For that money I hear a lot of people are saying room treatments. Ok spend a grand on room treatments and the rest on the system. Don’t worry about cables. Very small improvements IME in the level you are looking at. Just an example of one of my systems:
Focal 836W rated 8 - $700 (drove 2 hours each way)
Jolida CRC 302 upgraded vintage rca input tubes rated 9 - 550
Burson Dac new model rated 9 - $600
This is my favorite most musical system in the house.
in a normal size room at reasonable volumes room treatments mean less unless you are sitting farther away. They matter for sure…
pick your transport or streamer or record player and done.
Deals come up if your quick and need to be patient. Guy like me checks daily on all the sites 😜. 6k buys a real nice system used if you buy right.
