I have been at this a long time and have participated in several comparative tests using standard 18g zip cord v various expensive audio cables. Neither I nor anyone else who participated in these tests ever heard a significant difference. I have it on some authority that several top name speaker venders use expensive speaker wire during their demonstrations because it is expected not because they believe it makes any difference. The only place where I found the type and design of wire makes any difference is in certain HDMI applications. This does not mean you have to go with expensive HDMI cables, just that some work better in some applications as far as the handshake between hardware is concerned.
