I am running Gutwire B-16s on my RELs and think it makes a difference. Haven't done double blind tests as they are hard for one person to set up.

i did an A/B with my velodyn dd12 using a PS Audio AC-10 against stock. purchased AC-10's and AC-5's for almost all of my gear so i decided to try one on the sub. was very happy with the results on my other components so i assumed the same would hold true for the sub.
one thing that should be noted is that my sub's volume/output is set to 15 on a scale of 100. i only use it as a "slight enhancer" for way down low.
i noticed no difference at all so i decided against the expense. maybe if my sub was being used/pushed more, the results would have been different?. plus my system is not that high end or revealing. a better system might have shown more of an improvement?.
btw...i do have a dedicated lines and porter ports so my AC supply is decent to begin with
just my experience.
I found this to be the oddest surprise in all my years of experimentation in audio. My speakers are Vandersteen 5A's which have powered subs...the upper range coming directly from my Ayre amp. When I changed the power cord on the internal Vandersteen amps, the whole sonic picture was improved...not only the lows. The speaker as a whole became cleaner, clearer, greater depth and width, etc.
Power cords can make a HUGE difference on powered sub-woofers (just as they do for other components).
I've used (used) SR AC Master Couplers with dramatic effect. If you've got the dosh I'd audition a Tesla T3. Among the many benifits, expect enhanced air and layering in the mid-range.
Try and listen before you buy, always a good idea when cables are in question.
