Dave, I'm not sure what your system is, so I will only comment on my system and experience here.
I had a TREMENDOUS upgrade going from the stock AudioPrism cord to a 20amp (female end) to 15amp male end Tg Audio SLVR! Huge upgrade to my entire system. Every component is upgraded. I would do this before adding/upgrading any other cords in your system. For me it was huge. Also, think about replacing the wall outlet to a 20amp outlet as well. I used a Acme audio 20amp cryoed - again the whole system benifits - bigtime. Better than upgrading some components here.
