With Harmonix speaker cables, the answer is: all of it! These cables are faithful to the original recording, adding a previously-unheard roundness to the sound color, and a breathtaking depth and concentration. The difference is awe-inspiring! Increased expansiveness is evident the instant you turn on the music. You’ll wonder where all the extra sound came from. It was always there in your system to begin with; Harmonix speaker cables just help bring it out. After years of researching cable conductor materials, Harmonix discovered that each type of conductor has a specific electronic resonance signature, and resonates in a specific pattern. Our engineers found a way to compensate for this resonance so that it improves, rather than interferes with, signal quality. They incorporated this technology into the HS-101 speaker cables. Now more and more audiophiles are hearing just how good their audio systems actually sound.
