Shadorne, I think you got it right, it is both:
- a form of compulsive disorder, yes, desire to try them all...
- a perception that it can always be improved
I must say that the better my system, the shorter the interval without a change..my first system lasted 5 years, then 2 then 1 then months down to weeks...before I got off (on?) the wagon, sold everything and started fresh in a new direction. It all depends if this is solely about the music or also the hobby. being both to me is great and I do not see why it should be a once-in-a-lifetime purchase: enough of my wife to deal with for ever.
