After 7 years, I am still getting push back from my better half regarding new audio purchases. Has anyone successfully converted their spouse to appreciate the hobby? if so, please enlighten me!
Quit your full-time job, start your own audio business, and justify any speaker, turntable, room treatment, music, etc. purchases as "necessary business expenses" that are required for R&D (and there is a lot of truth to this!).
Just be prepared to work harder than you ever have before, but as long as it is a passion (labor of love), it is all good, and to the spouse, it is all justified if you are paying the bills, putting food on the table, etc.

Before those days, I was in your shoes getting lots of "push back" regarding audio purchases (half the gear I would start modding within days and she didn't get that part, either

).
The other suggestions above are probably better, but I just wanted to share my experience

Happy New Year!
