Cables for Canton RC-L Speakers

I have a pair of Canton RC-Ls. What 's the best speaker cable for these speakers?
Friend of mine had a good results with MIT-2 bi wire and later, even better with MIT MH-750 plus! I hope this will help?
Something fairly warm. I'm using Straightwire Silver Surfer (bi-wired) with my Cantons. This has been an excellent match for me.
