recommend me good power cable , thanks

Your comment about your comparison of a high end Nordost PC to your Black Sand Violet Z1 PC is exactly why I've stuck with Black Sand PC's while the rest of my system has evolved. I've gone from just OK IC's and SC's to better, and now I've got Kubala Emotion IC's and Kubala Expression SC's. All the while my Black Sand Mark V's and Violet Z1's have withstood the test of allowing the better IC's and and SC's to stand out.

I have done a lot of experimenting with power cords. Make your own. Use either Furutech F1 series connectors or Oyeida 046 series with Accrolink cable and you will be very pleased. If you decide to go with a factory cord, do not be predisposed by any suggestion...try it in your own system. Even with the same brand of cable, your amp, and preamp may like different cables. Experiment.

I've been very pleased with the TelWire pc on my cdp.
As mentioned above, synergy is the name of the game.
I've read great reviews of pc's from Agon members whose opinions and preferences I respect.
They rave about a pc, I purchase that pc and put it in my system and it sounds nothing like I was hoping it would sound like.
ALWAYS-if possible-try before you buy.
Good Luck!

When you do find all your preffs in one cable, do let us know which one it is/was.

I've yet to find one cable which supplies every listed item... and only via a combination of cords did I get those items into the whle of my rig... and some are suited for tubes better than they are suited for SS. Some go with anything at all, and some are component dependant.... as was said already.

I do prefer combining different companies cables though.

I have to agree with Blindjim...Just like speakers and equipment..No different..Whats good for one may not be good for another..Its all about your ears and System Synergy......
