It is not important nor wise to spend serious amounts of money on cables of any sort until you've got the fundamentals (source components, amps, speakers, etc) of your system down. In the interim there are any number of sub $100 interconnects and equally low cost speaker cables and power cords that will more than suffice. As you can tell from the above discussions, once you get past the initial stuff nobody really knows which is most important. There are numerous opinions, but it's really one of those questions that doesn't have a correct answer.
