Power Cords

You can DIY by going to Parts Connexion http://www.partsconnexion.com They have a great selection of wire or even a finished product that is inexpensive. I have found this a great way to really understand whats happening with my sound and its fun to tweek.

the difference with pc's is profound... just as important as ic's and speaker cables imo(even on solid state gear). would suggest audtioning pc's with all your gear in your system (there is a culmative effect)

i have had really good experience with audience pc's and have not moved away from them over the last 18 months ( tried shunyata, xlo, wireworld, and a couple others)..

I used a Shunyata python on the Manley 250's. I also used harmonix. I never heard much of an improvement on the overall sound compared to the stock cord. Minor subtleties if your trying to hear something.

Try DCCA powercords,this will teach you what power
cords can do to your music, and your amp.

I think they do make a small difference, because stock power cords ARE REALLY crappy and do not provide consistent power. However, to those who think that it is the biggest upgrade in your system well that is simply not realistic or possible. A good power cord with hospital grade plugs will provide all the additional benefit you are going to get. In the case of an amp, it will provide slightly more power to the amp which allows you to reduce to the volume for the same sound pressure which allows the amp to be more effecient and sound better
