Power cables for PassLabs preamp and poweramp


I just setup my pass xp20 pre and xa30.5 class A amp, finally moved n unboxed everything after 15 months.  I been wanting 2 try some new pc I now have nordost---soundstrings---AQ----n just bought a shunyata ps 8 package----I find the venom defender does not sound good with the pass equipment.

Those r just a few of the PC I have used in the past, I have been advised 2 go with the Shunyata PC.
I would be thankful for ur input.....I also just ordered Maplewood 4" speaker plinths for my Gallo speakers
because I now have a concrete floor 4 the first time-------player is oppmodwright full mods. 
128x128henrycai
WyWires Silver Juice II
Kimber PK10 Gold 
Those are what I use and sound great on both Pass and ModWright.
I can't speak to Pass gear specifically but Cerious Technologies PC's were the ones that finally convinced me power cords make a difference. Plus they are quite affordable now that they sell direct.
