Can flexible power cables sound good?

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.

The next power cord I buy will be a nice one that also stays seated in my preamp easily with no special fuss.  The stock cord does that well.  Shouldn’t be too much to ask for I hope.

A strip of black insulating tape around the end of the connector will often ensure a tighter fit in the receptacle on the back of the unit.
