Monstrous power cables

I just purchased a couple of the Waudio cables from Amazon that mceljo recommend earlier in this thread. I installed the on my dac/preamp and amplifier yesterday. I had paused the song from MacBook, installed the new cables, and then pressed play again. Immediately it seemed to be louder and more bright. I cannot speak for other people's systems or what a $1000 cable can do but on my system with these cables over the stock ones, I did notice a difference. 

I've been told that the primary objective in cable design is to reduce resistance.

If you can’t put a sentence together, or your post is full of typo’s, spelling and/or grammatical errors, I tend to pretty much disregard anything you’re trying to say. Especially when you’ve never even tried the equipment or component in question.

It’s always the same "blow-hards" posting in here with zero experience screaming at the top of their lungs that something doesn’t or cannot work. Usually these people don’t have a system listed. Ever notice that?

If you can’t hear a difference in power cables, great.

Save your money and buy some better equipment.

A power cord can absolutely change the sound of a component. To say otherwise just shows complete ignorance and a lack of experience on the subject.

Winner winner chicken dinner, we have grammatical perfection side stepping his panties in a knot. Honesty prevailing quite likely buying better equipment.

Question:  How many of you have done a blind test to remove confirmation bias in reference to power cables?

The reason I ask is I was comparing DAC/streamers the other day.  In the past, I’d listen to one then swap out to listen to the other.  Doing it this way I heard a difference.  But it wasn’t a swapping back and forth type of a comparison.

I finally connected the two setups I wanted to compare (PS Audio Perfectwave with Bridge II vs Lumin U1 Mini into Benchmark DAC3) at the same time using the same brand of Ethernet cables and XLR cables to my preamp so that I could feed Roon to both streamers and swap back and forth using my preamp.

When I did this, I knew which input was what and, using three tracks from three different artists, I heard a difference.  The Lumin rig offered more distinction around the instruments which made the sound stage appear both deeper and wider.  The PSA rig by comparison softened the images and blended the soundstage more.

I preferred the Lumin rig, but not by as much as I thought I would.  I really thought the newer rig would provide more of an improvement in sound since the PSA unit is probably 10+ years old.  But I did prefer the Lumin setup by a slight margin.

Then I thought I’d get my teen son involved in my testing.  I showed him how to play the tracks and how to swap them back and forth.  BTW, I had previously used a decibel meter to get the output volumes as close as possible.

On the first test track, I clearly heard the same differences.  So I knew which was the PSA rig and which was the Lumin rig.  Except I was wrong.

Surprised by this we went to test track two.  Again, I heard the same differences.  And again I was wrong.  I preferred the PSA rig on the first two blind tested tracks.

The third recording the rig I chose was the Lumin setup.

My son, sitting off to the side while performing his duties, said that on the first two tests the PSA unit offered a cleaner and more distinct sound in the higher frequencies.  I’m guessing he heard more of a difference with his 16 year old ears vs my 57 year old ones.  I didn’t ask him what he heard on the third test track.

So I’m a bit dumfounded by my experiment.  I came away from that brief test with the idea that the better sounding rig was recording dependent.  This now knocks my desire to upgrade my streaming device into a loop.  

The power cables used were different, however, and I might try this again using PC from the same manufacture.
