I agree with Steuspeed. You spent how much on your gear and you wish to fine tune it using HD wire?
I have used the HD wire, it is OK, not great. Give it a try though, as mentioned it is a cheap DIY project and is fun. If you don't have enough cash at the moment for better cables, this will hold you over. When you get ready to experiment with other cables, give the Cable Company a call and borrow cables to try from them.
