Help with speaker cable under $500 for new system

Hi...HELP!

I know very little about speaker cable and have never owned any but "budget" cables. I have just bought the following:
Hegel 160 Integrated Amp
ATC SCM 19 v2 sealed box speakers

Will be set up in a large open greatroom with speakers about 10 feet apart (need one cable about 4 feet and the other about 12 feet). I listen primarily to jazz, blues and reggae at CD quality streamed from an iMac to the Hegel.

Help me find the right speaker cables under about $500 a pair? Am happy to stay with Bluejeans or Monoprice if the difference won't be really noticable.

THANKS!
