Having looked hard at the cost of some of the interconnects and speaker wires (including numerous DIY's) I came across the following information on the Outlaw Audio website. Basically the following sites state that more expensive does not necessarially provide significant increases in quality and in most instances provide no increase. Read for yourself if you like. Sorry, I don't know how to insert the link itself. If you care to, you can go to outlawaudio.com and find the links under the message board for interconnects. Good reading!!
