What you have is a big waste of money. You don't need a $2k receiver for a space that size. You could get something $400 and with that amount of space, they'd probably sound the same. For the speakers, they've available very cheap used on Craigslist. Speakers aren't like a car. They don't quickly break down over time.
For a space that small, everything you have is overkill. You're spending $8000 to address an emotional need for a stereo. You're not fulfilling a need for a certain type of sound.
You could spend $2k on that space and then spend the rest on something more important than things. Take a family vacation, trip for yourself to Europe, update your house, take friends to dinner, give to charity, take out your significant other, etc. Should you wish to indulge yourself, there are a lot better things you can do with $6k that don't involve sitting at home playing video games.
