Another thought strikes me; is it possible, Liguy, that you have been comparing/using power cords which are somewhat similar in characteristics? i.e. Aftermarket 14 total gauge with stranded conductors, vs. your 12 total Ga. with stranded conductors?
The reason I ask is that if the power cords you have been comparing have similar characteristics, then it is very likely that you would have a difficult time hearing differences between them. I can see a situation in which you replaced a stock power cord with a Home Depot DIY and found little difference. However, I would submit that this is not the best test of power cords, and that there are many more options available. i.e. A PC with 9 or 10 tot. Ga., or one with silver OFC conductors, etc. You would perhaps find it interesting to try a Wireworld lower end PC with silver coated prongs on the plug.
Maybe you have compared a wide variety of PCs but if not, then this is perhaps a legitimate reason why you are not hearing differences! I have conducted comparisons between PCs which sounded very similar and they were in fact similar in construction/design. That may be part of the answer to our disagreement. :)
