Great choice of speaker with the Totem Forests! Yes, power cords do make a HUGE difference, especially with sources. Perhaps you should consider upgrading power cords on your other equipment as well. I, personally, would not change the atlas speaker cables for silver ones (for the tweeters). Atlas makes a good product, and copper works very well with the Arcam equipment you have....but you can certainly give it a try and report back. As I mentioned in my previous post, I really like your choice of interconnect as well; the Navigator All-Cu's are smooth!
