I would spend the money on power devices that will make a difference such as PS Audio power regenerators, etc. Other than that have all the light dimmers revomed in your house. If you can not have your neighbors to agree to do the same, then have your power company run a direct line to your house from your substation. There, you will hear the difference.. of course, IMHO.
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.
