@a_shah -- your post's style seems inspired by Gertrude Stein. Viz., "We are able to notice that each one in a way carried a bundle, they were not a trouble to them nor were they all bundles as some of them were chickens some of them pheasants some of them sheep and some of them bundles, they were not a trouble to them and then indeed we learned that it was the principal recreation and they were so arranged that they were not given away, and to-day they were given away."

I do have a pair of Rel S510 and other 
Rels in the past and cannot recall 
hearing any difference with upgraded 
power cords.
I think it has to with class d amplification.
 I am currently using Pangea power cords
with my Rels.

 $$$ owerades cables do do nothing....And for a sub even more so, if there was any interference. it would be at the high end and well you are talking about a sub,,,,If your sub turns on your good

I own a pair of REL Gibraltar 2's.  These have 450W AB power amplification and they do and have reacted to different power cords.  I have had Cullen cables (decent!) high end Synergistic Research (better), Audience (OK) and finally have found a very reasonably priced "Pro Audio" pc made by a Swedish company.... Vovox Excelsus. (best) at $400. for a six foot cable.  A bargain by audiophile standards.  Changing power cords, atleast in my rig, really defined and helped me understand bass bloat and overhang.  I can now hear true taunt bass, actual notes not some boomy representation of bass....get rid of the overhang and the micro details in the mids and HF are more clearly defined, so it really cleans up the entire presentation.   YMMV.
