Upgrade Suggestions - Entry Level Setup

Room panels.

The Dali's have a tilted up tweeter level, which makes them great for some, but they benefit more from a good room.

Instead of attempting DIY, talk to GIK acoustics.  They make very reasonably priced, very effective materials.

I'd leave the cables for last.

First off, thanks everyone for taking the time to respond.  I really appreciate it. 

 Djones51, I have thought about getting an external DAC but everyone's says I need to spend more than $1,500 to beat the Node 2i.  Any particular recommendations that will share a good synergy with the rest of my setup?

cd318, As for the amplifier, I was considering the Rega Brio and Marantz PM 6006.  I got this system just 6 months ago.  My wife will kill me if I went for another expensive equipment anytime soon.  So I am about 6 months away from upgrading the amp and dac.  But I'd love to get recommendations on Amps and Dacs I should keep in my consideration set. 

In the meanwhile, any other ideas?  Are my cables decent or should I consider upgrading?  Desktop stands like these?  Right now I have them on my TV cabinet with the stock bumpers that were supplied with the speakers.

To be honest, I don't even know what I want changed. Just feels like something's missing or could be better. lol

Topping D50 for $250, Sabaj D5 for $470, Schiit Modi 3 for $99 any of those would better the Node2i DAC.

Dahli makes a very fine speaker, and one of your absolute best moves would be to upgrade within the Dahli brand. 

That is as straight and efficacious advice as you will see here.  :) 

as a long time Dali owner I was going to say same as Douglas...
