I get more bang for the buck on my digital components (player and DAC), but it will depend upon your equipment and how good or bad your power supply is. One of my amps (with a tiny little power supply) is very impartial as to what cord powers it and the other amp which has a very heavy external power supply is effected more by PC's (you think that it would be the other way around). If you are starting out with one upgraded cord, move it around and see what sounds best.
