PROVEN IMPROVEMENT Computer simulations show that not all geometries use their conductors uniformly. As frequencies rise, less of a typical round conductor is used, as presented in the current density plots (far right) for cables of the same cross sectional area, plotted on the same scale. Hollow Oval Design The Analysis Plus hollow oval design clearly uses the conductor more efficiently, and the result is shown in the measured resistance. The hollow oval cables maintain a low resistance value, even at 20 kHz, where the resistance of the round cable has increased dramatically. This increased resistance and slow rise time rolls off the high frequencies, which leads to the difference between the measured signal at the amp and the signal measured at the speaker terminals. This design principle is utilized throughout the Analysis Plus product line, and is the reason why hollow oval cables look and sound better than any competitor’s products.
