Hi WBF
So over the past year, Ive been watching all the forum talk about avoiding Switch mode power supplies in audio, in an attempt to avoid electrical noise.
Numerous examples about related to ONTs, Edge Routers/Firewalls, Ethernet Switches booth Audio Grade as well as the rest of the house.
And good results are often reported.
The Part of all this that confuses me is ... what about the rest of the SMPS in a typical house?
As I think thru my own situation.
I have USB Chargers for IPhones/Ipads, Microwave with clock, Stove with clock, Washer/Dryer, Fridge, Laptops, Fixed computer, several monitors, printer, Alarm clock, TV, 18V Tool chargers, Garage door openers, motor controls on a compressor, HVAC Low voltage control boards, Solar MIcro inverters. And probably many more.
Based on all the above, the Audio Ethernet switch, Internet ROuter and Wireless APs are simply the tip of the iceberg in terms of the pollution inside of the house and im figuring that all of the above travels quite easily across the house wiring.
Currently Im using a Torus Wall mount ISO Transformer to 'isolate' the house from the Audio system. However, I dont know how much pollution crosses that Hot / Neutral boundary and the ground and Neutral is often common anyway.
Im thinking this may be an interesting topic to discuss.
