If someone handed you this system, what would you change?

I was reading the latest post from a member here describing the rabbit hole he went down to find the perfect system. Lots of money spent upgrading lots of different gear. Made me wan to pose this question, and I ask it with this in mind. I am very happy with what I have, but if someone with extensive knowledge were to be handed this setup, what would this person do to swap out/add equipment that would really make a noticable difference. What, in your opinion would you want me to consider. (I will not take as an insult to anything you may say and I do have some pre-conceived ideas as to where this may go, but I really want your opinion)

My system from source to speakers:

Node 2i music streamer with Deezer as prefered music service
Mini DSP DAC with Dirac Live calibrated for my 17 X 25 room
Emotiva XSP1 Pre Amp (with home theater bypass function allowing a yamaha            receiver to take over on movie night). Then through balanced connection to:

Emotiva XPA gen 3 Power amp at 400 WPC bi-amped into mids and highs of speakers, and also from pre-amp directly to speakers that have 700 WPC to base drivers of speakers

Speaker wires from power amp to speakers are from Big Ear audio in Tempe Arizona. Owner builds his own cables; paid $800

Speakers: Legacy Audio Focus XD (again, bi amped from power amp and internal power built in to the speakers.

So, that's it. I went with as good as I could when I put this all together at about the same time 3 years ago. I am still really enjoying it BUT..... I feel a hole burning in my pocket for the next upgrade if needed. What do ya think
