Crystal Clear Audio Cables for sure! They beat the Wireworld Platinum line hands down. Especially their Magnum Opus tier:

What speaker cable made a major difference in the sound quality of your speakers??
I am curious what speaker cables made a big "jaw dropping difference" in the sound quality of your current speakers. What most impressed you about the difference; that is, overall musicality, tighter, deeper bass, midrange clarity and soundstage depth, etc.etc.
Keep the price of the speaker cables chosen or auditioned at between $800- $1000 or from $1000-$1500. Was the cable bought new or used??
Thank you, SJ
