I would suggest the Home Depot Extension Cord DIY cables that have been discussed extensively over the last couple of years. Do a search here or at AudioAsylum and you'll find plenty of information. They were even positively reviewed by one of the big mainstream Audio mags.
I have a pair and they sound pretty darn good in my high resolution system. They are not the ultimate in resolution, but they are good enough for your current system and the ones you propose for the future.
I think the cable cost about $15. Cut off the ends, cut two sections to length, strip the ends. There are 3 conductors, so connect 2 of them together (white/green) connect to the negative post then connect the remaining black wire to the positive post. If you want, you can add bananas or spades, but it's a waste of money IMHO.
