I commented here quite some time ago. I hope your system fully survived your children's younger years. I've been very lucky with mine.
I bought a turntable recently and my 10 year-old daughter and I have been making the rounds at flea markets and thrift shops hunting for vinyl. It always startles the sellers to see a kid near a record.
It's an interesting (eg: terrifying) challenge to have a really satisfying hifi system and children. Just look at all the sellers on A'gon who are quick to label their gear as being from a childless environment.
I have a tube amp and exposed speakers in my tiny Manhattan apartment. It's all naked and at risk during wild playdates for my six year-old, but so far the hifi gods have smiled on us.
It's very easy to lose sight of the purpose of this gear and become a fetishist, but when my kid dances to Sharon Jones or gets lost in a string ensemble, I understand what I spent my money on.
So, at some point a light saber will smash a vacuum tube or a curious little finger will crush a tweeter and I'll have to remember that it's about the music.
You have some beautiful audio gear - I hope you'll keep perspective when it happens.
