The entire signal path is critical to the overall performance of your system.  It has the same impact as any other key component.  Simply stated, your system will only sound as good as its weakest link.  Speaker cables are the final leg of that signal path and any degradation in signal nullifies the quality of components both before and after it.

Reactances such as capacitance, inductance, and resistance will modify the signal being transferred from the amplifier to the speaker.  In fact, the crossover circuits inside your speakers use capacitors, inductor coils, and resistors to divide the frequencies.  The combination of resistance, capacitance, and inductance is a potential source of coloration which can be seen as a distortion of the original signal.

MasterBuilt Performance Line Speaker Cables sound neutral because they have the least reactance due to their U.S. laboratory grade pure copper wire, the highest quality insulation available and proprietary design technology.  Put simply, this is the highest value speaker wire on the market.
