{"product_id":"audioquest-suregrip-500-lautsprecher-stecker","title":"AudioQuest SureGrip 500 Speaker Connectors","description":"\u003cp\u003eThe AudioQuest SureGrip 500 is a speaker connector with a solid, one-piece conductor made of high-purity Purple Copper, available as a banana plug or multi-spade, and in sets of 4 or 6. The silver layer sits directly on the copper, and the cable is cold-crimped rather than soldered.\u003c\/p\u003e\n\u003cp\u003eBetween the 300 series and the 500 series there's no marketing leap, but a material change: away from beryllium copper, toward a solid piece of Purple Copper with no seams, sleeves, or interlayers.\u003c\/p\u003e\n\u003ch2\u003eWhy the 500 series?\u003c\/h2\u003e\n\u003cp\u003eEvery connector is a break in the signal path — the only question is how many parts and metals it's made of. The SureGrip 500 is machined from a single piece, with no brass sleeve and none of the usual nickel undercoat beneath the precious-metal layer. AudioQuest calls this directly applied silver \"Hanging Silver.\" Add to that the Cold-Weld principle: a set screw cold-presses the cable end into the conductor, with no solder as a third metal in between.\u003c\/p\u003e\n\u003ch2\u003eSet of 4 or 6 — what you get\u003c\/h2\u003e\n\u003cp\u003eThe set sizes aren't a bulk discount, but two different use cases. AudioQuest calls the \u003cstrong\u003e4-piece set\u003c\/strong\u003e \"Full Range\": four connectors terminate a normal speaker cable run completely, two at the amplifier and two at the speaker. The \u003cstrong\u003e6-piece set\u003c\/strong\u003e is called \"BiWire\": two connectors at the amplifier, four at the bi-wireable speaker. Both sizes cover \u003cstrong\u003eone\u003c\/strong\u003e speaker each — for a stereo pair, you need two sets.\u003c\/p\u003e\n\u003ch3\u003eWho is the SureGrip 500 for — and who isn't it for?\u003c\/h3\u003e\n\u003cp\u003eFor systems where the speaker cable itself is already decent and the contact point shouldn't remain the weakest link. Gauges up to 9 AWG fit. Honestly: if the other end still has bundled stranded wire hanging off it, upgrade there first — a solid Purple Copper connector on thin bell wire is expensive cosmetics. We'll tell you where the bigger lever is in your setup.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe 500 series is the point where connector quality can be justified technically rather than merely claimed: one conductor, one metal, a defined clamping pressure. Anyone who already has a good cable lying around gets the matching termination here. At HD Zürisee in Wädenswil, we clarify plug type and set size beforehand so nothing surplus ends up in a drawer.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e speaker connector, banana or multi-spade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries:\u003c\/strong\u003e AudioQuest SureGrip 500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConductor:\u003c\/strong\u003e solid, one-piece, high-purity Purple Copper\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoating:\u003c\/strong\u003e silver, directly applied (\"Hanging Silver,\" no interlayer)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClamping principle:\u003c\/strong\u003e Cold-Weld — set screw cold-presses the cable, solder-free\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCable gauge:\u003c\/strong\u003e up to 9 AWG (approx. 6.6 mm²)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBanana connection:\u003c\/strong\u003e common standard banana jacks\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMulti-spade connection:\u003c\/strong\u003e screw binding posts from 6.4 to 7.9 mm (1\/4\" to 5\/16\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet sizes:\u003c\/strong\u003e 4-piece (\"Full Range\") or 6-piece (\"BiWire\"), each for one speaker\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded:\u003c\/strong\u003e 4 or 6 connectors, depending on the variant chosen\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat is the 6-piece set for?\u003c\/h3\u003e\n\u003cp\u003eFor a bi-wireable speaker. There, the cable splits at the speaker into two pairs of terminals: two connectors go to the amplifier, four to the speaker. That's why AudioQuest lists this set size as \"BiWire.\" Without bi-wiring, the 4-piece set — which the manufacturer calls \"Full Range\" — is enough.\u003c\/p\u003e\n\u003ch3\u003eWhat's different about Purple Copper compared to the 300 series material?\u003c\/h3\u003e\n\u003cp\u003eThe 500 series uses a solid, one-piece conductor of high-purity Purple Copper; the 300 series uses a body made of beryllium copper. The difference lies in purity and construction: no seam, no sleeve, no second metal in the signal path. In both cases, the silver layer sits directly on the conductor with no interlayer.\u003c\/p\u003e\n\u003ch3\u003eDoes the multi-spade fit under my binding post?\u003c\/h3\u003e\n\u003cp\u003eThe 500 series' spade lug is designed for posts with a 6.4 to 7.9 millimeter shaft diameter, and so fits the vast majority of common screw binding posts. No spade lug works on pure sockets without threads — there, use the banana version instead.\u003c\/p\u003e\n\u003ch3\u003eWhy get the SureGrip 500 at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause we treat cable and connector as one component, and we'll handle the termination for you if you like.
