cable selection, Analysis, MIT, Red Rose

I could use some suggestions as to which speaker cable to purchase. I am running Rotel's 200 watt SS amp into a pr of AudioPhysic Tempo 2's. Have Audio Research LS7 Tube preamp. Am considering Red Rose 336, MIT Terminator2's, and Oval 9's. I've heard the Oval 9's on my speakers , but different electronics--they sounded great, but that could also be due to the $6,000 tube amp they were hooked up to.
If anyone has any input I'd appreciate it, am looking to buy used so it will be difficult to try before I buy.
