I have to say Martin that you are disrespectful to Lynn and all his great writing. I hope he never reads your rude comment!

Has anyone tried this for a DIY power line conditioner?

@Rick (et al)
From the peanut gallery these debates seem endlessly unproductive.
I have a suggestion: Publish the design of the power supply that is fed by the subject power cord -- in the location where a difference is detectable -- and lets see if your critics have a meaningful analysis of how and why it is "incompetent"... and how to fix it.
Incidentally, do you think these Triad transformers are a good choice?

And chaps, is this Galo power supply competent or incompetent?

Absolutely!
And here's the soundtrack on which high-end power cord manufacturers agreed upon to be their test standard:
Then, there is no point to discuss the sound of cords and wires with us mere mortals. There is enough of members here that claim to hear those things and worse. Open a new thread with a call to fellows with supernatural hearing and enjoy the discussion.
Are my measurements disrespectful as well, to his claims? 🤣
Great designers are not always right in every claim they make.
And your wife even hears the difference in kitchen with the door closed. Where did I read that before?😆
I like those split-bobbin transformers, they should have only about 30pf between the Pri and Sec. Use the largest VA one you can fit in and afford. Larger power transformers sound better than small ones. Many people agree with this about power transformers.
You have a excellent suggestion.
I like this quote,
"The human ear/brain is a non-linear system, works completely differently than our test instruments. As a result, there are things that are easy to measure and hard to hear, and things that are easy to hear and hard to measure. This makes good audio engineering both a science and an art. My take is that a component must measure sufficiently well that you are confident you are not hearing an objective aberration, and then must also subjectively sound quite lifelike."

Has anyone here found that their power cables sound better after burn in? I have. How about you?
"Typically, a cable will go through several very definable stages of burn-in with corresponding sound qualities. Unfortunately, those changes in performance can be very radical ranging from “OK but a bit fuzzy” to downright bright and aggressive to completely opaque in a period of just 3-5 days. This causes wildly differing opinions on the performance of a product depending on when a person happens to check on the sonics and how much patience they might have to get through the roller coaster ride. Users on some forums even accuse manufactures of simply inventing burn-in as a way to trick people into keeping a product that they are not satisfied with."

Fuses should not blow (become open circuit) instantaneously. Fuses have a specified time-to-blow interval that varies with the overload rating (above rated ampacity) of the fuse. I worked for a company that made circuit protection devices and did extensive testing of this. Fuses need to provide current above rated value for short times to avoid nuisance tripping.
it's not 'disrespectful' when so much of it was 1, posted as a personal opinion and 2, the technical claims in large part, just plain wrong.
Sharpen your own critical faculties. It would serve you well.
The typical "I am light years better than you" stupid nonsense some post when NOTHING proves their point.

Doesn´t the Forum have some anti-Troll function?
It should.
Alternatively, as tombo56 suggested, Rick has an incompetently-designed power supply or a grounding issue.
Rather than pigeonhole him as delusional, perhaps y'all might make one of these threads productive for the rest of us and see if tom is right?
Encourage Rick to let us see his system and then look for the rational reason he's hearing things. I see useful troubleshooting help all over this forum.
It was in that vein that I put up the Galo PSU from TAA 1995 which took inspiration from Rick's work/opinion. Is it incompetent? Why and how could it be fixed so that power cords will behave as they should.
Of course Rick would have to participate. Rick?
