Trying to make 0.5m long cable to connect unbalanced XLR preamp output to balanced XLR poweramp input. Plan to use Neutrik NC3FXB XLR's from Canford, but don't know which of the Belden cables they have listed is best [URL=http://www.canford.co.uk/commerce/category_3000078_3000006.aspx](Canford.co.uk Cables)[/URL]. Need to get my total order over £25 to get free shipping so no need to skimp!
