Upgrade Suggestions - Entry Level Setup

Hi everyone,

Here's my current setup.  I have this itch to upgrade something but wasn't sure what.  My room is pretty small (10X12 feet), so I really like the small form factor of the speakers.  Not to mention, I love the Dali sound. 

Given that, what are some quick wins / pocket-friendly upgrades to improve SQ? And what will be some medium to long term upgrades?  Basically, where would you go from here?  Based on your suggestion, I am going to try to audition and see what I like.  Thanks folks!
