I don't know your exact situation, but when I replaced the stock cords on my Quad 63s, it made a very nice difference. The AC is used to power the stators; I would guess it should make a larger difference on the built-in amps on your speakers.
How about this: Get accustomed to listening to only one channel of your stereo (say, right channel) then move the left mono amp power cord to the right Von Schweikert speaker and listen again. IF the PC reaches, you've just tested your idea at no extra cost.
Good Luck!
