Belden wire from Blue Jeans Cable?

Thanks for your responses. I've never been a big believer in expensive cables. I presently am using basic Monster 14 gage. Recently tried 12 gage Home Depot extention cord and it softened (dulled) everything considerabley. So now I know they can make a difference. Would like to upgrade, but don't want to spend a fortune. Do you think the Belden would be an improvement over the Monster? Or would it be pretty much the same. Any other suggestions for reasonably priced cable would be welcomed as well. Thanks,
-Bill

Thanks everyone for your comments. Is there any reason to go larger than 14 gage for a 15' run for speakers? Any benefit to 12 or 10 gage for that length? Thanks,
