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

If it was Crazy Eddie's idea of insane prices, that would be a different story!!!
Biggest difference and improvement came with my own DIY pure silver cables -- less than $300 -- no terminations.
Klee Acoustics replaced my Kimber Kable Monocle XL’s...By comparison... the Kimbers sounded broke... ie; closed in,lacking in image,sound-staging,resolution, and tone. Of course,this is with my ears and my equipment. ymmv
@sabai - where did you source your silver cable? I've silver interconnects and connecters.. I'd like to try SCs as well.
toddverrone,

I bought 9999 pure silver wire on Ebay. I use no insulation or connectors. I also made one PC using 9999 pure silver wire -- with insulation and connectors.

Are your interconnects pure silver? With insulation? What connectors are you using?
