You are fortunate and probably not obesessive. I have fiddled with a system that grew to two systems then to three for about 5 years now. I experimented to find those things in audio whose sound was most pleasing to my ears. There is so much variety in the way designers think a piece should sound that it is easy to get sidetracked from where you thought you were going.
I started with a reciever and ended up with separates. I started SS and ended up with tubes. I have finally cornered the type of gear that reproduces music as it pleases me. Each step though has revealed a new level of pleasure in the fidelity of reproduced music. The journey has been been almost as pleasurable as the destination.
It is great that your system pleases you because that is really its sole purpose.
