Many times changing components or cables, it could just be a change of sound not even improvement, on my experience it took two good mentors, and many many hrs of listening, before I was able to learn what is change or improvement, sound or music...iam so impatient to wait for the cable or component to settle, then I just jump into conclusion right away wow it's a good cable? When I rush most of the time Iam wrong.Then I realize reviewers take months before they write their reviews...I realize it's good to wait in this hobby....
