I would steer clear of the eBay jobs.
I have been looking at the braided Kimber, as the inductance is low.
But I usually use the Magomi 12 or 13 ga stuff which is 4 wire (2 pair) and just put on the ends. I ordered 40 or maybe 50 feet of it, as well as mic cable and Nuetrik RCAs. So all that gear is allegedly now in the mail.
A speaker cable as DIY is pretty easy of one is on a budget and they sound just dandy to a iron-fist and lead-ear.
