++1 for DIYing your own power cable, or purchasing one assembled. Here are a couple I am breaking in, I did the work but VH Audio will sell you the cable and do the work for $140 per cable:
Furutech bulk power cable (FP-TCS31 12awg Triple-C $45 per foot, FP-S55N 10awg "nano" $55 per foot, or best DPS 4.1 DUCC 11awg $394 per meter), Furutech FI-28 gold plated plug set $210, and the above mentioned $140 labor. You end up with the best Furutech power cables possible for $550 to $900 per 1.5 meter assembled.....or less if you do the work. Not sure they will provide the exact sound you are looking for (each cable sounds a little differently), but you can't deny the quality
