Power Cords


Someone help me understand the potential (if any) sonic effects of power cords. I have seen a wide range of prices for these things. Are they worth it, and what are some recommendations. I have Manley Neo Classic 250's.

Unbelievable but true the last few feet make a difference. It appears to be more than just the voltage it can deliver, the alloy used has a pronounced effect on the sonics in my system. At the risk of repeating what others have said using a particular type cord should be mated to your equipment. I like a silver based cord for the source but larger copper ones for my amps.
Good plug = $3.00(each end)
Good wire = $2.00 for entire high quality powercord.

Total parts price = $8.

Total retail price OK upto $30 using general rule of thumb.

Anything higher priced won't ever give a performance improvement.
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.
