{"product_id":"audioquest-nrg-x3-netzkabel-c13","title":"AudioQuest NRG-X3 Power Cable (C13)","description":"\u003cp\u003eThe AudioQuest NRG-X3 is a three-pin power cable with a C13 coupler that supplies hi-fi components with a ground conductor and higher current demand.\u003c\/p\u003e\n\u003cp\u003eC13 is the connector the vast majority of hi-fi devices carry — three contacts in the typical cold-appliance trapezoid shape. That makes the X3 the workhorse of the NRG entry class: the same design as the smaller X2, but with a larger gauge, grounding, and correspondingly more reserve.\u003c\/p\u003e\n\u003ch2\u003eWhy the NRG-X3?\u003c\/h2\u003e\n\u003cp\u003eBecause an amplifier during music playback doesn't draw a steady current, but in bursts. A cable that's too thin holds back exactly those bursts. The NRG-X3 works with direction-controlled Long-Grain Copper (LGC) in a Semi-Solid Concentric geometry: a few substantial strands in one fixed layer that never swap position within the cable. Less grain distortion in the copper, less interaction between strands, cold-welded contacts instead of solder joints — none of this is magic, all of it is solid engineering.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eA cable that doesn't stand out in everyday use — and that's exactly the point. Where a bundled little cord used to hang, the bass sounds a bit tidier after the swap, transients arrive with more definition, and the soundstage loses some restlessness. The effect isn't a curtain lifting; it's a noise floor getting quieter.\u003c\/p\u003e\n\u003ch3\u003eWho is the NRG-X3 for?\u003c\/h3\u003e\n\u003cp\u003eFor integrated amplifiers, mains filters, streaming amps, CD players, and anything else with a C13 input that's currently hanging off its original cable. Honestly: if your device has a flat C7 socket, you're in the wrong place here — then you need the NRG-X2 or NRG-Y2. And if you already own a good power cable, don't expect a leap from the X3; it's a first step, not an end goal.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe NRG-X3 is the most sensible answer to the question \"What do I get once the bundled cable has to go?\" It costs little, sits solidly, lasts a long time, and brings calm exactly where manufacturers usually cut corners. Anyone wanting more later will find the next step in the NRG-Y3 and NRG-Z3 — but nobody has to start there.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e power cable, AudioQuest NRG series (entry level), three-pin\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor:\u003c\/strong\u003e Long-Grain Copper (LGC), direction-controlled\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGeometry:\u003c\/strong\u003e Semi-Solid Concentric\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGauge:\u003c\/strong\u003e 1.31 mm² (16 AWG)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCurrent rating:\u003c\/strong\u003e up to 10 A at 220–240 V\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains-side plug:\u003c\/strong\u003e Schuko (CEE 7\/7, three-pin, grounded)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDevice-side connector:\u003c\/strong\u003e IEC C13 (cold-appliance coupler, three-pin)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTermination:\u003c\/strong\u003e cold-welded plug contacts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eJacket:\u003c\/strong\u003e black PVC with red stripes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAvailable lengths:\u003c\/strong\u003e 1 m, 2 m, 3 m, 4.5 m, 6 m\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e 1 power cable in the length selected\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between the NRG-X3 and the NRG-X2?\u003c\/h3\u003e\n\u003cp\u003eThe number of pins, the coupler, and the gauge. The X3 is three-pin, has a C13 cold-appliance coupler, and 1.31 mm² gauge for up to 10 A. The X2 is two-pin with a flat C7 coupler and only 2.5 A. Both share the conductor material and geometry — but not the intended use.\u003c\/p\u003e\n\u003ch3\u003eDoes the NRG-X3 fit my integrated amplifier?\u003c\/h3\u003e\n\u003cp\u003eIf your amplifier has a three-pin C13 socket, yes. That's the case for the vast majority of integrated amplifiers. Very powerful power amps occasionally have a larger C15 or C19 socket — then you need a different cable. Tell us your model, and we'll take a quick look.\u003c\/p\u003e\n\u003ch3\u003eWhat does Semi-Solid Concentric mean?\u003c\/h3\u003e\n\u003cp\u003eInstead of many thin strands in multiple layers, a few substantial strands sit here in a single, concentric layer around a core wire. They're packed tightly and don't swap position within the cable. That reduces the interaction between strands, which AudioQuest sees as a cause of distortion.\u003c\/p\u003e\n\u003ch3\u003eWhich mains plug does the cable have?\u003c\/h3\u003e\n\u003cp\u003eThe European version comes with a three-pin Schuko plug per CEE 7\/7. For Swiss outlets, an adapter is therefore needed depending on the socket. Ask us about your situation before ordering — we'll tell you what you need instead of leaving you to guess.\u003c\/p\u003e\n\u003ch3\u003eWhy order the NRG-X3 at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we don't recommend cables by price tag, but by device. We'll also tell you when a cheaper model is enough — that happens more often than you might like.
