Number of yrs. to reach the finished line?

My quest will never stop for as long as I can hear at least a single note. That doesn't mean that I am going to spend a fortune though; just $500 on every piece on average including a set of isolation cones, no more.

At some point you would have to change the listening room and possibly the house. How many of us would go that far?
Even now my modest $7.5k in used prices system would sound much better if I could move it to a better room which I cannot do. But that wouldn't stop me from upgrading. Though my stereo is not a true hi-fi yet it is very sensitive to even small changes; that's good to keep the hobby going. It is not at all only about music, it is also very much about the sound as we all know.

Addiction or not, if it is more or less under control it's OK.
