Maybe Power cords for powered speakers?
I use transparent powerlink plus on my amp(bryston 4b-st) with a noticable improvement in bass extension.
I used a MIT z-cord on my pre/pro (Rotel rsp-976) with very little change, maybe a little blacker.
These are both relatively inexpensive cords, especially if bought used.
I imagine that Powercords for powered speakers would/could make an improvement.
