COPPIA CAVI DIFFUSORI AUDIOQUEST OAK DA 3,5 METRI
GARANZIA UFFICIALE ITALIA
TERMINAZIONI Banane o Forcelle
Oak uses extremely high purity Perfect-Surface Copper+ (PSC+) conductors. All conductors are solid, which prevents strand interaction, a major source of distortion. 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. The superior purity of PSC+ further minimizes distortion caused by grain boundaries, which exist within any metal conductor.
DIELECTRIC-BIAS SYSTEM (DBS, US Pat #7,126,055):
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 pack's batteries lasts for years. A test button and LED allow for the occasional battery check.
COUNTER SPIRALING “TREE FEATURE” GEOMETRY:
Oak and the other AudioQuest “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, and thoroughly consistent. 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 Oak allow an exceptionally clear, clean and dynamic sound
The five negative conductors in Oak 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 Oak to be securely attached to any type of equipment. Quality is in the low distortion sound, not necessarily in the eye-candy effect. AudioQuest 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. AudioQuest PK-spade lugs are soft because better metal is soft, and facilitates a higher quality connection.
