MIT Magnum M1-M3 experiences

I am looking for opinions on the newer Magnum series MIT speaker cables. I am considering going for M3. Has anyone have any experiences with them. Does biwire makes a difference

It would be helpful if you'd also mention the amp and speakers you're using. Otherwise, it would be difficult to give you informed advice.

I am also interested! I am considering to purchase a pair of Magnum M3's. Will it give me the best sound for a pair of thiel CS6 speakers hooked up with a Krell FPB 600? Anyone experinced this set up? Need advice here pls!
