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.

@lak is spot on about the Duelund.  I can make you a set with the 12 gauge Duelund for your budget and you simply cannot do better.  
Ok...now I`m wondering if the Duelund wire would be an improvement over the MIT 750 Music Hose that I`ve been using for the last 15 years or more ???

You can buy 8 meters of Dueland 12 gauge from Parts Connection and twist and strip it yourself and have a quality set of speaker cables for $160 plus shipping.  It is recommended that you use them with bare ends but if you want connectors on the end get them from Chris as well and install them.  I use mine with bare ends.  

If you have to have pre-made then look at the Audio Sensibility Testament cables. Made with OCC copper and Audioquest connectors for C$449 and with the current exchange rate would be about $350.

Wireworld are good for the price. Recently got some Zu LIBTEC from eBay for less than 100.00 delivered and they are very, very good. MacIntosh 2105 driven MMG speakers.
