Do you find anything better about the Emotiva plugs? The Monoprice ones you used before are advertised as copper base material plated in gold. I don't think Emotiva says what the base material is, I would assume it's brass because of this. I prefer copper base material for no objective reasoning at all, I just want copper.
I have used Monoprice bananas on a few cables because I cannot for the life of me find a good 5/16" copper base material, gold plate, Spade connector. I also subjectively prefer Spades for no major reason. I did read an article from a US Navy Electrical Engineer who did some connectivity testing for submarines and found that banana connectors had worse connectivity than bare copper wire.
I am going to use some left over Swan speaker cable that came with my set of Diva speakers. They are only going to my bookshelf system in my bedroom so high dollar parts is not necessary. I just want to sleeve them and make them look really nice out of boredom.
Also, how can I be sure to match the diameter of the sleeving with the diameter of the wire? Are you guys using any type of cotton jacket or another kind of filler? I'm not sure how I should go about filling in the inner volume of the sleeving to have a somewhat tight fit.
