I use to own the 1.5's. I cabled them with MIT 330 interconnects and MIT 750 shotgun speaker cables. If you can swing the investment I think you'll be happy. Ultimately I would go with 330 shotgun interconnects to match the speaker cables perfect. I also used an MIT reference digital cable. These cables work great with Thiel speakers. The trick is to find them for at least 50% off retail. They can be had for even less if you play your cards right.
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.
