Inexpensive speaker cables

Zu are my new favorite cable. You can buy them direct or buy the earlier models at a discount on Ebay or Agon. 
I also use Cable solutions for my subs, but wouldn't rule them out for speakers.

+1 for Zu Audio cables. The Missions aren’t bad for the money but if you can pony up for the Event MkI, which they still have on sale, go for it.

If that is too dear, price wise, try some Supra Ply 3.4W speaker cable. They're stranded, tinned, high purity copper wire and impart a very musical perspective. Not the most accurate but they can sound very romantic and engaging. 

All the best,
Nonoise

At the price range I would also try Clear Day Cables. Paul is a great
guy to deal with and most likely let you demo his cables before you buy.
His cable offers a lot of band for the buck.
