I have found that an upgrade in power cords improved my pair of REL T7i subwoofers. I did not go crazy I simply upgraded to a 10awg 99.99% pure OFC copper using a good IEC and AC plug, all cryo treated.
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?
