Power Cords

I forgot to mention that my Manley 250's are plugged into a Powerwedge Ultra 116. Now how does that effect the power cord issue?

Buy high quality cord intended for industrial use, single core conductors preferably (but not necessarily). Terminate with accordingly hi industrial grade plugs.

Try out. Draw conclusions.

One conclusion you'll surely draw is that it's more expensive than the optimistic Marakanetz suggests -- but still reasonably priced!

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.
