I'd like to call myself an audiophile and I have a hard time believing that power cords make a difference. Just to set the record straight - you have hundreds of thousands of feet of non-audiophile-quality cable running from the power station to your house, with all kinds of spikes, interferences, poor insulation, etc; then you attach a 3-foot piece oif copper wire to the wall outlet and voila - the sound is transformed.
PS - I do hope your power cord been cryogenically frozen! Cause if not - you are in deep s@#t, amigo!
