1. Learn to listen: compare different recordings of the same music, easiest done on classical music. Watch out for phrasing, room echo, dynamics etc.
2. Listen to learn: change speaker positioning gradually using the same piece of music. Change positioning of isolation feet under equipment (near the power supply, under output transformers, etc.)
Gradually change VTA and azimuth on your cartridge. Change tonearm cable (most important) as well as other interconnects as well as speaker cables. On digital try galvanic isolators for ethernet as well as USB.
3. Enjoy the music. Don‘t overdo the tuning
