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

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.

you get your thread deleted for mentioning a manufacturer? thats outrageous. are we supposed to speak in hand signals or toe taps under the ground, anagrams???

I see a number of threads which are of a subject that I have a great interest in and when I click on it it has been deleted. I always wonder if a manufacturer has complained because their product came off badly. But then everybody's experience is different and some people might say hold on there I had a great experience with it.

Without being A/B demo'd the Cables in use with the Power Amp, it will be impossible to tell what has occurred through Cable Exchanges. 

A very good resolving system can when being subjected Cable Exchanges have very subtle changes discrrned between Cables in use. 

How the Subtle Change is assessed for an improved  or worse impact on the sound being produced is not always agreeable between those at  Demo'. 

I have heard Cables of all types as exchange cables, and know some are a good addition and some are not. 

When a group are assessing my down vote can easily be seen as another's up vote.
