I got my Stan Warren DIY T1 cables

and they sound great. Though I paid someone to make them for me, Stan did give me instructions on how to make them. Using Berktek T1 cables, you must first remove the outer jacket, then take the two conductors and twist them with a third, then shrink wrap and terminate. That's it.

I got both ICs and speaker wire and they sound better in every way than anything I've used before, which admittedly isn't a large variety (MIT 5 and MIT 3 speaker cable, Markertek Canare ICs, DH Labs BL-1 ICs). Though I haven't compared them to the popular DIY Cat5s, Stan used to be proponent of the Cat 5s and has since formed a strong preference for the T1s.
