Get a spool of Belkin speaker cable from Partsconnextion.It's OHNOPCC copper with 18 different sized solid core strands individually insulated.
To find the website, it's spelled partsconnexion. And you won't find any Belkin products there. And when you do find current Belkin products, you'll find they haven't done OCC cable for at least four years, more like five. Currently Belkin doesn't even offer speaker cable on their website.
You may be able to find some NOS Belkin OCC cable on eBay, but that's about it. I bought some of the last of this speaker cable from Partsexpress in 2008 when it was on final closeout.
These days at a budget around $500 I'd call the boys at Zu Audio and see what they might do for you.
