Can flexible power cables sound good?

Signal Cable has a good rap for good product and high value. That is where I would look first.

I have a Signal Cable on my power amp and honestly can't tell the difference between it and the stock cord.  Maybe I just don't have the hearing for it anymore or maybe my system isn't resolving enough.  Who knows? 
It looks better than the stock cord though.  
I have upgraded all my stock cords with after market boutique cords and really don't think it has made any difference but for peace of mind It makes me feel better knowing I have a better(?) quality cable hooked to my gear.
Maybe some day for shits and grins I'll replace all them with stock cables and see if I notice a change in the sound.

Power cords can be hit or miss case by case and I do not believe it need cost a fortune to design and build a very good one.

I use stock cords on my Bel Canto Ref1000m power amps. These are Class D and very efficient.

I do use Pangea power cords on my Audio Research sp16 preamp and mhdt Constantine DAC. I did hear a clear difference I would attribute mainly to shielding and noise reduction there....better detail and less haze. Nice upgrade!


The only problem with the Pangea is their weight. I have a lot of trouble keeping the plug seated in the device properly, especially the ARC. One false move and they lose contact.


Would like to fix that someday. Signal Cable is likely what I would try if I were to buy new.

Running a couple/various PS regenerators for past two decades..
Have PS AC12 cord–balanced warmish sound with enough detail/resolution that’s good value for the money, yup they’re rather stiff.
Shunyata HC/XC range are better—cleaner, more refined, better resolution though for more money, using their Sigma on one P20.
Ime, into the P20 (or any other power distributor blocks/cond. for that matter), only by using High Current delivery types you’ll tapped on their true potential—usually thick girth wise and mostly inflexible.
But so long as there’s 4 inches clearance from rear of your P20 outlets, the Shunyata should be fine (fairly flexible beyond that).

My Signal Cable power cord wants to droop a little in the back of my Jolida Fusion 3502P power amp.  Fortunately it sits so close to the floor that I can prop it up to a level position.  It seems like the IEC end of some cords are loose for some reason.  This is not the first time I've had this problem with a piece of equipment and an after market power cord.
