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.

Listen to as many different speakers as you can. It is really about your taste in sound not what others tastes happen to be. Be careful though check the amp/preamp driving the speakers. Tube units will color the sound, some like this some don't, just be sure you are hearing the speaker and not the coloration. Spend a lot of time doing this - box speakers, actives, planars, and, if you can find them - horns. Once you are convinced that you like a given set of speakers and they are indeed an improvement over what you have, only then start looking for the electronics. Your speaker choice will drive your options for the amplifier. Worry about your source last and the only real choices there are digital vs analog and then if you choose digital - standalone cdp vs pc based with DAC. If you choose digital, particularly a standalone cdp there is no reason to spend much of your budget here. Do not spend any significant amount of money on cables. Blue Jean cable is a good choice for interconnects speaker cables etc. Mogami is also a good source for speaker cables. Any power cord will do. Realize that your room acoustics will also play a large part in the sound so be prepared to make adjustments there.
If you start with speakers, you are adding a huge unknown quantity at great expense. When you add new unknown electronics, you have absolutely no idea which component is contributing what, to your overall sound.
His present speakers are a very well known quantity. He can evaluate, each time he adds something new. How would a reviewer be able to make a valid statement about any component, if he threw in a basket of new components?
Without a lot more feed back from the originator of this thread; we are passing gas in a high wind. This is quite irrelevant.
The best electronics I have heard for the money and competitive with most anything I have heard is the combination of the Lightspeed Attenuator ($450) with the Music Reference RM10 MKII ($1,950). If the 35 watts is enough to drive a speaker you like, you will not do better at anywhere near the price point (those are new prices).
