What Power Cords for Rel S510 Subs?

I’m considering a pair of Rel S510s to go with my Diablo 300 and B&W 802 D2’s. I’ve invested quite a bit in cabling: Audioquest Dragon for my amp, Hurricanes for my source equipment, and Nordost Valhalla 2 for my speaker wire. I can clearly hear the difference between a Hurricane and a Dragon cord when powering my amp. The Dragon puts space and air around vocals and instruments with front to back depth.

There is no way I can afford anything better than two 3m Hurricanes for the Rel S510’s but my question is, how much do power cords matter for subs? Sadly for my wallet, I’ve found that higher grade cords do make a considerable difference for all my other components, verified through blind tests. Not as much as speaker cables, but still a big difference.

I also have a Innuos network isolation switch and also an Innuos USB reclocker, to support my Innuos Zenith Mk 3 streamer.

Does power cord quality matter less with subs than with everything else?

For the record I’ve seen other threads on this subject, with what seems to be consensus that power cords don’t matter with subs, but I was hoping others who, like me, appreciate the difference a top tier power cord can make, can comment on whether there truly is no benefit to using one when it comes to subs. Has anyone compared a Hurricane grade (or better) cord with a stock cord, connected to a high end sub?



Spend some money on speaker cables, interconnects, amp power cables and if you really want to push it, upgrade the rca/XLR cable for the subwoofer. But, spending on the power cable for a subwoofer is just stupid. You realize that you are talking about a bass driver with crossover set to ~50 hz and below in most cases right?


Oh know you dare to suggest perhaps common sense… You are now a troll !  How silly is that ? Simple Minds isn’t just a rock band. Lol 



I know a lot of people do not have a brick and mortar shop that lends out cables. This is the best way to try cables and equipment out at home. Also, I will tell you it can take a few hours or even a day or two for cables including power cables. I am not saying you do not hear a difference right away because you should. I call it loading up the cable or letting it balance out or settle in. Interconnects and speaker cables need time because of the lower voltage and I believe it needs to become consistent otherwise it’s like an empty water hose or line that needs to get the air out. Power cords make a difference the next day because the caps in the components need to do the same. Charge up and level out. The first time I noticed what a difference a power cable makes is when I replaced my stock PC on my surround receiver with a Nordost Blue Heaven. It really made a difference. Plus, some of these receivers have 9-13 amplifiers. That’s a lot of power not to mention all the other things in the same box. I say go with a 14 ga power cord so your not starving that equipment. Try it. Take your nice power card from one of your other sources like a phono stage or CD player and put it on your surround system. The next day after you charge up all of the moss caps you will understand. I hope this helps. 

@1971gto455ho , I have known a thing or two about this forum (common sense:rare, Troll Accusations: Frequent). It is the reason that I post here rarely. Generally, I just like to look at some threads and have a laugh. 

I have a pair of S/510s, been using the stock power cords for a while.  I replaced them with an older set of Pangea cords, that I wasn't using, so far I haven't noticed any difference. I have no desire to try different cords, I am fine with the subs as is.
