We are in the process of upgrading various pieces of demo equipment, and are selling our AudioQuest Type 8 speaker cables. These cables employ advanced materials and geometries to deliver superior audio quality, and at this price, you'd be hard pressed to find a better cable. See below for features/specs from the original AudioQuest literature:
"Type 8 uses a carefully finessed combination of Long-Grain Copper (LGC) and extremely high purity Perfect-Surface Copper (PSC) conductors. The gauge of this cable is 2 x 12 AWG with a 10mm outer diameter.
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.
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 compared to OFHC, OCC, 8N, and other coppers.
Sophisticated Circular-Array Geometry The relationship between conductors defines some of a cable's basic electrical values (capacitance and inductance). Independent of these values, the relationship between conductors can be varied in ways that greatly effect performance. The circular-spiral construction of Type 8 allows for significantly better dynamic contrast and clarity than if the same conductors were run in parallel or as multiple twisted pairs.
Spread Spectrum Technology (SST) Any single size or shape of conductor has a characteristic distortion profile. Even though radially symmetrical conductors (solid round or tubular) have the fewest discontinuities, each size still has a sonic signature. Type 8 uses a precise combination of four different size conductors in order to significantly reduce the audibility of these character flaws."
