I have followed this thread closely and until now have not felt like saying anything. But the last post by Sp has sparked me to reply.
Over the past ten years or so I have listened to atleast 100 or more power cords in my system. Never satisfied with the results, I started building my own. At last count, probably 30 samples. Every type of wire, geometry , shielding method and terminations imagineable.
None of my final designs, with the execption of (1) are shielded. Shielding, IMO adds an audible coloration that I find quite annoying.
The question, "how can a line cord affect frequency response?"
Based on my experience, the #1 factor by far is the type of conductor material the cord is built of. Everything else is secondary. How?, the same way an interconnect does. Use conductors that restrict bandwidth and the frequency response will be adversely affected.
