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..

I like Miller Carbon’s comment.

I would see if new speaker set up or master set might help.

This is not snake oil (aka $200 fuses) it’s measurable.
Trouble is, a mains filter can get rid of it on your source equipment, but from my experience mains filters are detrimental for poweramps to be on them, as they introduce current limiting and series resistance.

Doesn’t cost anything, just try it, turn it all off, especially the solar inverter and have a good listen.

All the portable "AM radio test squeal" shows, is the amount of "radiated noise" imitating from any smp powered appliance in a household, and if this is through the air, imagine what is going back into the house wiring being hard coupled electrically to the said smp.

Glad I live alone in a big house. Nobody microwaving, no teenagers blow-drying, audio on a separate circuit, and the few neighbors all retire by 10 pm. Music blasts from a black background while I pee off the deck gazing out at Jupiter and no one the wiser.
