Our take on the AudioQuest Rocket 88

AudioQuest Rocket 88

Don't let the center sag

In a home theater system, the center channel speaker is the workhorse. If you have a high-performance system — especially one with three matching speakers for left, center, and right — AudioQuest's Rocket 88 center speaker cable will ensure that you hear all the clarity and detail your speakers are capable of. AudioQuest's goal is to transfer signals as faithfully as possible, and it's reflected in their motto: "Do no harm." AQ's secret recipe combines innovative design, top-quality materials, and lots and lots of careful listening.

Rocket science

One of the most important ingredients in a high-quality cable is the metal used for the signal conductors. Rocket 88 uses a carefully optimized combination of AudioQuest's Perfect-Surface Copper and their even-higher-purity Perfect-Surface Copper+. The metal mix is dominated by PSC+, which significantly reduces harshness while increasing clarity. Each of the cable's eight solid conductors is a single unbroken length of pure copper, to minimize signal loss.

AudioQuest's patented Dielectric-Bias System

If you've noticed that when you turn on your audio system it takes a while to really hit its stride sonically, there are a couple reasons. Certainly allowing your electronics to warm up helps, but another factor may lie in your speaker cables. When your system is playing, a charge builds up in the cable's insulation, reducing the amount of electronic noise the cable produces. This charge can dissipate when the cable's not in use, limiting performance slightly until it builds up again.

AudioQuest's active Dielectric-Bias System (DBS) creates a strong, stable electrostatic field which saturates and polarizes the molecules of the insulation. A small battery pack attached to the cable produces a constant 72-volt charge, which maintains optimum bias level, giving you clear, expressive sound from your system every time you turn it on. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

High-quality connectors eliminate the weakest link

Rocket 88 cables feature banana plugs fastened by cold welding — a process that uses extremely high pressure to create solid secure connections that minimize signal loss. By contrast, solder tends to impede the signal, and heating the copper can negatively affect its conductivity.

Features

Solid Perfect-Surface Copper Conductors: Rocket 88 cables use a carefully finessed combination of Perfect-Surface Copper (PSC) and extremely high purity Perfect-Surface Copper+ (PSC+). This combination is designed to eliminates harshness and increase musical clarity. PSC+ further minimizes distortion caused by grain boundaries present in all metal conductors.

Dielectric-Bias System (DBS): All insulation slows down the signal on the conductor inside. When insulation is unbiased, it slows down different parts of the signal differently, a problem for time sensitive multi-octave audio. AudioQuest's DBS creates a strong, stable electrostatic field which saturates and polarizes (organizes) the molecules of the insulation. This minimizes both energy storage in the insulation and the multiple nonlinear time-delays that occur. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS battery packs will last for years. A test button and LED allow for the occasional battery check.

Double Star-Quad Geometry: The relationship between conductors defines a cable's most basic electrical values (capacitance and inductance). However, even when those variables are kept in a reasonable balance, the relationship between conductors can be varied in ways that greatly affect the sound. The Double Star-Quad construction of Rocket 88 cables results in better dynamic contrast and information intelligibility than the same conductors run in parallel.

Spread-Spectrum Technology (SST): Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid or tubular) have the fewest discontinuities, any conductor of a particular size does have a sonic signature. SST is a method of reducing the awareness of these character flaws by using a precise combination of different sized conductors. The four different SST-determined conductor sizes used in Rocket 88 cables allow an exceptionally clear, clean and dynamic sound.
