My vote: replace the CD player and improve the room environment - forget about the cables and power cords (you've got bigger fish to fry!).
First, the CD player. You don't have to spend thousands of dollars here. There are a host of really good players for a $1,000 (Thule, Arcam, Classe - used). My recommendation, though, is that you buy a good used transport and buy an inexpensive but good DAC (Perpetual Tech, Monarchy, etc.). DAC prices are coming way down. Over the past twelve months I've compared some very expensive ones with these less expensive ones, and the difference is becoming fairly small.
Second, the room. Your room conditions suck. I know this becuase my room was fairly similar to yours. However, I've made a number of changes that have dramatically improved the sound performance. Without going into to too much detail, go to the TAS website (www.theabsolutesound.com), access "Free Articles" and read REG's article on the eight ways to improve your speaker perfomance. This is a great article and will address the host of problems you are facing in your room. After making all the changes in my room I have improved the soundstage and frequency response. It's a striking improvement.
Good luck, and enjoy the music!
