AudioQuest Indigo+ 8′ Bi-Wire Speaker Cables – Made in USA

AudioQuest Indigo+ 8-Foot Bi-Wire Speaker Cables – Solid FPC and Solid LGC Copper Hyperlitz, Radique Audio Banana Termination, Made in USA

An eight-foot pair built on the legendary AudioQuest Indigo+ core wire, re-terminated here for true bi-wire with our own gold-plated banana plugs.

Solid-Core Conductors

Almost all speaker cable is stranded copper, because stranded is cheap and easy to make. AudioQuest went the other way, which is why the Indigo+ is still highly sought after by audiophiles decades after it left production. The Indigo+ is built from solid-core conductors, spiraled in AudioQuest’s Hyperlitz geometry so that each conductor keeps a constant relationship to the others down the length of the run. The point of it is that strand-to-strand interaction — the small, constantly changing contacts between adjacent strands in an ordinary cable — is designed out rather than tolerated.

The Hybrid Metals

The other thing worth knowing is the metal, and it is printed right on the jacket: solid FPC copper and solid LGC copper, together, in the same cable. This is the point in AudioQuest’s range where they began mixing conductor grades rather than building the whole cable from one, on the same principle as bypassing a large capacitor with a small high-quality one. Eight conductors in total, in several different gauges, each individually insulated and held in a fixed spiral relationship to the others. Made in the USA, back when that was still the ordinary answer rather than a selling point.

Re-Terminated on Our Bench

These have been re-terminated in our own shop for true bi-wire, in a two-plug to four-plug layout. The core was stripped back to fresh copper and fitted with Radique Audio premium gold-plated banana plugs: a single pair at the amplifier end, splitting cleanly to two pairs at the speaker end. The breakout is custom-dressed in heavy flexible jacketing, with colour-coded heat-shrink at every grouping, and each cable ships with a Radique Audio strap. It is worth looking at the photographs — this is the part that does not photograph as ordinary.

How Bi-Wiring Works

Run this way, the jumper plates come off your speakers entirely. Each cable feeds the low-frequency and high-frequency binding posts on its own conductors, all the way back to the amplifier, which is the whole point of owning a bi-wireable speaker in the first place.

Why Eight Feet

Eight feet is the length most people actually need. Long enough to run an amplifier along one wall and speakers along another, short enough not to coil a surplus loop behind the rack, and long enough to keep both channels equal — which matters more than most people think, since matching cable lengths left and right is free and costs nothing to get right at purchase.

A Word on Weight

Be warned that these are heavy. A cable this substantial does not drape politely, and it wants a moment’s thought about how it leaves the binding post.

Condition

The cables are in very good condition. The terminations are new.

Who These Are For

If you are running decent speakers on whatever wire came in the box, this is the upgrade that costs the least and is easiest to hear the argument for.
