Can I use a streamer with an internal dac when I have an integrated with an internal one?

My Mytek Brooklyn BB has essentially taken me out of the market when it comes to streamers and DAC's.  It mates near perfectly with my modest, admittedly slightly mellow PrimaLuna/NOLA Boxer system. When the source material makes it available, I get excellent soundstaging and lovely timbres. Mytek was also both gentle & responsive when I mistakenly thought the component needed warranty work. My problem turned out to be simply a matter of changing a couple of settings on my Windows laptop, something that Mytek did when I let them remotely access my computer.

I'm looking at Aurender N10 and Auralic Aries G2.1
both without Dacs

I would guess the Dac in the mytek would be better than the one in the integrated. You could absolutely run it either way. 
I have not seen too many reasonably priced streamer only options without dac. Would be interested to hear about any as I don’t use the dac inside the bluesound node.

To clarify my idea of reasonable for a streamer would be 1k or under. 

My streamer is my MacBook Pro with roon. My external dac is Schiit bifrost with usb unison. This dac is modular for unplugging and plugging in new boards as the technology changes. No need to buy new or send back for upgrades or software updates. Also like how MacBook is updates constantly. Biggest sound improvement I had with this combo was moving from WiFi to cat6 for connection. This change was a 100% sound stage and bass improvement for quobuz.
