PERFECT-SURFACE COPPER+ / PERFECT-SURFACE SILVER:
Redwood uses a carefully finessed combination of Perfect-Surface Copper+ (PSC+) and extremely high purity Perfect-Surface Silver (PSS) conductors in a Self-Shielding Counter-Spiral HyperLitz. Solid conductors prevent strand interaction, which is the greatest single source of distortion in an audio cable or an AC power cable. Surface quality is critical because a conductor can be considered as a rail-guide for both the electric fields within a conductor, and for the magnetic fields outside the conductor. The astonishingly smooth and pure Perfect-Surface eliminates harshness and greatly increases clarity compared to OFHC, OCC, 8N and other coppers. Extremely high-purity PSS further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
DIELECTRIC-BIAS SYSTEM (DBS, US Pat #7,126,055):
All insulation slows down the signal on the conductor inside. When insulation is un-biased, it slows down parts of the signal differently, a big problem for very time sensitive multi-octave audio.
AudioQuests 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. Sound appears from a surprisingly black background with unexpected detail and dynamic contrast. The DBS packs batteries will last for years. A test button and LED allow for the occasional battery check.
COUNTER SPIRALING TREE FEATURE GEOMETRY:
Redwood and the other AQ Tree Feature cables have an inner circular array of positive conductors spiraling in one direction. Around this inner group, are the negative conductors, spiraling in the opposite direction. Even while the positive and negative conductors are crossing each other instead of being parallel, the relationship between the positive and negative groups is fixed and non-changing, adhering to one of AudioQuests most basic design tenets: consistency. The result is an astonishing clarity, like focusing a camera lens you had no idea was so far out of focus.
SST (Spread Spectrum Technology):
Any single size or shape of conductor has a specific distortion profile. Even though radially symmetrical conductors (solid round or tubular) have the fewest discontinuities, any particular size does have a sonic signature. SST uses a precise combination of different size conductors in order to significantly reduce the audibility of these character flaws. The four different SST-determined conductor sizes used in Redwood allow an exceptionally clear, clean and dynamic sound.
The five negative conductors in Redwood are insulated with partially conductive carbon-loaded polyethylene. This remarkable material damps radio-frequency garbage from being fed back into the amplifier. The sonic benefit is exactly the same reduction in hash and better dimensionality that comes whenever RF garbage is reduced in an audio circuit.
AudioQuest offers a wide range of high quality connectors that allow Redwood to be securely attached to any type of equipment. Quality is in the low distortion sound, not necessarily in the eye-candy effect. AQ ends are either a dull looking gold or silver because these metals are plated directly over the connector. There is no shiny and harsh sounding nickel layer underneath. AQ PK-spade lugs are soft because better metal is soft, and facilitates a higher quality connection. For pieces requiring a banana plug or BFA connector the AQ PK-BFA/Banana provides unprecedented performance over conventional brass versions.
When possible, running separate conductors or separate cables to the treble and bass halves of a speaker will considerably reduce distortion. BiWiring works because cable causes distortion, which can be minimized by keeping the bass energy out of the treble cable. Redwood is an ideal full-range cable. It can also be used as a double pair for maximum benefit from BiWiring. Redwood has also been designed to make it possible to Single-BiWire. The five conductors per polarity have been chosen and arranged so that they may be divided into two groups, allowing Redwood to be prepared with four connections on the speaker end.
