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..

An AM radio station is full of noise to begin with ,
I came across something  a bit different Synergistic research sells 
their speaker clarifiers and found a slight improvement filtering noise , at a audio get together I heard a much more elaborate Version which was on U.S audio mart ,made with Jupiter capacitors,and Top Mundorf Ultra resistors ,i bought a pair 
and they really filter the HF noise much better . I don’t know how they work but they do a nice Job.

If I turn off the inverter for my solar panels it costs the electricity that the panels would be producing.

Most do serious listening at night for a start so turn it off.
And what if in the day you turn it off for a couple of hours to listen, it won’t break the bank.
As here in Au now, we get a pittance (rebate) back these days from the electricity companies, compared to what we used to get years ago feeding the solar power back into the grid.

All it’s good for these day is charging a wall or car battery, and that battery technology need some serious advancing for house or cars, as it’s $8k for the car lasts 8years and then is one of the most polluting products to make on the earth, and to dispose of.

If you live in a practical world this is insane, and I suspect trolly, advice

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.
