Could current response rate affect the sound?

[auchain]

People believe that there is an effect on sound when you change the power supply/ power cord.
But did someone ever try to change the current response rate? And what's the result?

Maybe people do not often use the term "current response rate".
Just forget it.
And here is what I'm thinking:
Someone said that the video and audio gear would perform differently when using different isolation transformers, such as toroidal transformer, R-core transformer and laminated EI transformer.
But why are there such differences? And what are the differences?
