{"product_id":"hd-one-high-end-lautsprecherkabel-stereo-bi-amp","title":"HD ONE High-End Speaker Cable, Stereo, Bi-Amp","description":"\u003cp\u003eThe HD ONE in the bi-amp version is a hand-assembled high-end speaker cable that connects each speaker to two separate amplifier channels via four dedicated conductors.\u003c\/p\u003e\n\u003cp\u003eIt's built at HD Zürisee in Wädenswil, cut to your desired length: silver-plated strands for the treble, tinned ones for the bass.\u003c\/p\u003e\n\u003ch2\u003eWhy the HD ONE in bi-amp?\u003c\/h2\u003e\n\u003cp\u003eHonestly: a cable doesn't make your sound better – one that's too thin makes it worse. The HD ONE keeps resistance low and capacitance low. In the bi-amp version, two separate conductor pairs run per speaker to the treble and bass terminals, each on its own amplifier channel.\u003c\/p\u003e\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eA ready-made stereo set for genuine bi-amping: per speaker, four solid spread-type banana plugs on the amplifier side, four on the speaker side, all 24-carat gold-plated. Stripping, twisting strands, quiet cursing – all eliminated.\u003c\/p\u003e\n\u003ch3\u003eWho is the bi-amp version for?\u003c\/h3\u003e\n\u003cp\u003eFor you, if your speakers have two pairs of terminals (bridges removed) and two amplifier channels are available per side. Straight talk: without that second channel, bi-amping makes no sense – then the single-wire or bi-wire version is the more honest choice. And honestly: it remains a refinement, not a transformation.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eThe most uncompromising version of our house cable: plenty of copper, separate branches, solid connectors. It rewards systems with two amplifier channels per side – and leaves all others cold.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eType: High-end speaker cable for bi-amping, assembled stereo pair\u003c\/li\u003e\n\u003cli\u003eStructure: 8 × 2.5 mm² high-purity, oxygen-free copper (OFC) – four conductors per speaker\u003c\/li\u003e\n\u003cli\u003eTreble branch: Silver-plated OFC strands\u003c\/li\u003e\n\u003cli\u003eBass branch: Tinned OFC strands\u003c\/li\u003e\n\u003cli\u003eInsulation and jacket: High-density polyethylene, fleece binding, vibration-damping soft fabric jacket\u003c\/li\u003e\n\u003cli\u003eCapacitance: Very low\u003c\/li\u003e\n\u003cli\u003eConnectors: Solid spread-type banana plugs, 24-carat gold-plated – four per speaker on the amplifier side, four on the speaker side\u003c\/li\u003e\n\u003cli\u003eLengths: 2 × 0.5 m to 2 × 5.0 m in 0.5 m steps, special lengths on request\u003c\/li\u003e\n\u003cli\u003eAssembly: By hand in Wädenswil\u003c\/li\u003e\n\u003cli\u003eScope of delivery: 1 pair HD ONE bi-amp speaker cable, marking rings, safety instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eWhat's the difference between bi-wiring and bi-amping?\u003c\/h3\u003e\n\u003cp\u003eBi-wiring only separates the cable paths: one amplifier feeds the treble and bass terminals via two separate conductor pairs. With bi-amping, each branch additionally gets its own amplifier channel. The crossover in the speaker stays active in both cases – so you don't need an external crossover, but you do need speakers with two pairs of terminals.\u003c\/p\u003e\n\u003ch3\u003eWhen does bi-amping actually pay off?\u003c\/h3\u003e\n\u003cp\u003eWhen you already have two amplifier channels per side and speakers with two pairs of terminals. Then you gain control in the bass and a bit more calm in the treble, because the branches no longer share one amplifier stage. If you'd first have to buy a second amplifier stage, you're better off investing in placement and room acoustics.\u003c\/p\u003e\n\u003ch3\u003eWhat length should I choose?\u003c\/h3\u003e\n\u003cp\u003eMeasure the actual cable path along the wall, skirting board and furniture, not the straight-line distance, and add a bit of slack. The HD ONE is available from 2 × 0.5 to 2 × 5.0 metres in half-metre steps, special lengths on request. Both sides are assembled to the same length.\u003c\/p\u003e\n\u003ch3\u003eDo the banana plugs fit my connections?\u003c\/h3\u003e\n\u003cp\u003eThe solid spread-type banana plugs fit all common binding posts on amplifiers and speakers. Safety sockets with a plastic cap need to be opened or removed beforehand. If your devices only have screw terminals without banana sockets, let us know before ordering – then we'll clarify the assembly with you in advance.\u003c\/p\u003e\n\u003ch3\u003eWhy buy HD ONE Bi-Amp at HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause the HD ONE is our own cable: we developed it, we build it in Wädenswil, and from many systems we've looked after we know exactly where bi-amping really makes a difference. Call, write to us, or send us your equipment setup via WhatsApp – we'll tell you honestly which version suits you.\u003c\/p\u003e\n\u003ch2\u003eGoes well with\u003c\/h2\u003e\n\u003cp\u003eYou'll find the second amplifier channel among the \u003ca href=\"\/en-ch\/collections\/endstufen\"\u003epower amplifiers\u003c\/a\u003e, and the right speakers among the \u003ca href=\"\/en-ch\/collections\/standlautsprecher\"\u003efloorstanding speakers\u003c\/a\u003e and \u003ca href=\"\/en-ch\/collections\/regallautsprecher\"\u003ebookshelf speakers\u003c\/a\u003e.
