Synergistic Research Euphoria HC power cord.

I disagree with Jason. But like I said, their landing library is the way to go. The only way you’ll know if the cable is a good match is to try it in your system. I would also wait until the panels are in place before making any changes at all. 

@bwguy John (in addition to Jason) has also helped me. He’s straight forward with his recommendations. If you can get both cables in to demo you will have your answer. I’ve chosen SR over a number of other major cable brands.

Shunyata Sigma is one I am interested in also.  I have Mac amps, which is why Jason recommended Synergistic Research.

What sound characteristics/improvements are you looking for and what are you using now?
