New expensive power cord for amp and no change in sound?


I bought new an expensive(for me) well known and reviewed power cord for my very good amp and plugged it directly onto the wall socket. After a couple of weeks of daily use I hear no change in the sound quality from a $500 cord. I don’t want to name it for fear of getting my thread deleted. You would know it or at least be aware of the company. Did I throw away several thousand dollars? Before I get the snake oil answer I want to let you know that I bought an upgraded cord for my pre as suggested by the pre’s manufacturer and am pleased with the results.

I guess for full disclosure the amp’s manufacturer said don’t bother. But I had had good luck with the pre so I thought it would be a good idea.

Anybody else have this happen to them?

*S*  I'm in no particular hurry to enter into the "Oil or No?" fray today...
For that matter, no real plans other than those already in hand or in my face...*L*

Sometimes, ignorance is bliss....and the playlists and applied volume can keep me tentatively 'comfortably numb"....

(....I have given my amp..well, 'amps', since there's 6...a heavier pc that's been lurking in storage, and it's longer than the typicals...)

No pedigree, just mo' copper...

There’s only one truth about cables/ power cords it doesn’t make difference don’t waist your money on snake 🐍 oil 

spend your money on actual components instead 

Hopefully, you can sell the expensive power cord and get most of your money back and be glad to have the cash to spend on something more beneficial. To my ears, upgraded power cords, and cables for that matter, have made a subtle but noticeable difference, certainly not a night and day improvement. I think we all hear a little differently and that doesn’t mean that others wouldn’t hear more of a difference or maybe none at all. I’ve tried out more expensive  switches in my system and I just don’t hear a difference between those and something cheap from Best Buy. Doesn’t mean that others Wouldn’t hear a difference and I don’t think it means that my system is not resolving. It’s just the way I hear it personally

I was glad not to spend the money which I would’ve done if I could hear a benefit. Folks who use their own experience to invalidate someone else’s are off base in my opinion. We all hear a little differently

It’s hard to hear the subtle difference sounds of power cords because 1 power cord changes 3~7% of whole sound (small portion). The form of different sounds might be different from your expectation and you should relax and look at whole package.

My system sounds very quiet and maybe you can pick up the sound difference easily from below video (JPS $700, Zentara $2200, WTv2 $1000, WTPC $2400).

To hear cable sounds,
1) click this 18:51 WTPC (This’ll open Youtube window).

2) In YT, make a small YT window (narrow & tall, Right half screen) to see the video screen and 2 time stamps (18:51,  4:45  in description) are in the same screen.

3) Click (18:51 WTPC) and listen 1 minute. Click (4:45JPS) and hear 1 min. And repeat to hear the sound difference. Just relax and watch the screen and listen to the vocal and sound-stage.
