Instead of recommending any particular brands, I would just offer that you divide the money up to best effect.
Spend $2k on speakers, if they are $1500 to $1800, or $2200 no big deal. But buy speakers to fit the room. Wires included in this price. Start with simple wires, this is something you can upgrade later.
Buy a separate amp and praamp, I've always found best results with separates, so glad the day I went with separates. Spend about $2k on the both. And include any cables in that price, no need to buy any exotic wires just yet, just something nice for $100.
That leaves you a grand to spend on a nice CD player! And wires, again, just something nice, no need to spend equal amounts on wires and some folks do, anything is better than the skinny throw away RCA's they put in the box.
Decent tuners can be had for a few hundred bucks, no need to go crazy here, but if you like background music a radio is nice.
And i strongly suggest buying it all used. My entire system was built from used gear, and it would have cost me 3 times as much to buy it new, you get a lot more bang for the buck used. Of course you don't get to audition your gear, or hear it in your own system before buying. But, if any of it turns out to be objectionable, just resell it and try again. Personally, with reading online reviews and knowledge gained from these forums, I've made good choices and have not had to retry very often, only once I replaced an amp I wasn't happy with, no big deal really, considering the money I've saved.
