This being the case, may I assume then, that aside from the measurable quantities of voltage drop and bandwidth of the cable, nothing else will have an effect on sound quality from power delivered by a power cable, everything else unchanged? And, how difficult is it to build a power cable with the greatest possible bandwidth?
@kevn I previously described the two most important aspects that affect an amplifier, insofar as a power cord is concerned. There are other effects but there are so minimal they can be ignored. I don't think the 'greatest possible bandwidth' is all that important, since the charging time we're talking about is milliseconds rather than microseconds (so not particularly high frequencies). So the task is actually pretty easy once you understand that fact. The raw AC Voltage drop across the cord dominates the equation, so to speak.
