Do powercords make a difference in sound?


Do they make a difference by upgrading stock power cords in amps, ect versus aftermarket power cords? If so, can anyone advise a good bang for the buck upgrade?

There is no one who is not entitled to their own opinion, it is not something that can be "taken away" from them per se and therefore simply exists if so stated. The value of that opinion however, when scrutinized via truth and fact in hand, will vary from legitimate to ignorant, depending on the viewer's awareness to the presented facts.
To say: "there is no way to prove the hypothesis that powercords make a difference, it may or may not be true." is NOT true, as many of us on this thread have tried to make you aware and as I have specifically claimed citing verifiable evidence, several times.
The evidence is NOT debatable when blind testing (as earlier described) proves with NO doubt, that different cables result in easily discernible and often dramatic differences in sound each and every time the swap(s) is/are made...each and every time properly identified...and are repeatable with dozens/hundreds/thousands of people...100% of the time. This now constitutes FACT. Like it or not. It also confirms that your entitled opinion conflicts with the facts yet you are of course, fully entitled to have it as long as you wish. Enjoy.
PS After first receiving my Conrad Johnson monoblocs I initially set up my system and became familiar with its sound. Shortly thereafter my first order of upgrade was to have IEC receptacles installed in them, replacing the fixed stock cables attached. Swapping in my aftermarket powercords (which had been previously used in my former pair of monos) resulted in an instantly noticeable and significant improvement to the sound. This history of replacing stock powercords with aftermarket upgrades resulting in obvious performance improvements has been consistent with virtually all the components in my system over many many years. Anyone pondering this upgrade path should do one thing: TRY IT, and let your ears make the decision. Odds are you too will find the choice [to upgrade from stock] an obvious one...do it! (then defend your decision on these threads!)
Lissnr, it's not too late to collect a million dollars from Amazing Randi. No one has yet.
Rwwear, that is because it is a fraud. How many have tried to get the million?
hi rwwear:

a a blind test only does not reject the null hypothesis.

proof requires deduction, not listening.

proof requires mathematics or logic.

what you call proof is not proof of certainty or truth.

you cannot say something is true because you hear it, or because 1000 people hear it.

i don't reject what you say about blind tests and i will accept that people hear differences. i myself, own several after market line cords.

my only point is that listening does not lead to knowledge.
