@craigert, being familiar with Ieales’ posts I can vouch for the accuracy of analyses he provides. Also, given the equipment in your system that you’ve listed in another thread, namely:
... it seems safe to assume that a 15 amp circuit and 14 gauge wiring of reasonable length (e.g. 50 or 75 feet or so) would be suitable for powering your equipment.
Of course installing a 20 amp circuit can’t hurt, and conceivably could provide added flexibility in the future. I would be more concerned about the drop of a volt or two or three that would occur due to the resistance of that wiring (depending on the current drawn by the components as well as the length of the wires) if a tube amp having unregulated filament (as well as high voltage) supplies were involved. And there are some very high powered solid state amplifiers which can require a separate 20 amp circuit even for each of two monoblocks, but those are big, heavy monsters which typically are at the extreme upper end of the price spectrum. Different animals altogether.
Regarding the possibility of adverse sonic effects from GFCI or AFCI/GFCI outlets, I have no particular knowledge. FWIW, though, my instinct would be to doubt that there would be any adverse effects. For one thing, if significant voltage was being dropped in their contacts they would be heating up significantly.
