Replacing generic RECEPTACLES

"Why stop with the receptacles?  Why not run $1000/ft power cable from the outlet all the way back to the breaker box?  Then pay the power company to continue the run back to the distribution grid, and ultimately a dedicated line all the way back to the power generating station."

" To the power station?" That's crazy!  

If upgraded power cords and receptacles make a difference then, of course, continuing the upgrade through the walls and to the breaker makes just as much sense.  But continuing beyond that (to the power station) is just too expensive.  Instead, to really squeeze that last remaining bit of audible performance (and bragging rights) out of your system, get a  Multiquip WhisperWatt Super-Silent Diesel Generator instead.  It is on sale now for $51,000 and a steal considering what a dramatic improvement in transparency, sound stage and clarity it will make. 

I think it should be mentioned that the electrician runs both dedicated lines to the same leg (phase) at the service panel. Then your entire system will be wired to the same phase.

"Makes an audible difference" someone posted, no it doesn't . It can't , there is no logical reason for an outlet to upgrade sound…same goes for power cables…electrons are still flowing at the same speed…..

You have hundreds of fat of copper in your home and you think changing the last three feet of that is going to make a difference at what comes out of your speakers….yea, ok
