Recommendations for modest budget

Here's a great system almost identical to one I put together for my brother, and it sounds absolutely fantastic for movies and surprisingly good for music too.  Includes a sub that will get you down to an honest 20Hz so you'll really feel earth-shaking explosions, etc. in your room, and the critical center speaker really delivers the goods.  This system will make your soundbar sound like a bad joke by comparison.  All of it is new with warranty, and the total cost is within your budget at $1978.  All you need to add is cables/interconnects, and @grannyring here can build you some really good Dueland wires that'll work great and won't cost too much.  Hope this helps, and best of luck in your search.

Two questions for the OP:
1) Do you mind used equipment?
2) Do you need 4K Video?

AVRs become obsolete quickly and have very little resale value.  The market for non 4 K AVR is infinite and you can probably get a great piece for virtually nothing .If you insist on 4K you can supplement it with something like Apple TV as a source and as a music streamer to boot.  A decent BRP can be had for under $100.  That would leave the bulk of your budget for a Speaker/Sub combo, or again you might be able to score big in the used market here.  The upgrade as funds allow

1)I don't mind used equipment at all.  

2)4k is important and I stream that content through an Xbox One X
