Donny: Many thanks for providing the link. It appears that Gigcables.com's 'multi-channel speaker snake' (2 channel version) with 1/4" connectors: model #SPK2-20'at $69 is cable stlye configuration needed:
http://www.gigcables.com/CNspeakersnakes.html

I called 'gigcables.com' and they also offer a shorter 10 foot version as well (more suitable for going from Tyros to KP-100S).

I was considering getting the cable with 'gold end' 1/4" plugs, and though gigcable.com offers that as an option, the sales guy advised me that this would offer no real advantage unless the Tyros & KP-100S input jacks were 'gold plated' as well. I believe both the Tyros or KP100S do NOT include gold plated jacks.

I had thought though, that the purpose of gold plated connectors was, in addition to offering better connectivity, that it also prevents the connector from getting corroded over time.

I'm interested to hear other people's recommendations on this. Should I go for 'the gold' or not?

Thanks. - Scott
