Casouza: Indeed, you are right, but they are called "Magic power cords". Already another ASR user told me about changing the stock PCs (he has now the Aural Symphony) with better results. Myself I tried to test the Magic cord (the one with the standard IEC used to power the ASR battery) against other aftermarket PCs (Silent Source and White Gold) and the impression is that the Magic cord is not up to the level of the other cords. They sound less relaxed than the other two cords being harder in the extreme frequency ranges. So, I'm also considering changing them. I think it's worth trying.
