Last week I attached a 15m cheapo ethernet cable from the router in the living room to my son's PC in his bedroom, so he can become a killer fortnite player!

Surprise, surprise I've spent this last week struggling to understand why my system went from being incredibly moving to become unbearable to listen to.

After a lot of head scratching I finally thought that maybe I should unplug the ethernet cable and voila back came the music.

Just to be sure I plugged it back in and again the sound became unbearable with a loss of bass, a hardening of the sound and high frequency distortion.

Anyway, enter the rabbit hole

I now find myself wondering whether replacing the routers SMPS power supply with something better may also bring some rewards.

Anyone tried this?
