J, what you are reading about translates to the many low end cable manufacturer's inability to maintain the 75 or 110 ohm impedance across the required frequencies for more than one length. Run don't walk from any brand in this category. Z.
Optimal digital cable length -- science or voodoo?
I'm doing research toward purchase of a new 75-ohm digital cable to feed a DAC, and I am coming across claims that the "optimal" length for a digital cable is 1.5 meters. Some even claim that, given the exact same brand and model of cable, there's a significant audible difference between a 1-meter and 1.5 meter length. Can an extra half-meter make any improvement? Is there science behind this claim, or is it just voodoo?
