I've used SKW products before (interconnects). They're pretty good for what they are. I've not used their speaker cables, though.
Can't go wrong with Amazon. If you don't like them, return them.

I have found a couple of OCC speaker cables that I’m interested in buying and wanted to see if anyone here has any experience with either?
