Node 2i use with external DAC


I recently purchased a Node 2i that I use as a streamer and DAC that is plugged into a Schiit Freya + Preamp powered by two Vidar amps.   Wondering if it would be worth buying one of Schiit's higher end DAC's or is the DAC inside the Node 2i sufficient enough where there won't be a noticeable difference?

Gungy and Yggy are definite upgrades.
An Ayre Codex would be my choice on a budget

Gumby and Yggy would be a nice upgrade with the Node 2i. I used the Yggy for a while with the Node2i.

Also consider one of the Denafrips DACs. These are also an excellent value. I'm currently using the Terminator which is a definite step up from the Yggy, but isn't in the same price range. But from what I've heard, their lower priced DACs are quite exceptional for the $$$. 
Thank you everyone for the information. I like the idea of possibly upgrading to the TEAC rather than keeping the Node 2i and adding an external DAC such as the Yggy. Plus the fact that the Yggy is looking for balance in/out which the Node 2i doesn’t offer (Or am I misunderstanding) makes me wonder if the $2,500 addition would be in vein. Fun things to ponder. Thank you everyone.
I heard a real difference when I compared the Node 2i's own DAC with my MHDT Orchid R2R tube DAC (about $1200). Makes sense, right? Node 2i is just $500 and only a small fraction spent on their DAC. 
Don't limit yourself to schiit DACs. Look into some good tube based R2R dacs.
