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..

so everything that runs on electric in your home give out interference when its plugged in the wall out


Mainly products like solar inverters and SMP supplies (Switch Mode Power supplies), go back a few years and we didn’t have these SMP’s or Solar Inverters in the house, and back then things seem to be far more consistent in sound from day to day.
Today your system sounds great, tomorrow not so good? you put it down to yourself not being "in the mood", but you "were" otherwise you wouldn’t have turned it on.

Just turn off all your breakers except for audio and then listen...DUH
This exactly what I do when I want to listen seriously and the missus is out, takes a few seconds, but many here don’t have dedicated audio lines to do that with.

I do run all my system components through power conditions/filters for protection from transient spikes. No hums, no electrical noise at all.
I have not yet seen a good power conditioner/filter that doesn’t detract from explosive transients compared to when a power/amp is plugged direct into mains, but they are great for source equipment. I use my own using isolation transformers and expensive Siemens large block filtering brick sized cans that are used in medical theater equipment, one for each source piece, that way they have some isolation from each other as well.

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.
I don’t know how that is possible, as my system has a dedicated fuse line I installed myself, but they all still connect to the same live/neutral and earth before the mains fuse/s, and there’s no way mains fuses isolate each line for this.


Georgehifi, it may be measurable but that does not mean it is a problem.
Yes it is, just try it, it’s not going to cost you anything.


georgehifi, please list your system from first power cord through to speakers, preferably with images. Thank you!
I have 3 systems Doug, if you search you see that one is very substantial.

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.

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.

Try it you’ll be a believer

What about LED lighting? Must we listen in the dark?
Light a candle!

Whatever injects noise back into your mains.

TURN THEM OFF!!! even the TV
Then threaten your neighbors to do the same, I’m sure they’ll understand.
Ever wondered WHY your system sounds great sometimes , then not so on other times???
