OK I'm sold on interconnects, now speaker cable?

Try Audioquest Type 4 speaker cable in bulk. Terminate yourself or leave raw cable ends and twist together. $4/ft and sounds very good once it has run in for a while (breakin key for this AQ wire). Kimber in bulk is another good choice. I like both of these bulk cables because you are paying for the wire and dialectric and not fancy packaging or connectors.

Or, check out these discontinued AQ cables from HCM Audio:

By some Van Damme cables and put some nice spades on them(bryston.ca)

I just got a pair of Clear Day Solid Core. They only have about 20 hours on them so far and I'm really pleased with them. He is also a great guy to deal with.

Kimber 8TC is my favorite.

I second the Clear Day Cables solid core speaker cables.
Great bang for the buck.
