I have found that Cardas Parsec cables seem to work very well. Each speaker has also a power conditioner attached. I would agree that expensive cords like the Shunyata are probably not necessary: I use some Shunyatas to power my basic amps. I also have old Versalab wood blocks in the line for my speakers’ power. If you can find them anywhere, they are good. if you want to go the inexpensive route, try Pangea cables.
