Suggestions regarding audio?

[Werdsniper2]

So I just moved into a new apartment a few months ago, and after getting all my furniture set up and buying a brand new 4K TV, it's time to look into audio.

Anyone have any suggestions/tips for a decent "mid-range" surround sound set-up? I can't fully enjoy my Blu-rays without a proper set up.

I don't want something cheap that I'm not going to enjoy. I'm willing to pay more for something that is going to give me solid results. I just can't go all out and throw down a ton of money for top shelf products.

I know virtually nothing about audio systems (not familiar with what equipment is needed), so any help would be appreciated. As for my living situation - my living room has very high ceilings which does produce a bit of an echo, if that helps at all.
