Power cable education needed


Hi everyone. I need some education on power cables. I have been reading that a good power cable is vital to a good sounding system. If that is true wouldn’t the companies the make the components include a good power cable to insure their product sounds the best that it can ? Should I evaluate the power cables in all of the components in my system?

Companies don't include power cables because: specialization.

It really is that simple. 

If you are using freebie rubber power cords then everything out there is such a big step up you cannot possibly go wrong. If you want better then buying a power cord is no different than any other component. Read the reviews, buy the one within your budget that sounds the best. Once again yes it really is that simple.

The hardest part will be to realize that not only is buying one the same as any other component, but the quality of the power cord matters just as much as the quality of the amp. 
@millercarbon,

Thank you for the advice. I’ve been reading good things about the Shunyata products along with their recommendation by ghosthouse above so I’m going to start there. Also Synergystic Research is on my list as well to check out. 
Ron -
One more suggestion. Seems like power cords by "Audio Envy" are getting a lot of positive buzz around here. I haven’t tried them but an audio-bud has them and by comparison to more expensive cords, he found them much better. There’s at least one thread about Audio Envy on A’gon. Might make some interesting reading for you.

My three rules of audio: 1) There’s always something better sounding out there. 2) You can always spend more. 3) #2 does not guarantee arrival at #1.

Good luck, have fun and hope you find something that lets you enjoy your music even more.
I can't spell Synergistic either. They are however my favorite. Not necessarily because they are the very best. But because they have been so consistently good for so many years there are a ton of them out there and so whatever your budget you can simply buy the newest/best one and be pretty much guaranteed it will sound great.  

I had until recently a combination of SR and Shunyata. Caelin Gabriel actually came and demo'd the one I have. He is based just across Puget Sound from me. Those have been replaced with M101 now, insanely better but also a lot more expensive. Oh well the last ones I had were fine for a good 20 years, these will probably be the last ones for me now.
