The biggest improvement by far will be to replace all those crappy factory power cords. Literally anything at any price, you could throw a dart, will be a big upgrade. Don't do that however!
Instead, go and listen. Ideally bring as many home as you can and hear how they sound in your system. Not because they are system dependent but because you know what your system sounds like. Or if you go to a store then at least bring one of your crap cords along to compare. Prepare to be shocked! ANYTHING at ANY price will blow away what you are using now.
BUT here's the thing- if you really do try a lot of them you will eventually find the really good ones will blow away the rest even many times much more expensive ones! The gold standard, not because its the very best but because its been around so long and is crazy good for the money, is the Synergistic Research Master Coupler. They've been making this for well over TWENTY YEARS now and there's a reason- its that good! So good they sell used now for more than mine cost new. Not saying you can't find better. Saying you owe it to yourself to check it out.
That's by far the most important advice I can give- go and listen. Forget construction. Forget reviews. Forget everything anyone here recommends- including me. Just go and listen.
