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.

Byron, I think of AC power as just DC power at any one moment in time. We all know that current reverses 60 times a second and has zero volts/current 120 times a second. Your amp, etc. is not at the end of the power chain but is actually at the center of it in series. Any non-linear defect in this series circut with all the starting and stopping before we even consider the changes of modulating this current with music is an arithmetical mess. Consider that each connection is not just a little resistance but also has a diode effect with current flowing better in one direction than another. And we havent even gotten to your Wi-Fi impressing it's signal onto the house wiring acting as an antenna. Mind boggling, Mike
