Still mystified by mega expensive power cords


AC travels miles from the substation, enters my house, goes into a panel, then runs to my hifi equipment. Once inside the equipment it goes through whatever wiring the manufacturer used. I don't understand how the few feet from the outlet to the back of the gear can make some of the dramatic changes claim (low end goes down another octave, deeper wider soundstage, etc). My thought is that as long as the power cord is shielded so that it's not working like an antenna, properly grounded, and of sufficient guage so that you're not loosing juice to heat, and has contacts that make a solid connection, any power cable should sound like the next, especially since the AC coming in is rectified and smoothed.

I'm not looking for flames, but for those that believe in power cables, enlighten me. Or said another way, can that $11,000 plus power cable I saw today possiblet do more than fatten the manufacturer's wallet?

@ Astock, Hi, What an excellent post you did here!, I appreciate the great read, Its post like this that make reading these forums worth while for me, Thankyou, Happy Listening.
there is an old adage "hearing is believing".

remember that short adage when auditioning equipment.
it doesn't matter what claims are made, by dealers, manufacturers, or so-called audiophiles. if you don't hear it does not matter. keep an open mind and just listen. it is also not a bad idea to corroborate what you hear lest psychological factors, biases, etc., affect your hearing such that you may be misperceiving and hearing that which is not there.

what I am saying is take advice and reviews with a grain of salt and let your experience be your guide.
I don't believe in "believing" or "not believing" in power cords : ) I listen and then decide whether something is significantly better or not. For me, in my system, the Elrod Statement Gold cords are a revelation.
My impression is this part of audio still lives in the midieval world of blind acceptance where the users don't seem willing to stand up and demand progress to at least the age of enlightenment where you have to at least show empirical principles of predictability for results in order to gain trust.
