@op Try to hear a pair of Wilson Sabrina X's with some quality amplification and source (CD/Streaming/analogue of your choice) as a starting point.
If organic is your criterion but you need power for the kind of music you listen to, probably a transistor power amp that is at least partly biased into class A.
Budget for room treatment if the room is not already sorted.
Only suggestions as possible starting points because the possibilities are endless.
