spend on the streamer or on the DAC ?

I a considering splashing north of 5000 (euro) for a new source for my rig (MOOON 340i, OPERA QUINTA speaker, McIntosh SACD, Node2). Better to spend more for the DAC or the streamer ? I was thinking about a Schitt yggrasil.Or would it make sense to spalsh on a more expensive DAC and use the Node2 as a streamer, or, for that matter, stream from my Macbook Pro. Regards.
I was pretty much in your exact same place last spring. I planned to spend $5-6k on a DAC to upgrade from my Node 2 (not 2i). I planned to use the Node as a streamer into the new DAC. Looked at a lot of different units (reviews, specs, etc but didn’t try in house) and finally decided on a Mytek Manhattan II. It just so happened that Mytek was running a special where they discounted the Manhattan by ~$300 and threw in a free network card.  I asked them if they would discount further if I didn’t get the network card and they offered me an additional $300 discount. The network card lists for either $1200 or $1500 can’t remember but it seemed like a better deal to go ahead and get the card. 
Initially tried the node streaming into the DAC and instantly the SQ was orders of magnitude better. The smile on my 18 year-old’s face said it all. After a few days I started using the network card to stream rather than the node and that resulted in another increase in SQ but nowhere near the same magnitude. I think JJSS49 above said 7-8 out of 10 on the DAC and 1-2 on the streamer and I’d say my experience was similar. 
I thoroughly enjoyed my Node 2 for a few years but I expect you’ll be amazed at what digital sounds like when you make the upgrade you’re considering. My experience with Mytek was great and I fully recommend them (I bought direct from them).  Let me know if you have questions about the Mytek Manhattan, etc.  
I expect you can’t really go wrong with any of the DACs at that price point.  Look forward to hearing where you land. 
Just gonna state for the record, that asynchronous USB from computer to DAC and then on to the rest of the system is superior in pretty much every case to whatever streamer you’re using and the gymnastics it’s doing to convert the bitstream to either SPDIF or Toslink. Async USB doesn’t exhibit the clocking issues that either of those connections are plagued with.

Just sayin.
My local high end dealer have put multiple systems together for shows and I noticed the budget allocation roughly was 40% streamer and 60% DAC. 

Personally I use the Innuos Mini running Roon/Tidal into RME ADI-2 DAC and I am very pleased.

I have been considering moving to an FPGA-based DAC to be "future-proof" and the PS Audio with a built in bridge (streamer) comes to mind. 

Lately, though, I have been dreaming of the adding the Innuos Phoenix re-clocker to my setup as it is getting excellent reviews. And the RME just released a new version of the DAC. Life of an audiophile :-) 

Eventually check out Darko audio on the web and youtube. Some very good and educational stuff. 
I would emphasise here that the performance of the combined streamer/DAC is affected considerably by the configuration of your wired Ethernet delivery. I would go for a 50/50 streamer DAC ratio, connected by USB if possible, with a really good cable, then use the ENO Ethernet filter (Network Acoustics) to remove the ‘noise’ picked up in the Ethernet cabling. This really makes your investment in streamer/DAC come to life. All streamers gain from this, except the Naim 555, as it has measures built-in to eliminate this, hence why it sounds so good.
I have stream from Chromcast audio digital out bluesound node 2i digital out cocktail Audio X45 digital out Allo digi signature USB out and more streamers to my Preamp DAC Michi P5 zero difference
analog out is different story
like others said the interface of streamer APP is more important to me that’s why I’m using Naim Atom Uniti as a streamer only to my preamp the interface of Naim app is amazing compare to Cambridge 851 app auralic G1 app Bluesound app
