Can POWER CORDS really make that big a difference?


Can a power cord really make an audible difference in a system? I have heard it does, but I have not spent the money to upgrade yet. Any suggestions would be appreciated! I was looking at NBS cords. I am relatively new to the hi-end game so I am trying to draw on your knowledge. Thanks for your time.

If your considering power cords, you absolutely owe it to your self to try either the HSR-A(II) from TG Audio. I have not heard the HSR Silver, but have one on order for audition, and have heard nothing but rave comments on it.
Except in some very pathologic conditions, you won't hear a difference between stock and kilobuck power cords, or any PC inbetween for that matter. That's if you listen just using your ears, however. People can "hear" all sorts of amazing things when they listen with their eyes and wallets. Not completely a bad thing if it enhances your overall musical experience, but I'd rather put my money where it affects the sound.
Hearhere please clarify: Does the pathological condition you mention refer to:
A: The system ?
B: The listener ?

I humbly suggest, that it refers to both, if you don't hear any difference in powercables at all. Cheers,
