Which MIT cables for Thiel???

Reading many different threads over time I continue to see MIT cables mentioned a the "perferred" Thiel cable. I am still building a system and would rather use the members expertise than to shoot in the dark. My current system is Bryston B60 integrated w/ Thiel CS1.5's. Wire is Transparent the Wave 100. Still looking for a CDP, digital wire is Transparent the Link 100. Should I MIT both wires or just speakers? Need approx. 8' speaker wire, looking used $5-800. Which wire, there are so many different? Would like to warm system a little. Advice appreciated. ps, considering Cary Audio CD303/200 for CDP.
