This Dual-Triple cable does not look normal on the outside, and it is not at all normal on the inside. Amazingly clean and effortless performance is made possible by a sophisticated combination of extraordinary materials and extremely refined design. Solid Conductors: Eliminate harshness and confusion due to strand interaction. Long-Grain Copper/Perfect-Surface Copper: Rocket 33 uses a carefully finessed combination of Long-Grain Copper (LGC) and extremely high-purity Perfect-Surface Copper (PSC). LGC has fewer oxides within the conducting material, less impurities, less grain boundaries and definitively better performance. The astonishingly smooth and pure PSC further eliminates harshness and greatly increases clarity. Dual-Triple Geometry: The relationship between conductors defines a cables 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 Dual-Triple construction of Rocket 33 allows for significantly better dynamic contrast and information intelligibility than if the same conductors were 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 particular size does have a sonic signature. SST is a method for significantly reducing the awareness of these character flaws by using a precise combination of different size conductors. The six different SST-determined conductor sizes used in Rocket 33 allow an exceptionally clear, clean and dynamic sound. Bi-Wiring: Rocket 33 is an exceptional Single-Biwire cable. When the halves are separated at the speaker end, the Dual-Triple design turns Rocket 33 into a true Double-Biwire set thanks to the magnetic autonomy of each tri-conductor section. On its own, one tri-conductor group would be a little light-weight in performance as it is biased towards treble finesse. The other tri-conductor group is biased toward the bass; its more forceful and lacking ultimate resolution. Together they form a completely optimized full range design. When separated, the Dual-Triple design lets Rocket 33 be a maximum performance Double-Biwire in a single cable. Terminations: AudioQuest offers a wide range of high quality connectors that allow Rocket 33 to be securely attached to any type of equipment. AQ ends are either dull looking gold r 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. Application: The PVC ?pants? on either end of Rocket 33 are marked ?Speaker End? or ?Amp End?. Please use cables in the direction required.
