I can only say I've reterminated a number of AC-14s using Furutech AC/IEC connects and think it's well worth the (considerable) effort in terms of improved sonics. Bear in mind that there are approx. 160 individual wires to deal with inside these cables and most are very thin requiring a steady hand with the wire stripper or whatever you use to remove what's covering the wire bundles. And don't even think about it if you haven't built power cords before.
