Do you personally recognize the sonic impact of bad electricity in your own playback?
no, not in the sense that i assume you mean it.  instead i have my own beef with bad electricity, which i suspect is different from yours.

approximately half of all gear i own has at times made weird noises due to interferences of sorts.  some of that gear was from reputable companies like JBL ( active monitors ) which you would have hoped would be able to avoid issues like this.


apparently their thinking is that if it only manifests itself maybe 0.1% of the time it's not a problem.  but if it can have dramatic effect in that 0.1% of the time then it must have some sort of effect the rest of the time too - i simply do not recognize it when it isn't dramatic.

Do you have any realistic ways to deal with bad electricity



well i always try to: 


physically and logically shorten the analog signal path


have every connector link balanced and shielded


have every component in the chain use only power supplies with 3 prong power cords and have them all grounded to the same circuit with decently thick cables like 12 gauge


of course that can only enable properly designed gear to work properly.  if the gear isn't designed right nothing will help.

were able to accomplish better sonic results?
the only time i was able to make a difference is in my car audio setup.  by playing around with different grounding configurations, cable lengths and gauges i was able to reduce alternator whine an order of magnitude.  at the end of the day it was still there - i only managed to get it down to tolerable level.



as far as effects on sound no.  i do not perceive changes in sound itself depending on power issues.  i can only perceive the power issues directly when they produce sound where there should be silence.

The most important: did you personally experimented (or know somebody) who was able to “properly” design components “which are able to tolerate garbage power”?
no.  i have no knowledge in that area.

I know a few designers who claim that they design power supplies that are immune from bad electricity. I owned some of their components and I can testify that they have no idea what they are talks about in context of electricity influence to sound. So, I am VERY suspicion when people talk about “properly designed components which are able to tolerate garbage power”. Usually it indicates superficial understanding and experiencing of the electricity sonic influence.

most people tend to over-estimate their abilities, so there is no surprise there.


although it is also possible you're describing a different problem from the one they are trying to solve.
