AMEN to the improvements invoked by swapping in quality power cords.
(1) Please note that some power chords (and particularly the plugs in those cords) work better than others with the particular kit you are running: it requires some swap-in/swap-out auditioning to see which works best for you.
(2) Dedicated power lines with quality hospital grade plugs (or better) will give you as much a further improvement as the new power cords themselves.
(3) Point (1) is echoed with a further quantum leap improvement for getting "right" quality speaker cables and ICs tailored to your system. To only go #(1) and #(2) on the upgrade path without invoking #(3) is a significant restriction/omission resulting in only a nominal first step in the sonic improvement journey.
