great a bit off topic but i guess its somewhat related than opening a new thread. I'm thinking about switching the powercable on my Swans MKIII which using a C7 outlet. I bought a PS Audio C7 power punch power cable and didn't realize it was a C7 polarized meaning one side is rounded and the other is squared. Will it still fit in my speakers? If it doesn't, I heard someone using a knife it shave the squared side off making it round, but don't know if this is safe... Need some help guys.
