi-IFAs calls the AMG ONE monos the perfect choice for music lovers who want to make almost no sonic compromises – at a more than fair price. The Absolute Sound listed the AMG ONE in its 2024 Buyer's Guide among the biggest high-end bargains. We at HD Zürisee in Wädenswil appreciate how easily it slots into an existing chain.\u003c\/p\u003e\u003ch2\u003eTechnical data\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDesign:\u003c\/strong\u003e Class-D mono power amplifier (monoblock), ODC design\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput stage:\u003c\/strong\u003e NJR MUSES8820 op-amp, 600 kHz switching frequency\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower supply:\u003c\/strong\u003e 250 W toroidal transformer, 22,000 µF filter capacitance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power (RMS):\u003c\/strong\u003e 170 W @ 8 Ω, 220 W @ 4 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput power (peak):\u003c\/strong\u003e 210 W @ 8 Ω, 260 W @ 4 Ω\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGain:\u003c\/strong\u003e 26.44 dB (voltage gain 21)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSensitivity:\u003c\/strong\u003e 1.7 Vrms\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInput impedance:\u003c\/strong\u003e 47 kΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput impedance:\u003c\/strong\u003e 4 mΩ\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTHD \/ S\/N (typical):\u003c\/strong\u003e @5 W 0.003 % \/ 95 dB · @50 W 0.004 % \/ 105 dB · @100 W 0.03 % \/ 110 dB\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrequency response:\u003c\/strong\u003e 10 Hz – 50 kHz (-3 dB)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTrigger:\u003c\/strong\u003e IN (\u0026gt; 5 V\/200 mA) and OUT (12 V)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandby power:\u003c\/strong\u003e 0.4 W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains voltage:\u003c\/strong\u003e 115 \/ 230 VAC, switchable\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (W × H × D):\u003c\/strong\u003e 235 × 55 × 285 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.9 kg\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Grey\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e 2 years\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\u003cp\u003e\u003cstrong\u003eHow much power does the NuPrime AMG ONE have?\u003c\/strong\u003e\u003cbr\u003eAs a monoblock, the AMG ONE delivers 170 watts into 8 ohms and 220 watts into 4 ohms (RMS), up to 260 watts at peak. That lets a pair drive even more demanding speakers under full control, without sagging during loud passages.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need two AMG ONE for stereo?\u003c\/strong\u003e\u003cbr\u003eYes. The AMG ONE is a mono power amplifier (monoblock) that amplifies exactly one channel. For classic stereo operation you therefore need two units – one per speaker. The benefit is short signal paths, a separate power supply per channel, and very clean channel separation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhich preamp suits the AMG ONE?\u003c\/strong\u003e\u003cbr\u003eThe AMG ONE is a pure power amplifier and needs a preamp or preamplifier in front of it. From NuPrime's own range, the AMG PRA or the AMG DAC with built-in volume control are good options. We're happy to help you work out which combination fits your setup.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat does the ODC design of the AMG ONE do?\u003c\/strong\u003e\u003cbr\u003eThe Only Distortion Cancellation design (ODC) is NuPrime's Class-D topology, which specifically reduces distortion. Together with the 250 W toroidal transformer and 22,000 µF of filter capacitance, it delivers a clean, powerful foundation with very low standby consumption.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy buy the NuPrime AMG ONE at HD Zürisee?\u003c\/strong\u003e\u003cbr\u003eBecause a power amplifier only makes sense in the right combination.
