Speaker wire upgrade??

I am running a McIntosh MC 402 to Dali Euphonia MS5 Speakers. I am using the speaker wire the dealer included when I bought the Amp - they are Ultralink Excelsior 2.4. Based on a web search these retail for around $170 or so depending on the store. They are also 12 feet and I only need 8.

I read lots about the importance of speaker wire on this site and am wondering if I could do better and spend not more than $500. Any thoughts from follow "goners"?
