I need good power cable for musical fidelity KW500


Hi everybody,
I need help, I had KW500 for 6 months now very happy but i still can't find any good match power cable to go with. I still use the factory one (actually is really good sound) I did try some cable and most recent one and most expansive one is Shunyata Python Helix still no good I don't know why(factory one is even better). When i use python ths sound much closer a bit shut in lost the soundstage but more bass which is I'm not looking for.

Current setup:
Dynaudio contour S3.4
Musical Fidelity KW500
Marantz SA11S1 SACD player
all cables are Audience au24 interconnect and speaker cable and power cord for CD player.

Today i have a chance to test the hydra 4 with python. This time is much better than just use python alone.
But i still not sure by the time i spend two python one hydra 4 price and i can get much better and more expansive PC.so which way i should go...please help me.
Get the FREAKIN TRANSPARENT MM PC already and forget the other scrap and tin ear responses...do it now!!!
Guys,

Did you let the Phythons break in? My sound stage was a bit narrow and bass was not as well integrated as I would like but a few hundred hours later...
wow!

I do have Hydra 8.
