Hey no need to make explanations / justifications for "normal" behavior!
I have sold 4 audio items in my life - two reel to reel decks and a pair of Epos 11 speakers (wish I kept those). And I did give away a pair of my first homemade speakers made in high school. Everything else I still have.
I will do an inventory ... The only thing more sobering is keeping track of all the $$ expended on this hobby ...
The wife can't complain much as most I bought before we were married!
