I'm only in my late fifties at the moment, but my life story really looks a lot like yours.
It's always good to know that we are not alone living with this wonderful "obsession".
By the way we are sharing loudspeakers taste as well, since I've been listening to my Avantgarde Trio with four 225 subs for long time, now.
I wish you all the best and thank you for sharing
