Get the best from your system while listening without any cost



Turn off your solar systems inverter while seriously listening, as it puts very high frequency s***t back into your house mains wires, as does your microwave and anything with a smp (switch mode power supply) which ends up in your system, I’ve seen it on the oscilloscope.
And if the missus want to cook with the microwave, tell her to get take out delivered

Simple way to test if you don’t have a oscilloscope, is get a portable AM radio that does not mute if "off station", and tune down to around 700khz on AM and turn up the volume and go near any smp power supply and listen to it squeal it’s head off, this noise is getting injected into you home mains wiring and your system..

Most of this can be avoided by wiring your system on a separate spur connected immediately after the supplier's fuse and connecting all the house mush further down another line.
Most of us have done that.

Of course that won't protect you from your neighbour's mush coming in along the electric company's line, but the source of that is a long ways away so it will be at a much lower level.

In another thread I explored the possibility of earthing the system spur with a separate earth post.
