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

I think we better can stop to make it too personal. Better focus on the things were it is about. Audio Always will be about a personal taste. We are all different with different idea's. At the end a customer can make his or her own decisions. You give a demo and people can compare it with others. I Always try to create a higher endresult compared to a competitor. This works very well for me. If a cleint thinks he or she can get a better deal elswhere I would go for that. Audio is about your own choice. Just listen and compare.....

Powercables have more influence on the overwhole sound than most people think. Just listen with your own ears!

I replace all stock cords. They are almost always too short or long. They will not bend the way I need or the ic or the plug end is too long.

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.
