Pay attention to the music.
If it feels right rather than sounds perfect you've got it.
Only listen to the components or your friends advice if you feel somethings not where you want it.
Move your speakers, placement is king.
If you're just starting try and get a single medium (cd, records, dig, tape, tuner etc.) sounding good to you before adding the rest in. It helps to focus the money on a decent end to end path first
Seek therapy, once in you're in for life
