Really bad sounding power cables ?


Hi Everyone,
So out of curiosity, are there any power cables, including DIY attempts, you felt sounded really horrible?

For instance, GrannyRing has stated that he doesn't like shielded cables. Anyone else have negative stories they'd care to share? I'm particularly interested in an inexpensive, horrible sounding power cable to try in my rig, to see if I can hear any difference at all.


Best,

I hate that horrible sucking sound coming for my wallet when a big waste of money is lurking around. 
Shunyata Sidewinder Helix CX12 gets my vote. First off they are rigid as rebar. I have an old Hydra 2 at home on loan with three Sidewinders, one being the one you have to use to plug into the wall outlet as it has a 20A IEC socket which makes no sense. Anyway these cords are lifeless and the Supra distribution block I picked up destroys this older Hydra; or I don’t know as I have to use their damn cord to start with so not sure if the Hydra is decent or not. The Hydra with its cords sucked the life out of my digital gear... only used it for CDP/DAC and streamer.

Tried the the other two cords on their own and all my other cords are much better. No idea how old these Sidewinders are or what they cost new but not impressed with these. Can’t get over why they are so rigid. Closed in, cold sounding cords... you should try these - you’ll love em.

As far as shielded and unshielded it depends on the equipment. On digital I use Nordost Vishnu which does not have an active shield but by the geometry of the cable reduces EM/RFI. Built my own for my Bluesound Vault 2 due to the C7 connector and went with a shielded cable tied at the wall floating on the player. My WyWires and Kimbers are unshielded for analog components and feel they are more open sounding. Any cable with a twist or a braid is going reduce noise to some extent. Put an AC noise sniffer on a Kimber PC and you won’t believe how noisy this cable is but still a very nice cable so I give but maybe why I prefer other PC’s on digital.

Debate will go on and on if PC’s make a difference or not but I will say I took home a PS Audio P5 power plant and there is no guessing if this thing is working or not. I tried it with all my components plugged in and settled with everything but my amp; left the amp directly plugged into the wall. The difference between using the P5 was incredible. You want to try something that you don’t have to play games with yourself if it’s making a difference, let alone an improvement... drag home a PS Audio Power Plant. My Supra does a respectable job for the money and does not roll off or soften my digital front end but the difference with it in my system or not is not huge but it’s there; the PS Audio is just simply incredible. Maybe try one of these instead of PC’s.
I wouldn't call it a problem. I would call it an investigation born out of curiosity.


My original, god know what it went to, black power cable and this new one sound pretty much the same to me. I mean, I could be pushed into believing it was more liquid sounding, but I can't actually hear anything I'd be able to tell if blindfolded. So, then it occurred to me, since I am absolutely not going to spend more money out of curiosity, maybe the best, most affordable way to go was to try the worst possible sounding cable, because maybe it was cheap and some one would send it to me for free. :)

Sounds like a good plan, interested in hearing the outcome.

$59. shipped. Amazon. WAudio 2 meter power cord. US connector and IEC. About what you would spend to build one. Allows more current delivery into the power amp ( power amp section ). Pure copper, shielded, nothing fancy but a good for the money cable to get into, over the stock cable.
shielding is there if you must have it...(hummmm).   If you can use cables that are unshielded, they sound more open.
