This speaker cable is amazing! Really thick and yes it's pure copper (checked). I've used this with Mediabridge banana plugs and it's on the limit of getting through the hole but it can be done with a little effort. The sound is noticeably cleaner on a pair of Focal floorstanding speakers. I used some pre made wires which were quite expensive so you would think they would be good but I find this wire superior. It took about an hour to prepare, but it's worth every minute!
