Welcome!
Have the following suggestions:
1.) Develop a good listening room (insulated, not squarish or small, and dedicated);
2.) Pick loudspeakers that suit your tastes and room after careful auditioning (bring your favorite music, limit yourself to no more than 4 auditions per day, take notes to force you contrast each and reinforce aural memory);
3.) Find a power amp that serves the loudspeakers best or better yet buy active monitors where the manufacturer does that for you for each driver;
4.) Invest in a good streamer/DAC and discover the world of music, conveniently and inexpensively.
