i will not say that obsession is never a good thing...
So much discoveries in humankind comes from obsessed people from Archimedes to Tesla and beyond...
But obsessing about "sound" in this way is interesting case but i am not sure it is as you said a good thing, because perfectionism obsession is not the optimal attitude in this acoustic/ musical case ...
it is certainly not a road to take nor a person to imitate....
but as everybody i marvel at his room/system and i would love listening it... His family who paiy the real price are not so much interested by my curiosity...
Obsession is never a good thing.
