Best Speaker cable in the $400.00-$500.00 range for 2 meters


I currently have a Rogue Audio Magnum power amp, Rogue Preamp, Triton 5 speakers with 2 SVS subwoofers,
and a Cary Audio CD player. My current speaker cable is by Discovery Cable. Looking to upgrade my cable and
was recommended the Nordost White Lightening which retails for $377.00 a pair for 2 meters and the Nordost Purple Flare, both in the Leif family of Nordost for $500.00 per pair  for 2 meters. In short my budget is
 $500.00 per pair. If there is any other cable that can be recommended in my price range that my be superior
 I would appreciate any suggestions.  Looking for the best use of the $500.00.

You should try Wireworld. I don't claim they are best though, but good value and may mesh well with your system.

How would you describe the discovery cable you are currently using?  I am considering a cable change and am looking for a neutral yet open sound. I understand Discovery cable is quite good overall.

Old model Cerious Tech Cables, Teo audio game changer 2m used, they showed up for $400 at times.used Audioquest cables as well...
Big +1 @mayoradamwest -- you really need to give us some idea of what you're looking to improve upon or at least what aspects of sound reproduction are most important to you or you're just going to get a mishmash of random recommendations that may or may not match with your personal preferences.
