Opinions please on a starter audiophile system?


I am in the process of completely revamping a long standing 2 channel stereo system consisting of older Polks, big box store sony cd / amp.
I suppose I could classified as a "newbie" to audiophile components but believe I can drastically upgrade with a desired budget of $4K.
Would love to hear opinions and thoughts on amp/cd/speaker components that fit that budget.
Have researched much, auditioned little, though trying to finally go hear, make a choice and get off the audio merry goround.
Musically we listen to a variety of stuff - jazz, folk, rock, jambands, lots of archive.org stuff. Logistically, the system will reside in the living room 14x 18 of a 9 foot ceiling'd post and beam house with open floor plan. HELP? Much thanks.

I agree with those who say the speakers should come first. If you don't like the sound of your speakers, you won't like the sound of your system, no matter how good the rest of it is.
The sound of the speakers change every time you change electronics. Those Polks will sound fine with some good electronics. Most dealers will allow you to audition electronics. He can see for himself.
The sound of the system ends with the speakers, it does not begin with the speakers. If anyone is going to start new they should begin at the beginning of the audio chain.
Dealers will allow you to audition electronics in your home before you buy. That way you can evaluate the changes in sound with known speakers and note each improvement. If anyone thinks speakers first, they should give a rational reason WHY?
Seems pretty simple to most of us, Orpheus - the speakers have by far the greatest effect on the sound of the system, along with their interaction with the room they are in. Even in these sorts of friendly arguments, I don't recall anyone trying to deny this fact. So I repeat, if you don't like the sound of your speakers, you won't like the sound of your system no matter how good the rest of the components are. If you disagree with that statement, I would sure like to hear WHY? :)
