What was the first power cable that you noticed a difference in the sound?

Have to say that it wasn’t even an expensive cable that made a notable difference in my system. The first one wasn’t exactly an improvement, which was a Pangea MkII. But it still wasn’t one very much more expensive after that one that made a serous improvement, either.

For me, just a well made aftermarket cord with decently fat gauge, quality shielding and that is well terminated. But to that, nothing made as big a difference after some better “cheap” cords than introducing a Chang Lightspeed power bar. Better yet, separating digital front end with a separate power bar from the one used for the preamp and power amp.

@hickamore It definitely made a positive improvement compared to using only one power bar for my setup. I had purchased the Chang Lightspeed with the intent to upgrade from my original Furman. I tried bringing everything over to my newly acquired power bar, which did make a nice difference. But then I’d remembered other threads where this was mentioned and put just my digital components on the Furman. Everything was even better.
