Upgrade Suggestions - Entry Level Setup

Hi,
you may also consider KEF LS50 they will give you more authority and better bass. From there a better amp would be my second upgrade when ready.

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.

Best,
E

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.  :)
