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

Some design features of a power cord like effective shielding provides the same potential benefit in all cases, but the actual results can still vary case by case depending on the specific setup and whether that shielding is needed or how bad the problem is.

BTW, I have found that effective shielding in power cables specifically designed for line level gear can make a difference in DACs and pre-amps. They (Pangea) did in my case.

Others may be more designed for more power amp applications with a focus on current delivery. How effective that is case by case also will vary depending. Some amps may benefit, some not.

I do not have experience with the ls50 actives specifically, but were it me I would most consider trying power cords that feature highly effective shielding with active speakers in general.

I do have passive ls50s and I use the Pangea power cords designed for line level applications with both my pre-amp and DAC. The results are spectatular with ls50s specifically. Have never tried stock cords there so can’t say how much difference there might be but I did hear a clear improvement in detail soundstage and imaging when I first applied the Pangea cords with other speakers I run concurrently off the same system (Ohm Walsh).   Also at the time with Dynaudio Contour 1.3mkII, which the ls50s (plus sub) replaced.

THe down side of the Pangea cords is their weight and bulk....it is not easy to get them to stay plugged into the gear initially.

My DAC is mhdt Constantine and pre-amp is Audio Research sp16.

I have replaced the power cables on my KEF LS50 wireless speakers and evaluated the change. I have to run off to several Zooms for work, but will report back tonight or tomorrow night.

As far as I can tell, I am the only one on this thread to have actually performed the experiment. Everyone else here is speculating.

They speak about YOUR speakers...

I appreciate your input mapman. Definitely something I’ll consider in my search. I appreciate the link as well oldhvymech. Thank you. 
I’ll be looking forward to hearing your thoughts docknow.  Your input is much appreciated sir.  

When I first bought my KEF LS50 wireless three years ago, I had a couple of Cerious Technology power cords lying around. I put them on the LS50s and didn't notice any meaningful difference ... if anything I thought the sound was a bit less open (but honestly, that could have been me straining to find any differences). I put the stock cables back and this is how they've been used since then.

As an aside, I recently bought a power cord from Audio Envy and swapped my Cerious Technology PC on another amp ... the AE power cord seems to add a level of refinement (more cohesive, less sparkle) over the Cerious. I only have one Audio Envy PC so not possible to use it with the LS50Ws. AE cables are very affordable and they offer a 45-day trial. The best way to find out is to order some and try them for yourself.
