From your list I have had the Tel Wire and Purist Audio Dominus in my system. Today I only use Tel Wire power cords. The PAD cord I had used the Ferox shielding. It is a very nice cable but quite hefty and hard to maneuver. I found this cable sounded best on an amp, not my source components.
I was not able to do a side by side comparison of these cords, but from recollection the sound was darker using the Dominus in my system. The Tel Wire is a very neutral cable. The lack of shielding (at least in the traditional sense) had no adverse effect in my system. It is also a very flexible cord. Unfortunately the Dominus will show up used more often than a Tel Wire cord.
