{"product_id":"audioquest-coffee-usb-kabel","title":"AudioQuest Coffee USB Cable","description":"\u003cp\u003eThe AudioQuest Coffee USB is a USB audio cable with solid-core conductors and 10% silver that, as the first tier of the range, comes with an active 72-volt Dielectric-Bias System. It's the connection for systems where the DAC is no longer the weakest link.\u003c\/p\u003e\n\n\u003ch2\u003eWhy the Coffee?\u003c\/h2\u003e\n\u003cp\u003eThe silver content rises to 10% – and on top of that comes technology that isn't found below this tier. The DBS uses a battery module to apply a constant 72 volts to the insulation, keeping the dielectric polarised so that it stores and releases hardly any energy. A carbon-based 3-layer Noise-Dissipation System and Hard-Cell Foam handle the passive side, silver-plated contacts the transition into the device. The result: a silence between the notes that's hard to give up once you've heard it.\u003c\/p\u003e\n\n\u003ch2\u003eWhat you get\u003c\/h2\u003e\n\u003cp\u003eAn A–B cable in 0.75, 1.5, 3 or 5 m, each with the DBS module fitted. There are no other connector combinations for the Coffee – for that, Carbon and Diamond are available.\u003c\/p\u003e\n\n\u003ch3\u003eWho is the Coffee suited for – and who isn't it?\u003c\/h3\u003e\n\u003cp\u003eHonestly: on a mid-range DAC, most of what the Coffee can do goes unused – there, the Carbon is the smarter investment. This tier makes sense once the DAC, amplifier and speakers already show what a calmer feed can bring. And if your device only has USB-C, the question is settled anyway.\u003c\/p\u003e\n\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eClose to reference, but not uncompromisingly expensive: the Coffee delivers most of what the Diamond can do.

A 72-volt battery applies a voltage to the insulation, keeping the dielectric permanently polarised so it stores less energy. No current flows through the signal conductors – the module works in parallel and is mounted on the cable, without sitting in the signal path.\u003c\/p\u003e\n\u003ch3\u003eHow long does the DBS battery last?\u003c\/h3\u003e\n\u003cp\u003eVery long, since practically no current flows – AudioQuest counts in years, not months. Should the battery ever run down, the cable keeps working, it just loses the added benefit of the bias. We'll source a replacement for you through the distributor – just let us know.\u003c\/p\u003e\n\u003ch3\u003eWhy is the Coffee only available as A–B?\u003c\/h3\u003e\n\u003cp\u003eBecause AudioQuest designed this tier for the classic connection between a computer or streamer and a desktop DAC. If you need USB-C or Micro-B, go for Carbon or Diamond – both come in C–B, C–C and A–Micro B. We'll tell you which tier makes sense in that case.\u003c\/p\u003e\n\u003ch3\u003eCoffee or Diamond – where's the line?\u003c\/h3\u003e\n\u003cp\u003eIn the conductor material. The Coffee works with 10% silver on copper, the Diamond with solid Perfect-Surface Silver. Both carry the active 72-volt DBS. The step up only pays off on high-end DACs; below that, you're better off investing in the source or the power supply.\u003c\/p\u003e\n\u003ch3\u003eWhy order the Coffee from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause a cable at this level deserves an honest assessment, not sales talk. We'll tell you whether your DAC can carry this tier, and we take care of ordering, length and warranty handling.
