i noticed very little when i upgraded my first PC. it was only after upgrading all 4 that the "wow moment" arrived.
connected the first one (PS Audio AC-10)from the 20a dedicated line too my quintet. i noticed a bit of bass extension but that was about it. got another PSA AC-10 for my integrated amp then 2 PSA AC-5's for my transport/dac.
things really came together after that.
i would guess the line from your outlet should be first but in the end....you should go all in and upgrade them all.
