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.

I don’t believe Paul (of Clear Day Cables) is making cables anymore due to his health problems.

I’ve gotten great results trying out Cabledyne Speaker Cables.
($275 for 2.5m) It takes a couple of days for the highs to open up and the base takes another day or two but when it does, it has some of the tightest image focus I’ve heard in my system.

All the best,

I don’t know about a specific cable, as I’m no expert, but why not buy used? You’re asking on a forum for a used marketplace. Cables in this price range are frequently found over 50% off almost brand new. Even new, I was able to negotiate 20% off Audioquest cabling, so definitely don’t accept MSRP. 

As for sound, I think to get suggestions you may need to explain better what sound you’re looking for. For instance, if you want more bass impact, you’ll probably want a lower gauge wire (thicker).  
Try the Discovery Essential if you have a lower level Discovery.  Also Cerious Graphene Extreme.  I am using both.  I prefer the Cerious but the Essential is also excellent
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.
