Why does better power = better sound?


Why does improving power quality improve sound quality?

I’m not asking to start an argument about power cords or wall outlets. Please let’s not go there. I’m asking because I’m hoping to learn some technical explanations for the effects of power quality on sound quality. I think I already understand how…

1. greater current availability = greater dynamic range
2. reduction of RFI/EMI = better signal to noise ratio

…but what about these…

3. ???????? = greater perceived resolution
4. ???????? = more realistic instrument timbres
5. ???????? = more precise imaging

Are differences in resolution, instrument timbres, imaging, etc. somehow reducible to current availability and/or powerline noise? If so, HOW are they reducible?

Again, I’m hoping to get into technical specifics, not polemical generalities.

Thanks in advance.

If you accept that better quality components (power supplies, caps etc.) lead to better resolution, imaging etc., it is fair to accept that choking or polluting the power required to operate the equipment will diminish the potential. Providing clean power is just allowing equipment to operate at its full potential.

Remember you are trying to retrieve everything from your source. Less 'resistive' components all through the chain will allow that. Better quality just means less bad, since everything takes away.
