Do powercords make a difference in sound?

Rwwear, you just cracked me up.

Throw a really attractive lure into the depths and lets see what we can catch. The joys of trolling. Seriously, if this a legitimate topic of interest, consult the archives of this forum and other sites. This subject has been covered, debated, and fought over at enormous lengths.

This was one attempt at summarizing what one person heard when trying to answer the question you ask.

Your not a dealer, are you?

No, don't even think about it!!

Looking at the 3 other threads you have started, it appears you still are sorting out what you need for the major components. I'd stay the course if I were you, and revisit after-market power cords down the track.

My short answer is - yes.
