At the very least get a reasonably decent power strip: Wireworld has one with a detachable AC cord for about $40 available from Cable Company www.fatwyre.com
If you've noticed a sonic improvement, then you can move up from there. A relatively cheap Chang Lightspeed 3200 has 6 filtered outlets for about $250 (but isn't recommended for a large current hungry power amp) just for source components &/or smaller amps. There are already so many threads on the subject; I suggest you look at the archived threads, make a few choices to pick from, then experiment a bit until you find what will work well for you. There is no one absolute answer, & are probably quite a few reasonably affordable approaches.
Next thing to do: you could & likely should look into some upgrade AC cords. Again there are numerous archived threads on the subject to get you better acquainted.
And anyone who tries to tell you that none of this makes any difference has their ears completely stuffed full of silly putty.
