Much as I hate to agree with Thunders....he is correct. You have three things that need work.
The CD player should be the first and most expensive. Whatever you get, you probably want to keep for a while.
I suggest a 24bit HDCD player, or a good DAC if you prefer that route. The room you describe is hell on good sound. You might want to follow leaf's recommendation for a large area rug and bookshelves or drapes or something to help with the walls. Last would be the cables. Start with ICs. I don't know your speakers. Your Pre is made by a company whose Amps are great but there are better preamps in my opinion. Rotel is a solid performer for the price.
