Building a synergistic system. What to buy?

Yes,  another  "help me build a better system" post.

Using new or used items currently available on the site or other forums, what would you choose to build a synergistic system for a 12 x 15 foot apartment room?

(Speakers have to work close to wall, btw.)

Music will be done by Bluesound Node streamer that I already have so no phono stage is needed (but maybe better dac if $5k budget allows). I'm guessing an integrated is the best way to go and matching speakers that will fill the room properly without a sub while still getting decent low end extension that doesn't go too deep? And annoy my apartment neighbors. For now, ignore interconnects and wires. Just list the current items available to build an apartment system with integrated and speakers for $5,,000 or less. Thanks!
