[B]If power has to travel from the powerstation through countless transformers, neighborhoods, and finally through the house wiring... what difference will the last few inches make?
not to mention transformer windings and internal wiring of the unit. still, untill someone tries them they won't know if powercords will make an audible improvement to their ears/system.
there's been some semi interesting discussions on the subject at audioasylum, but i've gotten to the point where i've lost interest. if i recall correctly one group believes it's the better grip the plugs have on the outlet (makes sense to me), another the lower inductance in the design (okay, maybe, if i try real hard i can see why), and a third thinks it's just shielding (makes sense to me). a collegue built a bunch of powercords using carol cable and wattagate connectors that he claims sounds as good as most of the pcs we've tried (he's in the "it's the connection to the outlet" camp). still, in my system, power cord changes have been at times surprising (been through a handfull).
just to expand on your thought process, a speaker level signal travels through (usually) lower grade wire inside the speaker, through tiny
wires in an inductor (at the crossover), then around tiny
wires in the voice coil. still, speaker cables also make an audible difference to my ears in my system.
a line level signal travels through more inductors, a pcb trace (if your component uses them), and (once again) usually lower quality wire inside the unit itself, all of it unshielded and relatively close to a transformer (unless of course you've got an outboard unit). but here we are talking about interconnect upgrades.
before upgrading power cords i highly recomend picking up some hospital grade outlets from your local hardware store. they'll run you <$10 and will provide a much better connection with whatever you plug into them, it's a tweak i had read about on aa but waited too long to do... and it's improvements were up there with those wroght by my current cords ($450, $250, and about $50 worth of DIY based on Doc B's design).
those crazy audio guys and their crazy ideas... when will it end?
