How to upgrade "power cord" on turntable with wall wart?

chaster-

I just don’t get it. Maybe i’m stupid? 

Wouldn't rule it out. Which if you think about it is the crux of the problem. You have ruled it out. Why? Because you can't explain it. 

That is one very stupid reason. You may not be a stupid person. We give the benefit of the doubt. But you have picked one very stupid reason, which does not tilt the odds in your favor.

There's a serious issue here you will do well to try and understand. There is a difference between the existence of a thing and the ability to explain the existence of a thing - and the one does not rule out the other. 

Got it? No? That's a shame. Odds tilting yet again. We will try another approach. 

The Earth is round. Possibly (benefit of the doubt again) you agree. But why? Looks pretty flat to me. 

Never mind. Here's the question: The Earth being round, does it have anything to do with anyone's ability to explain why its round? 

A whole bunch of people have made the comparisons and consistently reported that power cables do indeed sound different. You claim the right to say they are nuts. Why? Please explain.

It might be worth looking into whether there's a U.S. voltage version of this - https://www.decoaudio.com/deco_audio_project_unibox_power_supply.html

Miller carbon, maybe you missed the part of my post where I said I HAVE tried different power cables on at least two of my turntables ( I might add), including one power cord that I deem to be my best, on preamps and cdps. Yet I heard no improvement on those two turntables. So you may say my experience is limited to testing 3 cords on 2 turntables but that’s my result and I am not a nihilist on power cords. 

Just spend $50 on a linear supply and the you are free to sky the limit on a power cord.
