Why Bi-Wire? In a single wired system unwanted mechanical and electrical resonances appear as distortion at both sets of speakerterminals. Due to the impedance of the cables these distortions will not be entirely cancelled by the amplifier, instead modulating betweenthe two sections of the speaker system, degrading sound quality. With bi-wiring this interaction is minimised as signal distortion is “seen” atthe amplifier's output where it can be more effectively cancelled. The purpose of bi-wiring is to present a clean signal at both the bass andtreble speaker terminals.Enhanced Bi-Wire GeometryAll the new bi-wire cables in the Original Range feature an enhanced geometry that minimises cableinductance by precisely spacing opposing sets of conductors. This provides greater high frequencystability, allowing the amplifier to maintain tight control of the speakers throughout the audible range.QED Micro Bi-WireMicro Bi-Wire combines the true performance benefits of bi-wiring with discreet,low-profile double figure “8” construction, small enough to be easily concealedin nearly every domestic situation.

The Materials & TechnologyTo make a hi-fi cable that works correctly you don’t need black magic. You don’t need exotic theories and rare materials. But you do need goodscience. During 1994 QED conducted the most extensive ever scientific investigation into the effects of speaker cable on hi-fi system performance.You can read the results in the Genesis Report*. You can hear the results whenever you listen to QED cables and interconnects.99.999% Oxygen Free Copper ConductorsOxygen content degrades the purity of copper. All QED cables feature Oxygen Free High Purity Copper conductors with a purity of at least 99.999%.This gives significant audible improvements over standard grade TPC (Tough Pitch Copper) conductors, which have over 5 times the level of Oxygenfound in QED cables.Silver Plated 99.999% Oxygen Free Copper ConductorsSilver plated OFHPC provides even greater conductivity. Because it is less susceptible to oxidation it provides long term performance benefits.Sonically it helps to deliver superb resolution and delicacy, especially when used as part of a ‘high-end’ system.Spiral Lay StrandingMost cables have bunches of conductors with no defined geometric configuration. They need thicker insulation (dielectric) to allow for the variationin conductor diameter caused by this bunch stranding. QED Silver Anniversary cables feature Spiral Lay Stranding of the conductors which has amore consistent shape allowing the use of thinner dielectric. This helps to minimise signal losses into the insulation.True Concentric StrandingThe Profile Series takes stranding technology a step further. True Concentric Stranding uses hexagonally laid strands which means that only theminimum thickness of dielectric need be applied to maintain integrity of insulation. This further reduces signal losses to vanishingly low levels.Low Density Polyethylene InsulationMinimising the cable signal losses that occur between amplifier and speaker is crucial. QED Low Density Polyethylene Insulation is proven todramatically reduce signal leakage.Foamed Low Density Polyethylene InsulationAir is probably the most stable and effective insulator known. By introducing air into the insulation, known as foaming, it further enhances it’s effectiveness.Foamed Low Density Polyethylene Insulation is utilised wherever possible in the Qunex range to ensure near ideal signal integrity.All QED cables have ‘free space’ designed into the cable profile. This ensures the conductors are wherever possible surrounded by the least amount of insulation, so soundquality is further enhanced.Screening BraidA screening braid is made up of a number of copper strands woven together to provide a screen against external noise. It can also be used as aneffective signal return. This type of screening offers the advantage of a lower resistance but does not normally give 100% conductor coverage.Aluminium Mylar Screening FoilSheet Mylar insulation with an Aluminised coating on one side is wrapped around insulated conductors like a tape. It enhances screening by giving100% coverage. It has high resistance and is difficult to terminate, therefore it is often used in conjunction with a braid or drain wire.Balanced GeometryBalanced Geometry refers to the signal and return conductors being of the same type and of a symmetrical configuration. The twisted balancedconfiguration uses two conductors. When conductors are twisted together there is some cancellation of the sound degrading field surrounding eachconductor, since the field inducing current in each conductor is flowing in opposite directions.Quad Balanced GeometryA Quad balanced configuration utilises four separate conductors, two signal and two ground. Using four conductors reduces the resistance andinductance of the cable. The screen is always open ended i.e. not connected at one end, to ensure there is no current flow, causing asymmetry withinthe cable.Selective Twist RatesTwist rates are designed to enhance field cancellation, ensure consistent grouping, reduce inductance and minimise proximity effect. They also havea large effect on the flexibility of the cable.
