Woodburger, try the Goertz MI2 AlphaCore cables. They worked really well with the M250s I auditioned in my home. I believe you can buy them in lengths from AlphaCore and terminate them yourself without getting too spendy. I have owned MIT T2 and Analysis Plus 8 and ims the Goertz were far better. I have not tried them on a setup yet where they did not sound good.
I have the flat ones which are supposed to be better than the newer Boas.
