It can work both ways. I have auditioned power cords that actually degraded the sound of my system. I have an SET based system that is at the bottem of the of the price range when compared to most of the other posters systems at this forum. On my SET amplifier alone power cords (so far) have made very little difference as to the sound of the system. But, on the front end components and also on a spare amplifier that I also use they make a world of difference (not always good). Like any other component I would suggest that you try ones in your price range and see if you like them. I purchase power cords used at this site and then resell them if they do not work out. I have also tried some new with a 30 day return policy as well and it just ended up costing me shipping both ways. Right now I have two new power cords on order that are a bit expensive for my budget and that I have not auditioned. I have however discussed the cords in depth with other users that also have similar systems to my own. These are users that have also had similar experiences with mutualy owned/auditioned (we have both tried it) cable in their systems. These discussions for the most part were coducted outside of the forums, but some of the information that I required came from the forums as well. In other words, you came to the right place. There are quality cords that may make a difference to you available for as little as $60 new. Most of the stock cords that I received with my equipment (namely a CAL player and a Bel Canto DAC) are not even as good as the one that was supplied with our computer), yes, I A/B'd them. I have a Stealth HAC power cord that is too bright for me when used on my digital equipment, but that sounds great on my solid state amp and a Harmonic Tech cord that is just the opposite. You really have to try them and see for yourself.
