Do you run a high end power cord on your sub?

I can not agree with a few of these reviews .the Synergistic cables or power cords .I find were over priced and I had 6 power cords all $600-$1,000,Copper and Tungston system cables,They did some things very well but not no better then the competition, and I was told I had to spend an extra $400 each for the better wall wart to get the most out of the system ,I tried two,they do work ,But
What a ripoff ,for $20 worth of parts of better quality considering you have to have a dozen or so outlets for the external mess of live shielding cords which I find no better ,then the Analysis plus Solo Crystal, cardas ultra clear,
Or Shunyata ,they are every bit as good if not better without all the gimmicks and cluster Fudge of mass of cables . I am into value .
When someone had to already mark something up 10x over then offer you
A better wall wart if you give them an additional $400 retail is a a Rip off plain and simple IMO .lucky I got over 30% off from Tube U.S.A when I bought a bunch of Ayon gear so when I sold the cables did not loose much. it is your money if it works for you and don't mind the extra expense then do it. For me Value and quality beat out additional bells and whistles that the MFG is laughing all the way to the bank .

Far over 95% of all the brands who produces cables are not that special. That is why I hate all the crap what is on the market. This is the reason why people are not convinced about cables. I understand this very well.

To return to the OP. I would never go and buy an "allegedly superior" pc for a sub. However, as and when the pcs on the main components are upgraded the hand me down pcs , Transparent entry models in my case, end up with the HT and the subs. All my subs are RELs, FWIW.

I stuck a "garden hose thick" PS Audio IEC cable on my REL mostly to reward it for doing such a great job. I'm not sure it sounds better, but it feels better and that's enough for me.
