What are your experiences with upgrading power cords on KEF LS50 wireless?

arafiq, I appreciate the feedback. Thank you. 
rodman99999, thank you again and I will certainly PM if I decide to entertain your gracious offer. 
docknow, thank you very much for the lengthy write up on your experience. I greatly appreciate everyone’s input but it certainly helps that extra little bit when owners of the LS50 wireless, like you and arafiq for instance, can discuss trying a particular pair of power cables and the subsequent changes they made to the overall sound. Also, I’m with tvad on wanting to know what differences you hear with the AQ and Shunyata cables. No one here will be disappointed if you get bored one day and decide to harvest them out of storage. Hahaha. Thanks again for your feedback on this and perhaps we will have a few more owners chime in as well. Take care. 

I upgraded to Audioquest and it made zero difference. Only benefit is aesthetics.  Otherwise, expensive power cables are a gimmick, don’t waste your money.  

helloitsben, I appreciate the feedback. Did you try the Audioquest cables with the LS50 wireless speakers or are you speaking in general terms based on your experiences with other gear?

JPS labs power cords might have something at a price sensible for the ls50

Indyvw, I bought and used with KEF LS50W’s (first gen, not the new ones).  Think about it this way, why would KEF provide cables that would make their system sound suboptimal?I’m fully convinced the audio industry is set up to capitalize on FOMO, in this case it’s fidelity. I kept them for their looks, I had guests coming over all the time and wanted to impress people.  

Also as a reference point (pre covid), I attended a high end audio show in Chicago. I sat in an hour long demo where they started with entry level cables and interconnects and eventually went up to $40K worth of Nordost.  Zero difference in sound.  
If you’re searching for better sound (in the case of KEF LS50W’s) here are my real world suggestions:

1) start with feeding them quality music via the analog inputs. Again do not get hung up on the cables, they don’t do anything.  
2) add a good, musical subwoofer and dial it in properly.  
3) Augment the room acoustics (add some rugs, books, paintings, couch, etc.).
