Why not try it yourself.
You will read a lot of different opinions, yes it’s worth it, no it’s not, LoRad is good, LoRad is bad.
I doubt you will find an overall vote winner on anything.
I use screened cable because I come from an industry were screened cable was normal, it’s a hangover from that.
I have used LoRad, I still have some, but I replaced the main cables with a braided type because I wanted to actually connect the screen to earth only at the power input end.
Questin is, does a domestic installation need screened cable? probably not, especially considering the very low currents involved & worth noting that Naim cables are not screened.
Final point is your house earth supply, I read that some homes in Sweden don’t have earthed power outlet sockets in some rooms. If that is the case with your hifi power, a screen will not be effective anyway as it has to be connected to earth at the power input end.
