Congratulations, Nrchy. Enjoy your new home. Whether the listening room should be your biggest priority now is an interesting question. Perhaps so. Depends on how much of a problem it is. Obviously, you failed to make your purchase contingent upon inspection and approval by a qualified audio engineer. ;-)
In answer to your original question, my cd player was the most expensive component, though not by a lot because I got a really good deal on a demo, after I already owned the speakers (which when I bought them were the most I had spent on anything). Quite a bit higher retail price than my speakers, though. I would pay more for the speakers if I had to, but am happy with what I have and have put more money into secondary systems.
