Do powercords make a difference in sound?

I have 3 Transparent ref. powerlink's mm2, and short answer...yes. The source and pre-amp had HUGE improvements in dynamics. Improvements on the amp was VERY disappointing, it did remove some haze and improve the sound a little but not sure worth it. oh well.

HAve to agree to just not say anything would be best..
but....
As has been said, this PARTICULAR 'discussion' has been aked and answered many times, along with the endless debates over whether wires do make a difference, or they are snake oil.
I will conceed to say i think decent cheap(er) wire is good, but skip the expensive stuff.
A good measure (so some say) is to spend about 10% of your equipment cost on the total wire costs.
Then you are in a middle ground, and fairy safe from madness.
Of course, there are those few maniacs who suggest spending MORE than the equipment costs on wire.
Mainly, if you can't hear a difference, why bother?

If you want to try a powercord Pangea or Shunyata make decent starter power cords.

By all accounts PCs are largely component specific. While I have tried my hand at them with various items in my stereo, they have yet to make a particularly meaningful improvement. If you pose a more specific question, people with the same electronics as you may have a PC brand/model suggestion.

Hi guys!!!
I'm still here too (Or should I say "Hearing" too).
No one wants to kick a sleeping junkyard dog so we're not going to run with this again but you've already heard good advice: dial in your components with each other first; become very familiar with what it sounds like with stock cords and then, if you want to open up a new avenue of tweaking the sound you can start playing with aftermarket powercords.
Check out all the related threads for much more "vigorous discussion" on this...because you're playing with matches at the gas station right now.
All I will say is trust your own ears and NO ONE ELSE'S opinion via these forums (on this particular topic).
Good luck and happy Lissn'n

If in doubt, try it out! These have a 30 day, money back, satisfaction guarantee: (http://www.musicdirect.com/p-9670-shunyata-venom-3-power-cable.aspx) If you can't hear a difference, between them and your stock cords; count your blessings! You stand to save a lot of money, on upgrades, down the road.
