Build your own with components from Cable Co or a similar source. You can encase the cable in white sheathing from Amazon like I did. Use shrink tubing on the ends where the sheathing and cable attach to the plugs.
Power Cable in White
I purchase some Big Cat 14 awg cables in white for my powered speakers but I can’t get them to lay flat, I guess because they are fairly inexpensive. I just can not get the bends out. You folks know all the cable companies out there, can someone recommend a decent power cable in white, for a reasonable price, that will lay nicely for me? Thanks!
