I recently tried out upgrading my power cords on various audio components I have. I really didn't expect much but was shocked to hear some very big improvements. I didn't try a variety of brands just a $199. Transparent verses the stock cord. It greatly improved the sound of cd. It made it more natural sounding and took away what I can only describe as glare. The reason for my post here is the improve gained when I put the upgraded cord on my AcousTech phono stage. This is a very good phono stage but with the upgrade the background was so much more quieter and dark I could actually hear more detail from the recording coming through. My findings caused a firestorm of debate on the "cable" forum, all I can say is give it a try if you think what I heard is something you may be interested in. I definitly heard improvements in my system and have put one of these upgraded cords on all my components that allows an upgrade. The difference was more subtle on my amp but very apparent on all source components. I feel strongly that the $199. price was easily worth the gain in sound quality I experienced. I would be interested to know if anyone else has tried this or the results you come up with when you try it.
