THIS IS A GREAT POST!!
There is nothing I like better than "misery loves company" types of issues. Firecracker, mark my words; There will come a day when compromise will be the topic and the wife will question your sense of reality regarding your audio sickness. I had 14 years of bliss never having to discuss a purchase or look for approval when purchasing that $10,000 amp...then came the kids! Now it's a different world (as it should be) and the questions, dis-approving looks and the dreaded, "what in the he!! do you need THAT for?" is common place.
My suggestion is, ride the wave as long as possible while working your butt off to get a better job to justify the expense of new equipment and a new house with a room dedicated to your system.
Much of this is "tongue in cheek" but there WILL be questions eventually...be prepared ahead of time!
